A friend of mine just picked up a 1997 Chevy blazer well the problem hes having is hes getting no sound out of the speakers.He replaced the stock radio with an alpine head unit every thing turns on no sound out of the speakers put the stock radio back in everything turns on seeks through the stations but still no sound no static absolutley silent i checked all wiring antenna wire fuses they were all fine i even changed the fuses for shits and giggles does any one have any idea what this could be your input would be much appreciated
maybe someone had an aftermarket (amplifiers) system in it & none of the speakers are connected to the head unit harness. Try ‘popping’ the speaker wires with C battery (+ to speaker +, - to speaker - in the head unit harness). if you get a sound from the speaker (clicking), then the wires are connected to the speakers. If not, you may want to pull one of the speakers to see if connected.
thx alot
