This was one of the award winning cars that was built by SpeakerWorks out of Orange, CA. My current Audi was modelled after this car.
After Harry retired, he sold it to SpeakerWorks and then they used it as a shop demo car for 4-5 years. Afterwards, they sold it to a gentleman from TN.
I managed to buy it from Ryan and it is now being restored by Jeff Smith of Audio Designs of Atlanta.

Here are some pictures from before I picked it up and drove it down to TN.

Picture of the Exterior

The rear window. Yes, that is paint.

Here is the trunk. Notice it is shaved and the lockign mechanism has been removed.

Driver's Side. Again, notice the hand painted logos.

The Famous Trunk. It lost less than 10% of usable trunk space.

The USD Signal Processors

OLD Crossfire Amps with Plexi cover.

Spare Battery for Sound System and Bank of caps.
