so i have an aftermarket cd player installed in my fc, but every once in awhile the sony speakers (aftermarket) in my door will shut off and no sound can be heard from them, the speakers under the dash and in the rear towers still work fine though. anyway anyone know a way to fix this so that they arent shutting off everytime i drive??

 

Sounds like you just have a connection problem somewhere. Check your wiring from the deck all the way to the speaker.
