1996 Stereo Issues

[danny3221]

I have a 1996 xlt with preminum stereo, Suddenly , I no longer receive audio, all other components ( clock, cassette, digital displays, etc) work, but I get no sound. I have checked all the fuses that I can find, I have replaced the amp (the one mounted on the passenger's side rear) but still nothing.
I thought it might be the radio itself, I replaced that with two different ones an OEM and an after market one. still no sound, I have 4 speakers, they all seem to be in good condition. Is there a fuse somewhere else that plays in on this???

If not, does anyone have any suggestions for a remedy

Any good solutions out there??

Can you check to see if the remote turn on for the OEM amp is working? I think it's only 5V.

Is the premium amp driving only the sub or all channels? It would seem to be all channels. Grab a multimeter and see if that turn-on voltage is present as toypaseo mentioned, and see if power (12V+, red wire usually) and ground (black) are present on the connector to it. There is a fuse for the amp, but if you measure power getting to the amp, you know the fuse is good.

Beyond that if you can get hold of a wiring diagram for that particular amp, you'll see the wire colors for the remaining connector pins, the audio in and out. Since you swapped the radio, assuming it was working or you can also get wire colors for it and measure audio out from it to the amp (multimeter AC 20V range when audio should be playing), you can measure audio input signal to amp, power as mentioned previously, and whether there's an audio output signal.

As for diagnosing an internal fault with the amp itself, I *might* be able to assist with that but not everyone would be comfortable with the repair which could include circuit tracing and probing with a multimeter, pulling chip #s to find datasheet(s), ordering from an electronics supplier, desoldering and soldering in new component(s)... Might find a used/pull amp for cheap enough that it's not worth the bother - don't know, never tried to find one.

Edit: HA! I didn't notice 3 years have gone by. You must be a fan of silence, and incredibly patient.
