what do you mean by *sub gets a feedback* can you give more details?
"feedback" term is used for some sort of oscillation, as in the high pitched screetch when you get microphone feedback.
Is it a constant sound? rumble? Does it happen at all volume levels? When all doors are closed? what if one door is left open? What if doors are closed but windows are open? Or is it a noise in the sub only when you close a door? all doors? one door in particular?

please help us!
Also find out if your car has some sort of interior noise cancellation system. If it does this could be the problem. It uses the existing soundsystem to cancel noise. Adding a sub would interfere with the system...
