I just put a pioneer deck into a 94 mustang convertable with the premium sound and only the right speakers work but I have it wired right, and ideas on what to do??

[bgt98]

did all the speakers work before you installed the pioneer deck?

are the speakers wired to the aftermarket head unit's amp?

Check the speaker balance on the deck to make sure the left side are turned on.

there is a small amp behind the radio you have to wire after the radio uses common grounds going into the amp
