It 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

In 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?

Whether 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

So, 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 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 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

With 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.

Not all that long ago, upgrading the performance of your car audio system required that you replace the factory source unit. The industry had dozens of premium CD receivers with state-of-the-art signal processing and high-end digital-to-analog converters. The popularity of these source units and the audio systems that could be built around them was not lost on automakers.

Slowly, technologies like Bluetooth audio streaming and hands-free calling, USB support for digital audio files, and direct smartphone control have become the norm when you purchase a new vehicle. On the audio side of things, automakers have partnered with companies like Panasonic, Bose and Harman to provide expertise in configuration and tuning to elevate the performance of factory-installed systems dramatically.

If you go shopping for a new vehicle, you may notice that the radio is no longer a single component in the vehicle. Some manufacturers spread audio control and information display across three locations in the vehicle. Replacing the radio simply isn’t an option in many applications.

For those of us who want to upgrade our sound systems, the philosophy and process have changed a great deal. If we can’t replace the radio, can we get great sound? Thanks to ongoing research and innovation, the answer to that question is a resounding “yes.” Let’s look at how this is accomplished.

Fix What’s Broken

The source unit in a modern vehicle usually has most of the features and functionality we need. Smartphone integration solutions like Android Auto and Apple CarPlay, well-tuned Bluetooth hands-free, and a backup camera are very common. Where most audio systems suffer is in the amount of power they have available and the speakers.

Not having enough power means that when you turn the volume up past a certain point, the signal begins to distort. Not only does this sound bad, but it delivers additional energy to the speakers and can damage them. It has been said that you can never have too much power. In terms of ensuring the signal going to the speaker is clean and undistorted, this statement is perfectly true.

The second issue is the speakers that automakers use. Even in premium branded systems with names like Lexicon, Bose, Boston Acoustics or JBL, the speakers are, at best, mediocre. Sure, there are some exceptions, but on average, they lack the accuracy, detail, excursion capabilities and power handling of a quality aftermarket speaker.

If you want to improve the performance of your factory sound system, add more power and have better speakers installed. The recipe is really just that simple.

The Steps to Success

The first step your local mobile electronics retailer will take is to determine how best to integrate with the factory radio. In some cases, this is as simple as connecting the speaker wires from the back of the radio to speaker-level inputs on a new amplifier. If the factory stereo system includes an amplifier, then a line level converter may be required to reduce the voltage to something that the new amp can use properly.

If you have a more-advanced factory audio system that includes equalization, crossovers and signal delay, the integration process requires hardware between the factory amp and your new high-power amplifier. Several companies have developed processors that will undo much of the tuning built into these amps and provide a full-bandwidth signal that your installer can use to build the new system.

Another option is to use a factory amplifier replacement module. These devices accept the audio signal from the radio and, in most cases, capture volume control information from the vehicle’s CAN bus. The output of these replacement modules works just like an aftermarket radio – we have a full-bandwidth signal that can be used to drive new amplifiers.

Advanced System Integration

At the highest levels of factory audio system integration are systems that include upmixers. An upmixer is a device that takes the stereo audio signal from your radio, iPhone or CD and converts it to multiple channels. In most cases, this includes left, center, right, left rear, right rear and subwoofer signals. Why do automakers implement upmixers? When tuned properly, your music will sound great from every seat in the vehicle. Both the driver and passenger will hear a performer recorded at the center of the stage from the middle of the dash.

To integrate with these systems, it’s often best if we keep the factory signal processing in place, then add a digital signal processor (DSP) between the factory amp and the new high-power amplifiers. The DSP lets us fine-tune the frequency response of the system so the new speakers can produce an amazingly accurate and lifelike listening experience.

Speaker Upgrades

As we mentioned, it is important to upgrade the speakers in your vehicle to achieve an overall improvement in sound quality. Premium speakers provide smoother frequency response, extended bandwidth (they play lower and higher in the frequency spectrum), increased power handling and louder volume. If you are going to add amplifiers, then it only makes sense to ensure your speakers will be able to make use of that newfound power.

Speaker shopping can be somewhat difficult. Listening to speakers on display boards doesn’t always provide a sense of what those speakers will sound like in the vehicle. A close look at the speaker design, research into the brand’s reputation and a thorough understanding of speaker technologies may prove to be a better way to shop.

One problem with this approach is marketing. No matter the quality of a new speaker, every manufacturer wants people to think that their products are the best. Filtering the genuine features from the marketing fluff can be difficult. Work with your retailer to find a solution that sounds great, fits your budget and works with your application.

System Installation

If only installing mobile electronics equipment were as easy as setting up a new microwave. We can’t simply plug it in and turn it on. Wires have to be run, connections have to be made and equipment has to be mounted. Budget for these requirements before you go shopping. The performance of a new speaker in your vehicle depends as much as on how it is installed as on its design.

If you are changing speaker sizes, you will want plastic adapters instead of wood to eliminate the chance of damage due to water infiltration. You will want high-quality interconnects to ensure noise can’t creep into the system. You will need large-gauge power wire to deliver current to your new amplifiers efficiently. Talk to your retailer about the products and processes he uses.

