Product Spotlight: Sony XAV-AX7000

Sony XAV-AX7000

Sony car audio continues to introduce new multimedia receivers with features that everyone, from the car audio enthusiast to the daily commuter, loves. The latest addition is the double-DIN XAV-AX7000 that features a new 6.95-inch bright touchscreen, Apple CarPlay and Android Auto smartphone integration and Sony’s High Power 45 watts-per-channel RMS amplifier for amazing sound! Read on to learn more about this impressive source unit.

High Power Amplifier for Better Sound

Sony XAV-AX7000Most radios and receivers on the market include a four-channel amplifier IC that can produce about 20 watts of power per channel into a four-ohm load. Sony’s High Power equipped receivers include a real power supply as would be used in a stand-alone amplifier. The power supply allows the radio to produce more than 45 watts of power per channel to a four-ohm load, and quite a bit more into a two-ohm load. That doubling of power helps keep your music clear and distortion-free when you crank up the volume.

The radio is compatible with both two- and four-ohm loads. Sony includes a configuration called Subwoofer Direct Mode, which allows your installer to use the front speaker outputs to drive one or more sets of speakers on the front speaker outputs, and use one of the rear speaker outputs to power a subwoofer system with a net impedance of two ohms. This flexibility allows for quite a few system configuration options and lets those people looking to stay on a budget with their audio upgrade aspirations get a complete system with a subwoofer without adding the extra costs of a small four-channel or subwoofer amplifier or the associated wiring and installation.

Bright Anti-Glare 6.95-Inch Display

Sony XAV-AX7000The touchscreen display on the XAV-AX7000 is the same size as that of the XAV-AX5000, but is brighter and features a new anti-glare coating. These properties make it much easier to see in bright sunlight situations common among convertibles, powersports vehicles and even motorcycles. The new coating is also compatible with polarized sunglasses, so you can still see the screen while protecting your eyes.

In keeping with the sports theme, Sony has made the frame around the AX7000 touchscreen and the five-button control panel beneath the screen are weather-resistant. No, you can’t take it snorkeling in Mexico, but it can handle a little rain, being splashed or being on a motorcycle or in a Jeep overnight without condensation forming behind the screen.

Apple CarPlay and Android Auto Smartphone Integration

Sony XAV-AX7000In terms of smartphone connectivity and features, the AX7000 is the same as the AX5000 in that it includes both Apple CarPlay and Android Auto voice control solutions. Once your phone is connected, you can request commonly used functions like sending text messages, making phone calls or choosing music by talking to the radio. Sony includes an external microphone for optimum clarity in outgoing calls and reliable phone command requests.

The AX7000 doesn’t have built-in navigation but can use Google Maps or Waze from either an iPhone or Android device to help you reach your destination efficiently and safely, and Google Maps allows users to download maps offline so cellular coverage or data plan constraints are never an issue. Apple iPhone users can, of course, use Apple Maps should they wish.

Audio Features Deliver Great Sound

Sony XAV-AX7000The AX7000 will play MP3, WMA and AAC audio files from a USB memory stick in one USB port while you charge your phone with up to 1.5 amps of current from the other USB connection. To be specific, USB1 supports more file formats than USB2 but is also the connection dedicated to CarPlay and Android Auto. USB1 will also play WAV and AAC audio files, along with MPEG-4, WMV, MKV and Xvid video files in resolutions up to 1280 by 720 and 30 frames per second.

Sony has included its 10-band graphic equalizer to help ensure that your music sounds great. The Dynamic Soundstage Organizer (DSO) feature includes preset signal delay and level settings that help to create a realistic soundstage across the dash of your vehicle.

The radio includes front, rear and subwoofer RCA preamp outputs rated to produce 5V of signal. While the extra voltage won’t make your system louder, it allows your installer to turn down the sensitivity control on your amplifiers to reduce background hiss. Equalizer and subwoofer control adjustments are one touch away in the quick access menu from any screen.

