Product Spotlight: AudioControl A600.4

AudioControl A600.4

If you have been around the car audio industry for as long as we have, then you have likely used an audio processor in your vehicle. This veteran company is recognized worldwide for its line output converters, equalizers and crossovers. A few decades later, the brand has introduced several series of amplifiers. Their latest offering is the Altitude Series. In this spotlight, we’ll check out the four-channel A600.4 amp.

AudioControl A600.4 Specifications and Features

The A600.4 four-channel amp is rated to produce 100 watts of power per channel when driving four-ohm loads. That output increases to 150 watts per channel when driving two-ohm loads. When each pair of channels is bridged to a four-ohm load, the amp produces 300 watts of power.

With respect to performance, the amp has a THD+N specification of <0.21% and a signal-to-noise ratio of 107 dBA referenced to full power.

Let’s start with a unique feature included in the A600.4 – Valet mode. When a 12-volt signal is applied to the Valet input, the maximum power the amp can produce is reduced to 25% of its maximum output. The malfunction indicator LED will illuminate orange when the amp is in Valet mode. If you are concerned about someone abusing your car audio system, this feature is perfect for keeping your speakers safe.

The A600.4 is also equipped with AudioControl’s Great Turn-On (GTO) circuit. The amp can be activated by applying 12 volts to the remote input. Alternatively, when in GTO mode, the amp will detect the ~6-volt bias on the speaker wires of a factory-installed or aftermarket radio. If your installer is integrating the amp into a vehicle with a full-bridge amplifier, Audio mode will monitor the inputs for the presence of an audio signal to wake the amp up.

Another unique feature of the A600.4 is its use of Linkwitz-Riley alignments on the crossovers. While the slopes are still shallow at 12 dB / Octave, they will sum smoothly around the crossover point because the signal will be -6 dB at the knee frequency. Butterworth crossovers are only at -3 dB at the crossover point, which results in a 3 dB bump when the acoustic signals sum. In short, your system will sound better and have improved clarity around the crossover frequency with this design.

The amplifier is based on an aluminum extrusion and features uniquely styled end-caps for a clean appearance. A removable panel on top of the amp conceals all the signal adjustments and the set screws for the power and speaker connections.

All connections are made along the front edge of the amp using high-quality terminal blocks for 4-AWG power and ground, and 12-AWG speaker wire connections.

Signal Processing Information

Each pair of channels has a sensitivity control that is adjustable from 0.5 to 6 volts on the RCA inputs and 1.5 to 20 volts on the speaker-level inputs. The speaker inputs are on an eight-pin Molex plug, and AudioControl calls this the LC Direct connection. The amp has a two or four-channel input switch. In two-channel mode, the signal on channel 1 (LC Direct or RCA) is copied to channel 3, and the signal on channel 2 is copied to channel 4. This is ideal if you are connecting that amp to something like a Bluetooth streaming device as a signal source. Each pair of channels has a Max input indicator. This LED will illuminate when the input is maximized and should flash occasionally when playing music recorded at high volume levels.

AudioControl A600.4
The A600.4 has clean lines and a modern aesthetic. It’s also small enough to fit under the seat of most vehicles.

The crossover on each pair of channels is adjustable between 50 and 500 Hz, or when the x10 switch is enabled, 500 to 5 kHz. This is enough range to handle subwoofer to midrange speakers, or midrange to tweeters. The crossovers on both channel pairs can operate in high- or low-pass mode to ensure maximum system design flexibility.

The amp has an RCA output terminal that can be used to feed an audio signal to an additional amplifier like the A800.1 800-watt monoblock to power a subwoofer.

Finally, there is a connection for an optional ACR-1 remote level control. When connected, you can adjust the output level of channels 3 and 4 to suit your mood or the music you’ve chosen.

Product Spotlight: Hertz CP4.800

Hertz CP4.800

When choosing an amplifier for your car audio system, consider quality, features, physical size and power production to ensure a worthwhile investment. The mobile audio amplification experts at Hertz have recently released a new product line called Cento Power that specifically addresses these factors. In this spotlight, we’ll look at the four-channel CP4.800 amplifier.

Hertz CP4.800 Specifications

The Hertz CP4.800 is, as mentioned, a four-channel amplifier. The amp is rated to produce 110 watts of power when driving four 4-ohm speakers. That output increases to 190 watts per channel when driving four 2-ohm speakers. Hertz is generous with their configuration specifications. If one pair of channels is driving a set of four-ohm speakers and the other is bridged to a subwoofer, the mono channel can produce as much as 400 watts of power. If both pairs of channels are bridged to four-ohm speakers, the output is 380 watts each. All specifications are provided at 1% THD.

