I am wondering where I would go to find Schematic's on Car amps. I would like to start repairing a few of them?
like a Rockford Fosgate Punch 401s, or a JL Audio 500/1.

You need to go right to the manufacturers..who may be helpful... or not. Smile

Most are pretty easy- switching power supply and two or more amps within the unit. Some parts are a PITA to get, and you'll most likely find that most are not worth repairing. I got lucky with some AS IS Pioneers on eBay a couple of years ago, I got four for just under $100, and three had a broken trace from the 'turnon' terminal to the amp. A design fault I guess, the traces were really thin.

Some amps will do a big smokeshow if designed poorly. Also, if you're dealing with SMT devices, you can ruin the unit if you don't have the proper tools to desolder them. I did that with a small Fosgate that I was practicing on. Good luck!