High Power Multimedia Receiver for Unique Applications

The introduction of the Sony XAV-AX7000 provides a plethora of new installation options. This would be perfect for a Polaris Slingshot, Can-Am Maverick or Yamaha YXZ. If you want a unique infotainment solution for a motorcycle like any 2014 or newer Harley Davidson, this could be a great choice. In all instances, the extra power from the High Power amplifier is a welcome addition and since it’s from Sony, you know you can trust the radio for years of reliable performance. Visit your local specialist mobile enhancement retailer today and ask for a demonstration.

Product Spotlight: Hertz Cento Subwoofers

Cento Subwoofers

As a continuation of our look at the Hertz Cento Series, we are going to delve into the features of the new Cento Subwoofers. Available in 10- and 12-inch sizes with either two- or four-ohm voice coil configurations, the Cento subwoofers are a perfect example of trickle-down technology providing amazing value and performance for car audio enthusiasts.

Hertz Cento Subwoofer Physical Features

Cento SubwoofersThe Cento subwoofers are based on a rigid four-spoke basket. Vents in the base of each spoke allow hot air to escape from underneath the spider to provide voice coil cooling. A flat (not cupped) spider is mounted on a plastic spacer at the base of the basket. Spring-loaded wire terminals capable of accepting 8AWG wire are molded into an extension off the side of the spider spacer ring. Additional cooling is provided by vertical vents in the plastic reinforcement ring that is used to attach the voice coil former to the spider and the cone. This ring dramatically increases the glue contact area and helps to ensure each component is aligned perfectly at this crucial triple joint.

The glass fiber voice coil former has a diameter of 35 mm (1.38 inches) and serves as a home to a six-layer copper winding. The result is 300 watts of continuous power handling on the 10-inch CS 250 S2 and C2 250 S4 subwoofers and 350 watts on the 12-inch CS 300 S2 and S4 models. Based on the height of the voice coil windings and the thickness of the top plate, the Hertz Cento subwoofers have an X-max specification of 12.5 mm (one-way).

Cento SubwoofersA one-piece ferrite magnet at the base of the speaker provides magnetic flux. There is no cooling vent in the T-yoke of the Cento subwoofers, so your installer can butt them right up against the back of an enclosure without fear of affecting their performance or reliability. Speaking of mounting requirements, the 10-inch subs require a mounting depth of 4.53 inches and the 12-inch models need 5.12 inches.

The cone and dust cap on the Cento subwoofers are made from polypropylene and are attached to the outer edge of the basket using a rubber surround. An ABS plastic trim and mounting ring around the perimeter of the drive provides a clean and classy appearance once installed. Hertz offers optional protective mesh grilles with part numbers CG 250 and CG 300 to help keep the subs looking like new.

Enclosure Requirements

Cento SubwoofersHertz suggests that the CS 250 S2 and S4 will work in enclosures as small as 0.57 cubic feet and the CS 300 S2 and CS 300 S4 will work in a 1-cubic-foot enclosure. The 10-inch designs result in a system F3 of 55 Hz, and the 12-inch designs have an F3 of just under 50 Hz. For both applications, Hertz recommends implementing an infrasonic high-pass filter at 15 Hz with a slope of 24 dB/octave to prevent damage due to high excursion levels. Based on a quick look at the specifications, your system designer can use these subwoofers in a vented enclosure to provide about 4 dB more output across the board in exchange for increased enclosure volume.

Amazing Bass and Great Value

A single Cento subwoofer is a perfect match for the DPower1 monoblock amplifier, or you could match a pair of them to the HCP 1D monoblock. If you’re in the market for a subwoofer that won’t break the bank but provides low-frequency performance from relatively compact enclosure designs, drop by your local authorized Hertz retailer and ask for a demonstration of the new Cento subwoofers.

Adding An Auxiliary Input To Your Factory Radio

Auxiliary InputA message that mobile enhancement retailers strive to share is that we want you to come to us with your feature requests or ideas. If you want a remote starter or audio system upgrade, you know to come to us – but did you know we also can install heated seats, auto-dimming mirrors or auxiliary input jacks on factory audio systems? We can, and our prices are often much less than dealer options or upgraded trim packages on new vehicles. Let’s look at a few options for auxiliary input additions.

Why Would You Want an Auxiliary Input?