In terms of performance specifications, Hertz rates the amp as having a signal-to-noise ratio of 101 dBA when driven with 1 volt of input. Concerning harmonic distortion, the amp is rated at 0.02% when producing 100 hertz at 70% of rated power. While both numbers are quite good, keep in mind that the specifications aren’t compliant with ANSI/CTA-2006-D industry standards.

A key highlight of the Cento Power CP4.800 is that it qualifies as a true High-Resolution product with frequency response rated as 10 Hz to 48 kHz. If you are playing FLAC or WAV files through a high-resolution source unit, the extra bandwidth is a blessing.

The CP4.800 is impressively compact for its power output capabilities.

Amplifier Layout and Connections

The CP4.800 is based around a compact cast aluminum heatsink that’s 8.07 inches long, 6.1 inches wide and stands 1.89 inches tall. All the connections are made along the front edge of the amp, and the controls are concealed beneath a removable panel on the top of the chassis.

The amp has a two-position terminal block on the left end that will accept 4-AWG power and ground cables. Beside that is a 40-amp ATC fuse to protect the amp against reverse polarity power connections. From there, we have six Molex connectors. The first plug on the bottom has four RCA jacks on pigtails for the main low-level inputs. Two additional RCA output jacks can be used to feed another amp. The next two plugs have four positions and are the speaker-level inputs to the amp. The RCA inputs can accept an input range of 320 millivolts to 8 volts. The speaker-level inputs will take 1.6 to 40 volts RMS.

Above the RCA inputs is a two-position jack for the remote turn-on input and output. Besides that, there is another two-position jack for the remote volume control. The optional HRC-02 control allows you to adjust the output of the rear channels to fine-tune the system when the low-pass filter is active.

The last plug is a larger-gauge eight-position jack for the speaker output wires.

Power and ground connections are handled by a large terminal block.

Signal Processing and Adjustments

As mentioned, all the adjustments and controls are located on the top of the amp under a removable cover. Starting on the top left, there is a switch for the Automatic Remote Turn-on (ART) feature. When enabled, the amp should turn on when the factory source unit connected to the speaker-level inputs is activated. Below that is a button to select the source for the rear channels. They can be fed from the front inputs in a two-channel system or the rear inputs for complete system control from the source unit.

Each pair of channels has a level/gain control, a crossover function switch and a crossover frequency adjustment control. The crossover function switch selects between high-, low-pass, or full-range operation. The crossovers have second-order 12 dB/octave filtering that’s adjustable between 50 Hz and 4 kHz.

The rear channels include a bass boost control that can add up to 9 dB around 50 Hz. Finally, each pair of channels has a mono input selector. With both enabled, the amp could be used as a two-channel unit where the Left RCA feeds both front channels and the Left RCA on the rear input feeds both rear channels. The mono button is also helpful if your radio has only a single subwoofer output jack.

A Quick Look at Apple and Android Smartphones

Apple and Android SmartphonesLooking back to the Palm Pilot and the original Blackberry, we have been on a constant path toward having full-blown computers with us at all times. Fast-forward a few decades and it’s rare that folks don’t have a smartphone in their pocket or purse. Apple and Android smartphones have changed the way we communicate and are entertained.

In the mobile electronics industry, we have been working hard to find ways to integrate your smartphone into your vehicle to help you safely communicate and listen to your music. Dive into any discussion about smartphones on Facebook, and you’ll quickly see it turn into a battle of which kind is better. As each device changes, seemingly by the hour, answering that question is nearly impossible. With that said, there are definitely benefits and drawbacks to each. Let’s look at some cold, hard facts about the Android and iOS operating systems and their associated hardware.

A Brief History of the iPhone

Launched in the summer of 2007 by Steve Jobs, the iPhone was touted as a game-changer in communication technology. Apple retains a unique advantage over Android-based smartphones in that it controls not only the hardware chosen for the device but the software as well. The iOS operating system is designed and tested to work together with the iPhone.

iPhone Complaints

Apple and Android SmartphonesWhat company doesn’t have haters? People either love the iPhone for iOS for its interface, associated software and approved hardware accessory devices or hate it for its monopolistic approach. Few people like having to use iTunes to load their music and the cost of MFI (Made for iPhone/iPod) approved cables and devices definitely raises their cost.

