I decided to put my 2 12's on my sony amp in the back with my 15 and another amp on it. Wich i should have never done. I took the 12's out and my 15 seemed to be alot quiter. Really quiet like you cant here it. Now when i hook my 12's back up the sound like they are out of phase. I changed amp's on them and they do the same thing. So then i hooked my 15 back up and it does the same thing. What is the problem it makes a wierd boing noise when it hits and it also cuts out . I have never had this happen b4 what do i need to do. Forgive me if this is a noob question.

question #1: why do you feel it nessicary to have two 12"s AND a 15"? the frequency response overlap is huge and personally i don't see how you'd gain from that setup

question#2: do you have adaquate power/ground wires? the addition of another Sub amp is a tremendous strain on your electrical system.

Don't mix sub sizes. It'll sound terrible and cancel out. Have the correct sized power wires and ground wires, scrape the paint off the place where your ground wire is bolted to the frame.
