the ed amps are bridged, one for each front channel, so only 1 rca per amp, that rack is not an extra box, it is two boards held up by L shapped brackets made of mdf mounted to the back of the sub box. and to fit a 3.5 cu ft net box in there, i had to cut some sheet metal where the seat folds down, then great stuff, then fiberglass, then carpet. i will fix the doors, i like the idea about making a cover panel with a logo, maybe out of vinyl... and the amp rack is up so high because a hc2400 is below it, so it could not go any lower