Is there a benefit? Definitely. When you buy an approved accessory, you know it will work. When you transfer music, you know it will play. You may lose some of the independence of doing what you want when you want, how you want, but the infrastructure exists to make owning and using an iPhone as trouble-free as possible.

Apple is often criticized by Android users for being late to the party with new features: “Oh, you added facial recognition to the iPhone X and wireless charging to the iPhone 8! That’s great, Android phones had that last year.” Maybe it takes longer for Apple to test these technologies. Maybe the development and testing time for each new phone takes a lot longer. We may never know, but it sure is nice when the features arrive and work flawlessly.

iPhone in the Car

Apple and Android SmartphonesApple led the automotive smartphone connectivity battle with CarPlay. CarPlay was launched at the Geneva Motor Show in 2014 with Ferrari, Mercedes-Benz and Volvo as its first automotive partners. CarPlay offers an interface that mimics the icon layout on the phone to make using the system intuitive.

CarPlay allows users to use the Siri voice recognition engine to perform tasks like listening to text messages, making phone calls, selecting music and choosing navigation destinations. You don’t have to look at the screen at all to initiate any of those tasks.

With Apple under control of the CarPlay software, both OEM and aftermarket infotainment system manufacturers need to send samples to Apple for testing and approval before they can be sold. Apple works at its own pace, and we know this can cause delays. Are they worth it? If the system works the way it should, then most definitely.

Android-Based Smartphones

Apple and Android SmartphonesDeveloped by Google, the Android mobile operating system started development in 2005 and was launched in 2007. At the same time, the Open Handset Alliance – a consortium of hardware, software and telecommunication companies – was launched to advance open standards for mobile devices. The goal of the Open Handset Alliance was to create an open competitor to Symbian, Blackberry OS and iOS-powered devices. The first Android-based device was the T-Mobile G1, developed by HTC and launched in September 2008.

A fun fact about Android is its naming convention for each major release. While this practice is not uncommon, the names are rarely shared with the public. In order, the code names have been Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow, Nougat and, most recently, Oreo. Clearly, the Android development team has a snacking issue.

Is Free Good?

Apple and Android SmartphonesAs we stated, the Android mobile operating system is released by Google under an open source license. This means that phone manufacturers don’t need to buy or license the operating system. This can reduce development costs and accelerate the focus on new technology.

As with most things, for every silver lining, there is a dark storm cloud nearby. With phone manufacturers like Samsung, Huawei, LG, Sony and HTC each creating their own hardware and implementation of the Android operating system, updates for each device are at the mercy of the manufacturer and the wireless carriers. With Android about to roll out Version 8.1.0, not every device will get an upgrade.

In May 2017, coinciding with the launch of Android 8.0, Google announced Project Treble with a goal to streamline and simplify the update process for Android-powered devices. Only time will tell how successful they are.

Is Easy Good?

If you want to put a few songs on your Android phone, connect the USB cable to your computer, and drag the files to the Music folder. You can manage the files on your computer however you want, or not at all – if that’s your cup of tea. Similar folders exist for Pictures, Podcasts, Ringtones and Movies. You can treat them the same way you would a USB memory stick.

When Apple announced the iPod would move from Firewire to USB, radio manufacturers were quick to adopt interfaces that would allow control playback of the songs on the device in the car. This adoption took a lot longer for Android, and even up until last year, some source units could not play music stored on an Android phone by simply connecting the USB cable.

Bluetooth Problems

Apple and Android SmartphonesWith Apple and Android smartphones, Bluetooth connectivity is a big issue. Almost everyone has a Bluetooth hands-free solution in their car, so being able to use your phone with it is crucial to your productivity. Apple hasn’t been flawless in terms of backward compatibility to older source units, but for the most part, they seem to work well. Android, on the other hand, has been plagued with connectivity issues that vary by the phone manufacturer. Several aftermarket radio manufacturers cringe when dealers or consumers call about Bluetooth issues from specific brands.

Imagine if you update your smartphone and you can no longer connect to your vehicle’s hands-free system. With Apple, you can complain at the Apple Store or log into their support website. Though they won’t admit it outright, they pay attention to these issues and in many cases, fixes are released in updates.

If you own an Android-based phone, whom do you call when something doesn’t work? The store you bought the phone from? Your carrier? The manufacturer? Google? Simultaneously, each of them and none of them are singly responsible for the issue, nor can any one of them directly help you find a solution. Sure, there are exceptions, but with the open source philosophy of Android, connectivity with third-party devices is a lot more variable.

