Any tips or help in repairing car audio amplifiers?

I have trouble uderstanding the power supply of one amp. I have disconnected the the supply from the audio amp section and then I connected an external supply to the audio amp and it worked just fine. Checks in the power supply include the MOSFETs, transformer, schottkey barrier rectifiers, filter capacitors and coils as well as the pulsewidth modulator IC.

The power supply just won't work. I have checked all solder joints. The protection feedback circuitry from the audio amp to the power supply is also fine.

Answers:

Does the ford 6000cd audio unit have an aux input?

Look up the data sheets for the components and use a multi-meter to see if the components are within tolerances.

car problem, need serious answers please?


This will invlove removing each component for individual testing. Be careful with the double sided circuit board and the static sensistive MOSFETs.