Auxiliary InputWe all seem to have at least few hundred of our favorite songs stored on our cellphones or portable media players. We listen to them while we are out for a walk, grocery shopping or even at our desks at work, but we can’t always listen in our cars or trucks. If your factory radio doesn’t have Bluetooth or a USB port to which you can connect your phone, then there is no easy way to enjoy your music. In addition, in many states and provinces, it is illegal to wear headphones while driving. What is the solution? We can add an auxiliary input to your factory radio.

An auxiliary input interface allows you to connect the 1/8-inch headphone jack output of your smartphone or media player to your radio. Once it is connected, you can listen to your music through the factory radio and speakers.

Optical Connection

Auxiliary Input
NAV-TV MOST AUX adapter

Many European vehicles, such as Porsche, Mercedes-Benz, Range Rover, Audi, BMW, Aston Martin, Jaguar and Bentley, use a digital fiber optic bus communication system called MOST for multimedia and audio transfer. MOST stands for Media Oriented Systems Transport. This fiber optic system handles audio signals between the radio, Bluetooth, and iPod modules and amplifiers. In many models of the vehicle brands listed above, we can add an in-line module that provides a stereo auxiliary input. No need to replace the expensive radio. Just connect to your smartphone’s headphone jack and enjoy.

Wired Connections

Auxiliary InputSeveral companies manufacture auxiliary input interfaces that mimic the presence of an optional satellite radio tuner module. The interface will have a stereo input connection for your music and will connect to your factory radio via the satellite radio tuner interface port. Just press the Sat button to activate the input.

Many older vehicles on the road had the option for a CD changer. We can provide an auxiliary input interface for many of these vehicles that allows you to connect your portable media player or cellphone to these radios. To select the aux input, just press the CD changer button.

RF Connection

For decades, one of the most popular methods of feeding and audio signal into a radio that didn’t have a dedicated auxiliary input was to use an FM Modulator. These devices would take the audio signal from your media player or phone, and transmit that into your radio via the FM receiver. You would turn the modulator on, tune to a specific radio station (which is selectable so it doesn’t interfere with a local station), and voila – you could hear your music. These are still available when a wired connection is simply not possible. The sound quality is limited by the FM receiver of your radio, but it’s better than listening to your music via the speaker built into your phone.

Visit Your Local Car Audio Specialist Today

While there isn’t an auxiliary input interface available for every make, model and trim level of vehicle, a lot are covered. Drop by your local car audio specialist retailer to see if one is available for your vehicle. You will likely want to have the shop install the interface for you – they know how to take apart the dash or remove the radio without damaging anything. And they know the best places to power the new interface. Boy, are they ever smart!

Subwoofer Enclosures, More Than Just a Box

Subwoofer EnclosuresFor decades, there has been discussion after discussion about which of the different subwoofer enclosures are “the best” and why. Let’s take a look at why we need a subwoofer enclosure at all, and how the three popular styles – sealed, vented and bandpass – differ in their design and performance.

Back-Wave Management

If you were to hook any speaker up to an amplifier, hold it in your hand and play music into it, you would find that you don’t hear any bass. That is because the sound coming from the front of the speaker cancels out the sound coming from the back. We need a way to keep the sound coming from the back of the speaker cone from interfering with the sound coming from the front. If you were to cut a hole in the middle of a large, flat piece of wood and mount the speaker in it, you would hear a lot more bass. In fact, until the half-wavelength of the bass frequencies becomes longer than the dimensions of the piece of wood, you will get really good, solid bass. If we put a speaker in an airtight enclosure, none of the sound coming from the back interferes with the sound coming from the front.

Power Handling

Subwoofer Enclosures
Different parts of the subwoofer determine its excursion and power handling.

The ability of a speaker to use the power produced by an amplifier is limited by two criteria – how far the speaker cone can move and how much heat the voice coil of the speaker can handle. Thermal power-handling limitations are based primarily on the design of a speaker – the size of the voice coil, how airflow is managed around the voice coil and the proximity of the stationary components of the motor assembly to the voice coil are the key contributing factors. The excursion-limited constraints are also part of the speaker’s design – how long the voice coil winding is, how tall the top plate is and how much suspension travel is available are the key factors.