Android in the Car

Apple and Android Smartphones Android Auto was announced in 2014 as a joint effort between 28 automobile manufacturers. The actual Android Auto app was released on March 19, 2015; in May 2015, the Hyundai Sonata became the first vehicle to offer Android Auto support. Android Auto offers similar functionality to CarPlay, but eschews the menu-driven foundation and provides information about the function you are using on the screen. Voice commands and features work similarly to CarPlay.

Android Auto has an advantage over CarPlay with Google Maps and Waze. Both of these navigation solutions are considered superior to Apple Maps. You will find that many Apple users, unless they are using CarPlay, use the iOS versions of Waze and Google maps for their navigation needs.

Which Phone is Better?

Apple and Android SmartphonesOur goal isn’t to determine a winner in the battle of Apple and Android smartphones – that’s up to each individual user. If you use Macintosh-based computers at home, you may see no better option than to choose an iPhone. If you like the freedom of Android open architecture, there’s absolutely nothing wrong with that.

Integration for Apple and Android Smartphones

No matter which phone technology you use, your local mobile enhancement retailer can help you integrate your phone into your vehicle. CarPlay, Android Auto, wireless charging, audio streaming, hands-free calling solutions or even a custom mounting bracket are available for most vehicles. Drop by and see how they can make using your smartphone in your car safer and easier.

Everything You Need To Know About SiriusXM Satellite Radio

SiriusXM Satellite RadioIt seems you can’t go anywhere these days without hearing or seeing evidence of SiriusXM Satellite Radio. Satellite radio is touted as a commercial-free entertainment solution that can be accessed almost anywhere in North America. With more than 175 channels of music, comedy, sports and talk radio available 24 hours a day, there is always something to listen to. Let’s look at the how satellite radio began, how it works and why it has been so popular.

The Early Days of Satellite Radio

XM Satellite Radio evolved from the American Mobile Satellite Corp. AMSC was a consortium of companies that wanted to use satellite technology to broadcast telephone, data and fax information around the country. In 1992, AMSC formed the American Mobile Radio Corp. to develop a satellite-based digital radio service. AMRC was spun off from AMSC in 1998 as XM Satellite Radio. XM Radio was first to broadcast, launching on Sept. 25, 2001.

In 1990, Sirius Satellite Radio set out to attract customers and vehicle manufacturing partners to its proposed music service. After years of planning, development and licensing, Sirius launched three satellites in July 2000 and started broadcasting in January 2002.

Satellite radio was the hot ticket in the early the early 2000s, and partnerships with automakers were crucially important to each company. Sirius gained the support of Ford, BMW and Chrysler, while XM had General Motors, Honda and Toyota on board.

Satellite Radio Company Merger

SiriusXM Satellite RadioIn January 2005, the New York Post announced that Sirius and XM would merge into a single company on Feb. 19, 2007. The combined companies had about 14 million subscribers, but neither company had posted a profit. The result of the merger was SiriusXM – the brand we have now.

SiriusXM is now integrated into 75 percent of the new car market, with roughly 40 percent of those vehicle owners becoming subscribers. As of late 2017, there are about 32 million subscribers.

How Satellite Radio Works

Satellite radio is actually a very simple broadcasting system. The company has its main studios in Rockefeller Center in New York City and in Washington, D.C. Secondary facilities are in Los Angeles, Nashville and Memphis. The company plays music from its extensive catalog and has live performance spaces to host musicians and performers from all genres.

The information is broadcast to a set of satellites above the Earth that rebroadcast that information back to Earth. The broadcast covers most of North America. The satellite radio receiver in your vehicle (car, truck, boat or aircraft) uses a compact antenna to pick up the signal and extract the channel of audio you want to enjoy.

They Really Have Satellites?

SiriusXM Satellite RadioWhether it’s a live performance, your favorite music or a great discussion about religion or politics, all of the information is combined into a complex digital signal that is transmitted to a set of five active satellites that cover North America. XM-2 and XM-5 are in a geostationary position above the Earth. That is to say, they stay in the same relative position all the time. Positioned about 22,370 miles above the Earth, the satellites relay broadcast information from the studio transmitters to all of North America, excluding the left half of Alaska. XM-2 covers the west side of the country while XM-3 covers the east.

