Why does my Pioneer stereo not produce any sound?

"Sounds like you might have blown the amplifier in the deck. Hook the RCA outputs into an external amplifier of some sort and see if there is sound there.

Also, I second markus on check all the wires. Plus this time before you put it back in be sure to cover all non used wires with tape or something to prevent shorting. The amplifier turn on wire shorting for example has been the cause of many blown decks."

"hi, i've looked around a little bit

it could be blown power amp but it could also be a cable problem

if a cable speaker is shorted to ground or (in your case) the short was on the casing the radio mutes the output to save the amp

remove all cables and put them back to the radio - connect the speakers one by one to see if it works or mutes again"

"This is what I would do given the information! Some wiring in cars do not hook directly into aftermarket stareos. Check with a spair speaker to see if your deck is working. If it is, then the problem is in the wiring to the car and you mmost likely need another adapter. If you had sound before the spark, then it is most likely your amp. In this case, include an amp into your sstereo configuration and problem solved.

note, some car audio has power amps built in and can have blown/burnt fuse due to the spark, however unlikelydon't forget about that"

"which Ic using for power amplifier?

there is a luck test ... if the ic is not blown but not powering on , then take a relay (12v) connect one side of relay coil to deck grount , and next coil just touch and release to vcc pin of amplifier ic , the relay makes a 'tick' sound , as it produce some back emf there is a possibility of switching it on , in my case it works .. I has the same prob with my chevorlet inbuilt radio..."

My pioneer radio does not have front and back speakers settings and it has leftband right
