im not really bragging but for anyone wanting to put a killer system in their car, i have found an awesome set up. i installed a kenwood deck (dont remember the model right off hand), two profile ap1000m amps, and two alpine type r twelves in a ported box. they hit sooooo hard that they scoot the box backwards. this is with just the gain turned up some on the amps and the bass boost and all of that jazz turned all the way down. just thought i would share what was working really well for me