Excursion

When it comes to reproducing bass, a speaker has to move four times as far each time the input frequency is halved. For example, a speaker moving 0.125 inches at 100 Hz has to move 0.5 inches to reproduce the same output level at 50 Hz and 2 inches at 20 Hz. You can see that, for the lowest of frequencies, cone excursion limitations are significant – very few speakers can move 2 inches without significant distortion.

When we put a speaker in an enclosure, the combination of the enclosure and the speaker create a high-pass filter. We are effectively decreasing the low-frequency output of the speaker. Why would we want to do this? The benefit of an enclosure is that we can control the motion of the speaker cone. Looking at a simple acoustic suspension (also known as a sealed) enclosure will be the simplest illustration of this explanation.

Compliance

Each and every speaker – from the biggest of subwoofers to the smallest of tweeters – has a springiness to the cone. We call this the compliance. We measure compliance by comparing it to a volume of air with the equivalent springiness. We call this characteristic of the speaker Vas. In general terms, a speaker with a very small Vas specification has a tight suspension, and a speaker with a large Vas has a softer suspension. There is a lot more to it than that, but for the discussion of enclosure features and benefits, that’s all we need to get into for now.

Subwoofer EnclosuresWhen we put a speaker in an enclosure, we stiffen the suspension. When you push in on the speaker cone, you are pushing against the speaker’s suspension (which wants to center the cone) and you are trying to pressurize the air in the enclosure. When the cone tries to move outward from rest, you are putting the air in the into a vacuum state – it wants to pull the cone back to its resting position. We do sacrifice low-frequency output, but we gain significant power handling and control over the motion of the speaker cone. For the latter, the combination of the air in the enclosure and the speaker suspension helps to stop the speaker cone from moving once an electrical signal starts it in motion.

Think of it like a shock absorber on a vehicle. You can see that having an enclosure is critical.

Acoustic Suspension Subwoofer Enclosures

The simplest of enclosures is called an acoustic suspension or sealed enclosure. In these enclosures, we are putting the speaker into an airtight box. When we put a speaker in an enclosure, the system resonates at a specific frequency that – we call this Fc. Below that frequency, the output is reduced at a rate of -12 dB per octave. If the system has a resonant frequency of 50 Hz, the output will be 12 dB quieter at 25 Hz.

Subwoofer Enclosures
Here we see the smooth response of the sealed enclosure.

Acoustic suspension enclosures are amongst the smallest of the different enclosures we will discuss. They are also the easiest to construct, and most forgiving regarding calculation error. If you combine the roll-off of the enclosure and speaker system with the increase in efficiency you get from the relatively small air volume of the vehicle interior (often called transfer function or cabin gain), you can get a very flat in-car response with good infrasonic output. Bass from an acoustic suspension enclosure is very tight and controlled, thanks to excellent transient response.

There is a down side. If you are looking for loud bass, then you need a driver that has a lot of excursion capability, and you need a reasonable amount of power to move the speaker cone back and forth to get the level of output you want. There is another drawback that isn’t talked about as much, and that is distortion. As a speaker increases in excursion, the amount of distortion it creates increases. Likewise, distortion increases near the resonant frequency of the speaker. So, what can you do?

Bass Reflex Subwoofer Enclosures

A bass reflex (also known as ported or vented) enclosure uses a vent to increase low-frequency output by making use of the speakers back-wave energy. The vent, often a round tube or sometimes a rectangular slot, has an area and a length. The specific area and length of the vent and their relationship to the total volume of the enclosure cause the column of air in the vent to resonate at a specific frequency when excited by the speaker. We typically tune bass reflex enclosures quite low to emphasize the bottom octave or so of the audible frequency range. They can be tuned higher to increase efficiency for high-SPL applications. There is always a sacrifice, though – when we tune the enclosure higher, we sacrifice low-frequency performance.

Bass reflex enclosures are typically larger than sealed enclosures. There is no hard-and-fast rule to associate with the size relationship, but 25–50% large is common. The trade-off for that extra volume is two-fold – more efficiency in the tuning frequency and more power handling, at some frequencies.

When the subwoofer used in a bass-reflex subwoofer enclosure produces frequencies around the resonant frequency of the vent/enclosure combination, the driver excursion is reduced to almost nothing and all the “work” is done by the vent. Put more succinctly, around the tuning frequency, most of the music is being produced by the vent. The benefit to this is that power-handling problems caused by cone excursion limitations are dramatically increased. Since the cone is barely moving, very high sound pressure levels can be achieved. Around the tuning frequency, power handling is limited by the thermal capabilities of the subwoofer.

