i had 2 rockford 15 xlc's too with a 1200w(600rms) amp in my trunk, of course the thingy that stretches accross the trunk was taken out, just use a hatchback box(standard box) and mount the amp on top of the box, word of advice though.. Im not sure if your integra has the carpet that is on top of the plastic that is over the spare tire, but your speakers will cause the carpet to move around alot.. solution: drill self tapping screws through the carpet at the sides into the metal, or else your shiz is gonna be allll over the place...
