ok so this isnt in a car but I installed a car stereo in my camper since it had no radio. the original dual head unit i put in was an old unit that used to be in one of my cars and it worked great. then i went to turn it on one time and got no sound.
so i got a newer deck and installed it, same issue. the speakers are good. I have pretty much come to the conclusion myself but wanted to make sure that what i think it is, is what it actually is.
I want to say its the antenna, would it be possible for an antenna to kill the audio part of a stereo? all my wiring is in good condition, the unit still powers on just fine, just NO sound.
