i put door hinges into the rear backseat to the subs. i found out that putting in the center has a better sound then putting on the side. you will notice that the size is on one corner than the other. when i first got my subs, i didn't hold it down so it was running everywhere. when it was facing on the left side, you could hear the music on your right. i know it's weird but the sound bounces from the wall. and i put my amp under my passenger seat. since it slopes down alittle which i would want a little venting area which works best for me. wiring is pretty simple. power, RCA (music from headunit), and remote wire which when you start your car, your amp will turn on. if you need help, post the problem here. the hard part for installing is hiding the wires. everything else is easy.
