My 07 GT with the Monsoon Stereo has two problems. The constant feedback through the speakers which from searching the forum sounds like a bad ground somewhere. Not sure if you'd call it feedback but it's a constant light static sound even when the car is turned off.

It also sounds like the front speaker may be blown. Does anyone know how hard is to replace the front speaker? Also if there's an easy fix for the background noise or what exactly to check that would be great.

At this point I guess I'll just pull the stereo and check connections to see when the sound goes off. Would adding another ground possibly help?
