Default Radio POP sound

Hi guys,

I need some help with a radio gremlin that has surfaced in the last two weeks...

The radio will occasionally make a loud pop sound thru the speakers, and sometimes the radio will go silent for a few seconds or the volume will drop off. After I noticed that tapping the bezel will bring it back, I began to wonder if something has come loose inside the unit itself???

I have the CD-EQ am/fm job in a 92 Coupe...anybody got any ideas what to look for? If I pull the unit, are there any components inside notorious for coming loose?

Hey Mark, the radio problem probably stems from your hack wiring job jumping the 2 popup headlight motors together, LOL

The popping sound and subsequent volume changes sounds like a short in the amplifier section of the unit. Since radios today are solid state, it's probably less likely that something has come loose on a circuit board, but that it's a bad transistor, resistor, capacitor, etc. -- I've been told that these parts can become intermittent, without dying altogether. I have a similar problem with my home theater receiver, but it's with only the left channel.

You could pull the unit to be sure the harness plug is secure, but I doubt that's it. Since your car is a '92, the unit has probably just seen it's usable life, and it's time to upgrade.

Check this thread out. Maybe RobK can cut you a deal on a factory unit for a 92, or maybe the 93 is the same unit:
