Yeah, a lot of work went into the system that was built and designed by me, using B stock Nakamichi equipment. I fabricated mounts for a second alternator (chromed GM alternator of all things) and a dedicated second battery in the hatch of the Honda. On the score sheet, I had a perfect score for system noise. I even installed a fairly large capacitor in the engine bay to get rid of the "ripple" voltage in the system - the last bit of noise in the system. For low end, I used two 8 inch Pyle subs in a clamshell, isobaric configuration. "Smoothest sounding bass I have ever heard," said one judge. I entered into the sound quality competition rather than SPL. My imaging was spot on and my RTA scores were pretty decent, considering the problem with standing waves due to the physical properties of the car. The amps were in an amp rack made out of half inch, clear acrylic. The amps looked like they were floating in air. Side mounted computer fans to dissipate any heat from the amps. I had passive crossovers and rear speakers hidden in the rear shelf. The custom built passive crossover for the front speakers were in the glove compartment. The crossovers were built so you could readily change the caps and coils. The speakers were all Nakamichi. Again, B stock. Centre channel speakers were hidden behind the centre air vents. The system was completely independent of the car's electrical system and was turned on by the cigarette lighter. The front tweeters were in the corners of the dash, mounted in air drying clay and covered with speaker cloth that matched the interior. I remember stripping down the car to bare metal. The front dash was taken out completely. All this was done in my garage. The installation was not the bulk of the work. It was the tweaking of the system that took countless all nighters. I had an Audio Control EQL to fine tune the system. First by ear, then off to any car audio shop that would let me use their RTA to get it perfect.
