The power ratings on car audio source units have been over-rated for years. Claims of 40, 50 and even 55 watts per channel are emblazoned across the front of radios in an effort to one-up competing products for the title of “most powerful” source unit. Sony recognized the need for a true high-power solution to provide music enthusiasts with the listening levels they want. The answer to this need was to debut two source units at the 2015 Consumer Electronics Show that redefined how much power a source unit could produce. Let’s take a close look at the Sony Hi-Power source units.

True Hi-Power Amplification

The MEX-XB100BT and MEX-M100BT radios are rated to produce 40 watts per channel. Independent test labs measured the actual output at a respective 43 and 43.7 watts per channel using the CEA-2006 process. With most conventional source units providing between 18 and 20 watts of real-world power, the Sony solutions represent a significant, clearly audible upgrade.

The second generation of hi-power Sony source units includes the MEX-GS820BT and the WX-GS920BH receivers. Using what Sony calls the Dynamic Reality Amp 2, this latest generation of source unit provides a very impressive 45 watts per channel of clean power to drive your speakers. This yields an impressive 180 watts total RMS power.

Why is Power Important?

It takes power to reproduce sound. For every 3dB increase in output from your speakers, your amplifier needs to provide twice as much power. It’s easy to imagine how quickly you can use up the 18 watts in a typical source unit. Especially when you are trying to overcome road, wind and tire noise in your vehicle or attempting to rock out to your favorite music.

Sony wanted to provide its customers with a cost-effective solution to get the power they want without the (relatively) significant expense of adding an amplifier to their system. Combining their engineering knowledge with the latest Class-D amplifier technology, Sony put together a series of hi-power solutions that fit into a standard radio chassis. Functioning the same way as a stand-alone amplifier, Sony Hi-Power source units feature a dedicated switching power supply to increase the voltage available to feed the onboard amplifier, and subsequently, your speakers.

The Benefits of a True Hi-Power Source Unit

The popularity of Sony’s Hi-Power receivers has been impressive. With both marine and automotive solutions available, adding the performance of a hi-power source unit to motorcycles, UTVs and pickup trucks that have limited space is easy. There’s no need for RCA Interconnects or large-gauge power wire. Moreover, you save on the additional installation time required to install those components and an amp.

Sony didn’t skimp out on the amplifier either. You can drive 2-ohm speaker loads on all channels to increase output even more. Using the Subwoofer Direct mode, you can power a sub with more than 90 watts of real-world usable power. If you are building a system one step at a time, this is the perfect starting point.

Additional Source Unit Features

All Hi-Power receivers are equipped with front, rear and subwoofer preamp outputs rated to produce up to 5.0 Vrms to drive external amplifiers for even more fun. Sony’s Advanced Sound Engine processing includes digital signal processing to let your installer time-align the output to create an amazing soundstage. A 10-band equalizer is also provided to assist with creating smooth and realistic frequency response. Mega Bass (found on the original hi-power source units) and Extra Bass on the current models let you boost low-frequency output at lower volume. As you increase the volume, the boost diminishes to prevent damage to your speakers.

You can enjoy all the detail and realism of high-quality FLAC and WAV audio files from a USB stick. Or pair your phone and stream your favorite tunes over a streaming connection with Sony’s high-end Bluetooth technology. Speaking of connections, the SONY | Music Center system allows you to hide your source unit in the glove box, under a seat or in the trunk and still be able to control the radio using your iPhone or Android-based smartphone. If you are looking for the perfect source unit for a custom car or hot rod, Sony makes it.

Sony also includes a steering wheel interface to ensure your new radio is easy to use. All of these source units feature an external Bluetooth microphone for exceptional outgoing phone call sound quality.

Early in 2017, Sony launched its XAV-AX100 multimedia receiver with Android Auto and Apple CarPlay to rave reviews from retailers and consumers alike. Sony is taking its smartphone connectivity solutions to the next level with the introduction of the new XAV-AX200SXM. This unit builds on the performance and reliability of the XAV-AX100 and adds new features to appeal to even more consumers.

Smartphone Integration Technologies

The XAV-AX200SXM includes Apple CarPlay and Android Auto. These smartphone integration solutions are designed to allow you to listen to and dictate responses to text messages, make phone calls and choose the music you want to enjoy by simply talking to your radio. Streaming music, turn-by-turn navigation with real-time traffic information and instant access to the music on your phone is as easy as asking for it. The CarPlay and Android Auto features bring your phone’s approved apps and content to your dashboard for quick and easy use while driving.

Audio Source Options

The XAV-AX200SXM includes a CD/DVD mechanism to let you enjoy your favorite artist or watch a movie or TV show when you are parked. The USB port on the rear of the chassis will let you play MP3, WMA, AAC and FLAC audio files as well as MPEG-4, H.264, WMV, FLV, MKV and XviD video files from a memory stick. Sony has graciously included a SiriusXM satellite radio SXV300V1 tuner with the unit. You also receive 90 days of free SiriusXM service so you can enjoy your favorite programming from coast to coast right out of the box. The built-in AM/FM tuner includes RDS information display, and you can stream music from your smartphone using the Bluetooth connection, and control Pandora and Spotify as well.

System Connectivity Options

One of the coolest features of the XAV-AX200SXM is its triple camera input. Your retailer can add a dedicated backup camera, a blind spot monitoring camera on the side of the vehicle, a parking camera in the front grille, rear seat monitoring for small children or a hitch camera for trailering. Tap the Camera button in the menu and choose the view you want. The backup camera image appears automatically when you put the transmission in reverse.

A built-in four-channel amplifier provides 20 watts per channel of CTA-2006 certified power with up to 55 watts per channel of dynamic power delivery to bring your music to life. Three pair of 4 Volt preamp outputs with Subwoofer Level Control makes it easy to upgrade your sound system further.

Built-in high- and low-pass crossovers work on the internal amplifier as well as the preamp outputs to optimize the signal for your chosen speakers. A popular example of the benefit of built-in crossovers would be the addition of a subwoofer and an amplifier. The built-in crossovers will let your installer filter out the low-frequency information being sent to the internal amplifier to improve the clarity, detail and output from the smaller speakers in the system.

Sony has included a 10-band graphic equalizer to let you fine-tune the performance of your system. The EQ includes preset curves, or you can make adjustments on your own. The Dynamic Soundstage Organizer helps to improve front soundstage imaging in the vehicle.
