Re: Car amplifier(Polk Audio PA660) question
I've opened a few of these now that I had marked as defective back when. Also got a few more that were in the batch and overlooked; two PA330s and another 880 and 660.
I've limited myself so far to testing outputs, drivers and smps MOSFETS with a meter. I ordered a quantity of each, as each of the four amps I've looked at so far has a problem with one or more of the above. Until I get some new parts, I'm going to swap some parts around and see how many I can get going that way; then replace the defectives when new parts arrive.
This is getting fun...may even get lucrative.