As we mentioned earlier, one factor that contributes to loudspeaker distortion is cone excursion. With a bass reflex enclosure, the driver moves significantly less than with an acoustic suspension enclosure design. As long as the vent itself has enough area and a smooth transition at both openings, the distortion produced by a properly designed bass reflex enclosure can be impressively small.

Subwoofer Enclosures
Notice the rapid dropoff of the low end response (on the left) of this vented enclosure graph.

Nothing is free, is it? A factor in deciding to use a bass reflex design is how fast the output decreases below the tuning frequency. Where an acoustic suspension enclosure rolls off at -12 dB per octave, a bass reflex enclosure rolls off at 24 dB per octave. Below the tuning frequency, the vent acts more and more like a hole in the enclosure, offering increasingly less back pressure as frequency decreases. Designing for, and managing, driver excursion is a fundamental part of bass reflex enclosure design.

Bandpass Subwoofer Enclosures

We will quickly touch on bandpass enclosures to wrap up this article. There are several different designs for bandpass enclosures. Some use a sealed enclosure, and some a vented one. Independent of whether the rear chamber is sealed or vented, the output of the subwoofer plays into a vented enclosure. This enclosure acts as a low-pass filter. Why would we want to design a bandpass enclosure?

Subwoofer Enclosures
The reason for the name “bandpass” is easy to see when one looks at the response curve of the bandpass enclosure.

First and foremost, all of the output of the enclosure is produced by the vent or vents. This allows a creative designer to build an enclosure in the trunk of a vehicle and have the vent opening play through the rear parcel shelf. There have been some amazing bandpass enclosures build in the front storage area of mid- or rear-engine vehicles. The vent allows the bass to enter the interior of the vehicle. Bandpass enclosures can also offer impressive gains in efficiency over acoustic suspension and bass reflex enclosures, but they do so at the sacrifice of bandwidth and enclosure volume.

A bandpass enclosure has two resonant frequencies – one for each of the enclosures. The resultant management of cone excursion can allow a great deal of bass to be produced from limited excursion drivers. While the speaker cone itself does not move a great deal, the amount of work done by the motor assembly is still significant. You are still putting power into the speaker, and work is being done. Because the front chamber of the enclosure acts as a filter, it can also be very difficult to hear when the speaker is distorting.

Regarding the complexity of design, and forgiveness of construction error, bandpass enclosures are the most complicated to execute perfectly. Unlike an acoustic suspension or bass-reflex design, bandpass enclosure designs must be tailored exactly to the speaker they are being used with. Never trust the concept of a “generic” bandpass enclosure.

Lastly, because a bandpass enclosure includes an acoustic low-pass filter, it has to be used with good-quality, appropriately sized midbass drivers. If not, the bass can sound lost or disconnected relative to the rest of the music.

As you can see, there are many ways to install a subwoofer – or any speaker, for that matter. Navigating the available space in the vehicle, as well as different speaker sizes and designs, can be tricky. The design and construction of an enclosure can be complex, especially when complex shapes are involved.

Power Wire: OFC versus CCA

Power WireWhen it comes to high-current wiring in a vehicle, there are two types of stranded power wire available: solid copper and copper-clad aluminum. This article looks at the differences between each kind of wire, and explain the challenges of ensuring your high-current device gets the power it needs to do the job you want done.

Car Audio Power Wire: Background

Power WireIn mobile applications, or anywhere that a conductor may be exposed to movement or vibration, it is recommended to use only stranded conductors. Solid conductors (like single-strand house wiring) may offer slightly more conductor area for a given wire diameter, but over time, the solid wire can work-harden, become brittle and eventually break from repeated back-and-forth motion. Imagine using large-gauge solid copper wires in the wire boot in a door jamb or to your trunk or hatch lid. That is a recipe for disaster.

