I am runnin 2 mtx thunder 15's and a rockford fosgate bdpower 500 amp. It started makeing alot of weird noises... but when i move the cd player around it stops. I dont know if its engine noises or what. It just started doing that. I have the speakers bridged to each other. What could be making those noises? It kinda sounds like i got a nice exhaust sound but when you turn the radio off the inside of my car is real quiet. its pretty damn annoying.
