I just installed a factory radio in my 93 MTX that i know works good, but i can not get any sound from any of my speakers.I tested the radio in my 95 ATX and it worked great.I have checked my amp in the trunk and it also works good and i am getting power from the radio to the amp.The car did not have a radio in it when i bought it so do you think all the speakers are bad? I did have to replace the cable running from the radio to the amp but i have double checked it and it is plugged up.Does anybody have anything else in mind that i might want to check?