The term OFC (oxygen-free copper) has become abused and is used synonymously with solid or all-copper conductors. In actuality, OFC is a type of solid copper. When molten copper is cast and drawn into a conductor, the process to make an OFC conductor reduces the oxygen content of the wire. If all is done perfectly, the copper-oxygen content is around 42 parts per million (PPM) vs. a conventional copper with content that is roughly six times that amount.

In the mobile electronics industry, there is no way to know if the solid copper conductor you are purchasing is oxygen-free or not unless you can witness the casting process in person. Everyone in the industry uses “OFC” for a piece of wire that is not copper-clad aluminum (CCA).

Looking at the alternative, we have CCA conductors. In these conductors, the core of the wire is a cylinder of aluminum and around it is a layer of copper. From the side, it looks like copper, but if you cut off a piece and look at the end, you can see the gray aluminum content.

There are further variations. Some companies manufacture all-copper strand wire but coat the outside of each strand with a thin layer of tin to help prevent corrosion.

Car Audio Power Wire: Size

When it comes to flowing electricity, or, more specifically, flowing electrons, the most important thing to consider is wire size. In the mobile electronics industry, we use the American Wire Gauge (AWG) standard. This sets a specific diameter for a conductor. It’s not a debatable number – the conductor either meets the standard or it doesn’t.

Here is where the games begin. There is a second term used in our industry: gauge. In the steel sheet industry, gauge is an important tool for specifying material thickness. In car audio, it means nothing. If you have been around the industry for any amount of time, you will have seen wires that claim to be 0 gauge but have a conductor area equivalent to a 6 AWG. If a wire is labeled as 4 gauge, then sadly, you have no way of knowing how big it is, other than attempting to measure it.

Cutting a wire and looking at the area also doesn’t always tell the story. Some wires are wound quite loosely. This makes the wire very flexible, but does so because there is space around the strands. You sacrifice effective cross-sectional conductor area for flexibility.

Car Audio Power Wire: Materials

Power WireIn solid copper stranded wire, we ideally want everything to be pure copper. That said, pure copper is quite expensive, even though the cost of pure copper has come down over the past few years; it currently sits at around $2.00–$2.25 a pound on the commodities market. When a manufacturer wants to purchase wire, there are many options: strand count, how the strands and bundles are woven, how tightly they are woven, and so on. Manufacturers also have a choice in the “kind” of copper they make the conductors with. It could be pure copper, recycled copper or a copper alloy. Again, you have no way of knowing unless you are witness to the process.

Don’t let the variations in copper scare you. A solid copper conductor always outperforms a CCA conductor. The biggest challenge with car audio CCA wiring is that it does not, and will not, specify the ratio of copper to aluminum. There are publicly displayed measurements of different CCA wire samples where a smaller-diameter wire outperforms a slightly larger wire because it has less aluminum and more copper. Unless you measure it yourself, you just don’t know.

On its own, pound for pound, aluminum has about 60% more resistance to the flow of electricity. When we talk about CCA wire, there is some copper in there; in most cases, the difference diminishes to 30 to 40%.

Car Audio Power Wire: The Challenge

Power Wire
This Audison Connection Power Kit Features OFC Copper wire.

When you look at car audio wiring, there is no way to know what you are getting with a CCA amp kit or roll of wire. Some manufacturers make CCA wire that functions nearly as well as solid copper. In fact, one company makes an oversized CCA that has less resistance per foot than solid copper. The downside is that the wire doesn’t fit into a lot of connectors or terminal blocks. Overall, unless you want to take the time to measure the properties of the kit you are buying, it is better to stick to solid copper.

From the standpoint of long-term benefits, solid copper wire resists corrosion much better than CCA wiring. In climates where road salt or brine is used in the winter to keep surfaces clear of ice, we have seen instances where unprotected CCA power wires have failed completely in less than two years. Why risk the performance of your audio system, when you can simply choose the solid copper wire?

How do you know if you are getting something good? The Consumer Technology Association (formerly the Consumer Electronics Association) has developed a standard for wiring. It is called CTA-2015 (formerly CEA-2015) specification. It describes the minimum standards for wiring for use in mobile electronics applications. The standards include that the wire must be stranded solid copper, the minimum number of strands for a given AWG wire size, and the area of the wire and its maximum resistance. If you stick to the brands that support the CTA-2015 standard, you should never have any problems.
