i have a 1990 twin turbo i bought and only the front center speaker is working i have checked fuses and connections but all appear to be tight i would like to keep the same stereo but will go to after market if it is something major
thanx

 

each speaker has its own amp from what i believe but im not entirely sure but that could be your problem or maybe one of the connectors in the back of the stereo face came loose who know but check out your amps and hopefuly you will find it good luck and i hope everything works out for you
