the other day i took a hard turn and my speakers cut out, but the sub still plays the bass in the song. about an hour later it was fine. today i took another hard turn and now the speakers wont play and the sub still plays fine with the songs from my ipod. i took out the deck and checked all the wiring in there, checked at all 4 speakers and it looks ok, but none of em play. i have kicker ds600s on doors and rear deck running off the deck and the sub in the trunk is amped, the only thing i can think of is that i blew a fuse but where would it be? and why would the sub still work and the deck still functions fine. just no sound from speakers.