The Sirius satellites also operate in geostationary orbits. Sirius FM-6 covers the West Coast while Sirius FM-5 is located south of New Orleans to cover the East. Early Sirius satellites (Sirius 1, Sirius 2 and Sirius 3) crossed the planet in a figure 8 pattern that had two of the three over North America at any time.

As you can see, there have been many satellites over the almost 20 years of satellite radio. In total, nine have been launched, with the most recent being Sirius FM-6 on Oct. 25, 2013. Sirius FM-6 was the first to broadcast both Sirius and XM transmission frequencies.

The Benefit of Satellite Radio

SiriusXM Satellite RadioSo, what’s the big deal? Why do people gravitate toward satellite radio? The answer comes from its coverage. You can make a road trip from Miami, up to Montreal, across to Vancouver then down to San Diego without having to change the station. If you want to listen to Howard Stern for the entire 90 hours of driving, you most certainly can.

Conventional terrestrial broadcasts (AM and FM radio) are limited in their coverage areas. In fact, the FCC regulates the strength of the signal (to 70 dBu, or decibels relative to one microvolt per meter of signal strength). That way, a station frequency can be re-used again in a relatively nearby location. The actual distance varies because of atmospheric conditions but usually covers 75 to 100 miles from the transmitter. Because each station is responsible for its own content, if spaced perfectly, you’d need to change stations between 60 and 80 times. In reality, you’d need likely a few thousand attempts to find a station that was playing the type of music you wanted.

More Than Just Cars and Trucks

SiriusXM Satellite RadioSiriusXM satellite radio services have been synonymous with marine entertainment systems since they launched. Many people have cottages or camps in very remote areas that have few if any radio stations at all, so being able to enjoy their favorite genre of entertainment is fantastic. Likewise, receivers such as the SiriusXM Sound Station let you enjoy music in your home.

Things You Didn’t Know SiriusXM Could Do

Most of us are used to having satellite radio entertainment in the car, but there are several other applications for the system as well. Many aircraft, both small and large, can get weather and location information using a SiriusXM Aviation receiver. In fact, many Garmin aviation-specific products have the SXM receiver built in.

SiriusXM Satellite RadioSiriusXM Marine provides weather information including lighting strike locations and radar, fishing information and more. Many Garmin, Raymarine, Simrad, Lowrance, B&G and Furuno devices are compatible with SiriusXM Marine.

SiriusXM Music for Business offers entertainment solutions that are tailored to different business types. Serve Happy covers restaurants and bars, and Shop Happy is designed for retail stores. There are channels for waiting rooms, spa and fitness businesses, banks and even music dedicated to use when clients must be put on hold on the phone.

Currently only available on OEM source units, SiriusXM Traffic and Travel Link provide traffic flow information as well as local weather, fuel prices, sports scores and even movie listings. Traffic information mimics that of terrestrial RDS-TMC services in major urban areas.

The Cost of SiriusXM Satellite Radio

SiriusXM Satellite RadioWith the need to replace satellites roughly every 15 years, license music, pay hosts and celebrities, SiriusXM requires a subscription to access its services. In the U.S., prices start at $10.99 a month for 80 basic channels. If you want some of the artist-specific channels and MLB, NBA and NHL coverage, that rises to $15.99. To add Howard Stern, NFL and NASCAR coverage, the price is $19.99. Adding the ability to stream Sirius XM to your computer increases any of the above by $4 a month.

Enjoy the Entertainment You Want, Almost Anywhere

Whether you are in downtown New York or venturing to Supai, Arizona (the most remote community in the contiguous U.S.), enjoying your music is easy with SiriusXM satellite radio. If your vehicle doesn’t already have a satellite radio receiver, drop by your local mobile enhancement retailer and ask about your options to add SiriusXM.

Product Spotlight: Alpine i407-WRA-JL

Alpine i407-WRA-JL

If you’ve been paying attention over the last few years, you’ll know that the folks at Alpine have been offering many different audio system upgrade solutions for Jeep Wrangler and Gladiator vehicles. These offerings range from head unit replacement solutions to complete audio systems with amplifiers and subwoofers. In this Product Spotlight, we will look at the i407-WRA-JL radio upgrade kit. Let’s check it out!

What is the Alpine i407-WRA-JL Kit?

The i407-WRA-JL is a radio upgrade kit for 2018 and newer JL chassis Jeep Wranglers and 2020 and newer JT chassis Jeep Gladiators. The kit includes an Alpine iLX-407 source unit along with mounting brackets, a radio trim kit, a new auxiliary input jack, all the wiring harnesses, a camera interface module, and an iDatalink Maestro RR integration module. The concept was to provide retailers with a package with everything needed to upgrade the entertainment system and prevent surprises in the installation bay.

