clarion dxz635mp no sound

I had this unit installed a few years ago and everything worked fine. I went out of town last week and left the car in the airport parking lot for 5 days with a sunscreen in the windshield. Now the unit looks like it plays but no sound output. I've pulled the face off and reset the system but still no sound. It appears to tune to new stations and it read Cds, MP3's and WMA's. Everything looks normal except for no sound. Could something have melted? The highest temp the week I was gone was 95.tunester63

When you got back from the trip, was your battery dead?     Are your speakers connected to the head unit, or do you have amplifiers for all of your speakers?  I am sure that Mobile asked what kind of car so we can figure out if your car has a factory amp that is in use.

It's a 92 Honda Accord. Battery was fine and everything else on the car works as it should. The speakers are connected to the unit. I didn't change out anything except the unit itself from the factory cd player.tunester63

It could be the deck that went bad, or possibly even speakers. I'm not sure about the Clarions, but alot of decks will go into a protect mode if a speaker is blown or grounding out to prevent the amp from frying out. I would do what idiot said, and get the deck tested. It will be a good starting point.

It turns out one of the speaker wires had a loose connection and the wire was touching bare metal. A new connector is on and it works fine.tunester63