It’s Not Over Yet

The last step of the installation process is to tune the system. Even the addition of a subwoofer requires proper tuning. The installer should confirm that the output of the sub is combining acoustically with the rest of the speakers in the vehicle. The sensitivity of the amplifier should be set so the systems have excellent overall balance and won’t distort when the volume is turned up.

At the top end of the spectrum, systems with new DSP units require that each channel of the sound system be tuned to provide smooth frequency response. Having the right channel a little brighter or more laid back than the left will cause the location of a performer or an instrument to seem to move around the vehicle as its frequency content changes. We want everything to be stable and naturally balanced. Budget for at least an hour or two of tuning to ensure you are getting everything you can from your upgrade.

Enjoy Better Sound

Upgrading your sound system with new amplifiers and speakers is a great way to increase maximum volume, reduce distortion, and improve imaging and staging. The process most certainly doesn’t require a new source unit, but it does take some planning. Work with your local mobile electronics retailer to design an upgrade for your sound system. The experience will truly let you enjoy your music in a way you have never heard before.

When it comes to reproducing an audio signal, your speakers are the most important component in the food chain. You could have the best source unit and amplifiers known to man, but if your speakers are mediocre, then the listening experience will suffer. That said, the world of car audio has changed over the years. With all of the changes in new cars lately, a question that often comes up is “Will upgrading my speakers make my stereo sound better?”.

Factory Audio Complexities

Spurred by the efforts of companies like Harman and Bose, factory audio systems sound better than ever. Does that mean they sound great? Not necessarily. OEM audio systems have amazing technologies and elaborate tuning, but they are often missing a crucial component – excellent speakers. Why go to all that trouble and not use the best speakers possible? In most cases, the answer is cost. Building an inexpensive speaker may cost $20 or $30. Building one that is “really good” can cost more than 10 times as much, and it goes up from there. These prices don’t include packaging, shipping, marketing, training or warranty costs. When you consider that most cars with premium sound systems have somewhere between 12 and 20 speakers, with a few having more than 30, implementing truly excellent speakers would have a dramatic effect on the final cost of the vehicle.

How About Just Upgrading My Speakers?

If you had a high-end, two-channel home audio system, upgrading your speakers would be one of the easiest ways to improve the clarity, detail and accuracy of your audio system. If you have a simple stereo system in your car, the same philosophy holds true.

There is a problem, though. More and more factory audio systems, even systems without elaborate amplifiers, include signal processing to make the inexpensive speakers they use sound better. Let’s look at an example.

Chrysler is well known for its use of a woofer in the front door of its vehicles and a small midrange driver on the dash. In most applications, this midrange driver has no tweeter. The amplifier in the car or truck is tuned to increase the high-frequency information sent to that speaker. The result is that you hear high-frequency content in a relatively good balance with the midrange information.

Let’s say we upgrade those dash speakers with a good quality midrange speaker with a coaxial tweeter. The high-frequency signal boost from the amplifier or source unit now results in far too much treble information in the system. Yes, we upgraded the speakers, but now the system sounds worse. In fact, it may be unlistenable.

The same issue exists with any speaker we want to upgrade. Adding a subwoofer, better door speakers or new speakers in the back of the car can all result in a system that doesn’t sound as good as the factory system. Every speaker has different efficiencies, frequency response characteristics and frequency limits. Assuming you can swap one for another will lead to problems.

How Do We Upgrade Our Sound Systems?

Without getting into the complexities of sound systems with upmixers and other elaborate processing, the simplest method of upgrading is to include a digital signal processor and amplifier into the system. Here’s how this works.

Your mobile electronics retailer will install a digital signal processor, a new amplifier and your new speakers. He or she can then measure the output of each new speaker using a real-time analyzer and adjust the processor it so that it produces smooth and natural frequency response. The process should take just an hour or two, but it results in a significant improvement how the system sounds. Proper tuning is as important as the choice of speakers and their installation.

With most DSP units on the market, the tuning process can improve the frequency response of the system – and where the sound comes from. Ensuring that both left and right speakers sound the same at the listening position is crucial to creating the feeling that your music is coming from a soundstage right in front of you.

It’s Not Just Your Stereo

Your speakers are not the only part of your vehicle that has become more complicated to upgrade. Decades ago, a set of headers and a large diameter, free-flowing exhaust could unleash a noticeable increase in performance. Your mechanic could fine-tune a carburetor to increase engine performance based on the efficiency improvements you chose.

With modern computer-controlled engine management systems, you can’t change anything. If you decide to modify the intake or exhaust, the computer may not like the changes and turn on a Check Engine light. The solution? A programmer can be purchased to recalibrate the engine management system for the modifications you have made. Do you see the parallels?

Upgrade for Better Sound

The answer to the question of whether upgrading your speakers will make your stereo sound better is a resounding yes. But the overall system design needs to be taken into consideration for the upgrade to be successful.

If you’re on the fence about upgrading your audio system, drop into your local mobile electronics retailer and listen to their demo vehicle or a set of high-end speakers on their display board. Ask if they can demonstrate how digital signal processing can improve the performance of a mobile sound system. Once you’ve heard how amazing a well-installed and properly tuned car stereo can sound, we think you’ll be hooked.
