Here’s what it includes:
- Front tweeters
- Front midranges
- A center midrange
- Underseat woofers
- Rear midranges
- Rear tweeters
- Side “effects” midranges
- Nine-channel optically-driven processor/amplifier with front/rear/woofer/center/side outputs
- Equalizer and “Surround” settings controlled via the head unit’s menu
The amplifier doesn’t have an analog input – the signal is derived from the MOST fiber-optic network in the car. This is what has made upgrades to this system more difficult than in other systems.
Musicar Certified Sound systems for this vehicle use a MOST-to-analog D/A converter, which provides us with 8 channels of flat, full-range, unprocessed sound, retains front/rear fade, and retains the OEM equalizer function. The “Surround” feature is deleted (thank goodness) and the center and side speakers are no longer supported (nor are they missed). We also upgrade the most important speakers, and replace the amplification. The stock head unit is retained and all functions besides the “Surround” button work just as before. All the new gear is plug-in and bolt-on with zero modifications required, and no vehicle reprogramming needed.
