Do you have any picture somehwhere?
I have lots of pictures, but they are not posted anywhere. I don't have a website or anything (I'm convinced this internet business is just a passing fad and making a website would just be a waste of time) and in any case the pictures I do have are now obsolete as I have completely re-done the system. I am now running a separate class-T amplifier for each one of my five channel pairs, with remote gain controls built into the center armrest for each amplifier, along with a 30-band (1/3 octave) stereo equalizer.
Right now it sounds really terrible, embarassingly so, I have picked up an alternator whine that I can hear quite well with the stereo playing loud enough to listen to at 70 MPH. Gotta be a ground loop -- but with 5 amplifiers, two head units, a Sony switch, an equalizer, and four passive crossovers between my battery and my speakers, it's not gonna be easy to find.
