first off, i already have 2 12" kicker comps. i have a 2002 chevy avalanche. at the moment i put my subs in the middle seat in the back, turned sideways and facing up so i only lose one seat. i was looking to add two 15" subwoofers into a custom made box to go behind the seats, i know they make them, i've seen several on the internet but im not able to find a square one for two 15s. if you find one please post the link. ive found some that are circles, and if i have to i will get them. what would be a good amp to power two 15's? i was thinking that i would have to buy another car battery and hook up the amp to it. any tips on anything would be helpful. my friend also told me it would sound bad to have two 15's and two 12's so should i keep both or sell the 12's. also, i need some help with the wiring if i had two amps and such, to be honest i dont really know very much about any of this stuff. any other information i missed please let me know and ill answer anything. thanks! =]
