C6 Stereo Replacement


There is too much to list to go into all the details, so I will just hit the major points:
- The entire interior of the car including the dashboard was removed to bare metal/fiberglass, and every inch was covered in Dynamat and then DynaLiner. This resulted in the car being almost 8dB quieter on the freeway at 70mph. Eight dB is a huge gain in the audio world.
- The Audio system was designed to be removable, and the car put back to stock if need be.
- I used a Pioneer AVH-4200NEX for the head unit. This radio has compatibility with Apple Car Play and Android Auto. It also has very good audio performance, customizable screens, and inputs for two cameras.
- The Pioneer drives the inputs of an Arc Audio PS8 DSP processor that allows me complete control of the tuning and adjustment of the audio signal to each amp channel individually.
-The output of the PS8 goes to a XDi 1200.6 that drives the Mid-bass woofers in the doors, 4" mids in the doors, and tweeters in custom made pods integrated into the windshield pillars.
-An Arc Audio XDi 1100.1 drives a 12" Audiomobile woofer in a 2.2 cubic foot sealed enclosure.
- The front speaker system is a three way Elate component setup from Morel. The doors house a pair of 10" mid-bass woofers, and a pair of 4" mids. The tweeters are mounted on the windshield pillars and laser aimed to improve the car's soundstage.
- The subwoofer enclosure was custom made of MDF and fiberglass, and shaped to allow the roof to still be stowed. The woofer fires downward and towards the rear of the car.
The entire battery harness was replaced from the alternator to the starter and the starter to the fusebox, and the fusebox to the rear mounted Red Top Optima battery. I used 1/0 high strand count oxygen free copper cables, which have less than half the internal resistance than the OEM 4 gauge cables.
- The car has been featured in several different booths at SEMA, and the system gets rave reviews. It is seriously one of the best sounding car systems I have ever heard, and I've been doing this since 1976.
It does not play stupid loud, but you hear every nuance and every note with exceptional clarity, even at triple digit speeds.
The car also got front and rear radar detection, Lidar shifters, front and rear proximity sensors, and a rear view camera, in addition to other odds and ends.

Here are a few photos of various stages of the build:
Every speaker is mounted using machine screws.
Every wire is soldered, and treated to color coded heat shrink.
Amp rack - needs a good dusting! Cooling fans tend to draw in dust.
Pioneer radio with custom splash screen.
Subwoofer enclosure with edge lit plexi Grand Sport logo.
Radar head, and dual USB ports in ashtray. Door still operates normally.