The Alpine I407-407-WRA kit includes everything your installer needs to upgrade your Jeep Wrangler or Gladiator.

Jeep Radio Upgrade Kit Features

The included dash kit and brackets take care of ensuring the radio is mounted in place of the stock source unit and looks great. The dash kit is molded to fit the complex shape of the dash for a clean, factory-like appearance.

Alpine i407-WRA-JL
The mounting brackets and radio trim are designed to make the iLX-407 radio look right at home in your Jeep.

In terms of integration, the factory-installed backup camera on these Wranglers and Gladiators uses a communication protocol called Low-Voltage Differential Signaling (LVDS). This signal isn’t directly compatible with aftermarket radios. As such, the i407-WRA-JL kit includes an interface module that converts the LVDS signal into a composite signal so the camera will work with the included iLX-407.

The kit also includes an iDatalink Maestro RR interface. This data interface and harness allows the new radio to plug into the wiring connectors from the original radio and provides access to the Jeep’s data network. Information like vehicle speed, engine RPM and much more can be displayed on the radio. The climate control settings are also adjustable from the face of the new radio.

One item worth noting is that if your Jeep is equipped with the factory amplifier, an optional interface module called the KCX-F200INT is available to let the new radio connect properly.

Alpine iLX-407 Features

The double-DIN iLX-407 is the radio at the heart of the i407-WRA-JL kit. This radio features a 7-inch anti-glare touch screen with a resolution of 800×480 pixels. The hard controls are along the bottom edge of the front panel. Apple CarPlay and Android Auto are included, as is Bluetooth for hands-free streaming or phone calls. The tuner in the unit offers support for HD Radio, which dramatically improves the quality of FM radio. There’s an HDMI input on the rear of the chassis, so you can theoretically connect a gaming system or a laptop, if you want. There are two camera inputs and support for the SiriusXM SXV300 tuner module.

The I407-WRA-JL kit includes an interface that allows the LVDS factory-installed camera to work with the new radio.

If you want the best sound quality from your music, playing digital audio files from a USB drive is the way to go. The iLX-407 supports MP3, WMA, AAC, FLAC, and WAV audio formats with a maximum sampling rate of 48 kHz. The unit will also play AVI, MP4, MPG, MOV and WMV video files with H.264 or MPEG-4 video encoding. The maximum video file size is 4 gigabytes.

Audio Processing Features

The deck includes a four-channel amplifier rated at 16 watts per channel and in compliance with the ANSI/CTA-2006 standards for car audio amplifier power specifications. The triple preamp outputs are rated for up to four volts.

The iLX-407 is impressive in its audio processing features. It has a simple five-band graphic equalizer to let you fine-tune the system to your listening preferences. The more advanced crossovers offer adjustable slopes from six to 24 dB/Octave and filter frequencies from 20 to 200 Hz with high-pass filtering on the front and rear channels and a low-pass filter for the subwoofer output. There’s also a level control for each output, which many source units overlook. Oh, and the subwoofer level control can be adjusted from 0 to 15 with a polarity inversion option to potentially help the subwoofer’s output blend with the woofers in the dash and overhead sound bar.

The Time Correction setting screen allows your installer to dial in delays to each of the six outputs (which include the four built-in amplifier outputs) in 1 millisecond steps or set distances to the speakers in 3.4 centimeter steps. There are three presets available to store different Time Correction configurations. This is ideal if you want one alone in the vehicle or have a passenger, which requires different settings.

Alpine i407-WRA-JL
The equalizer in the iLX-409 includes presets along with user configurable options to let you fine-tune your audio system to your listening preference.

Jeep Radio Upgrade Kits

Alpine offers four Jeep-specific radio upgrade kits, including the i407-WRA-JL and a similar solution for older Wranglers called the i407-WRA-JK, covering 2007 through 2018 applications. If you want something fancier, the I509-WRA-JL and I509-WRA-JK kits include a 9-inch weather-resistant display, more advanced audio processing, and wireless smartphone connectivity.

If your Jeep is lacking in the audio department, visit a local authorized Alpine retailer and ask about the available Jeep-specific solutions. You can find an authorized retailer using the Store Locator tool on the Alpine website. For more information about the audio upgrade solutions available from Alpine, follow them on Facebook, Instagram and YouTube.
