On older motors some people like to pressure washer them down to clean them, also know as degreasing. I would have your current alternator rebuild. I'm on my 4th or 5th one from O Reillys to the point I don't even remember how many times I've changed it!
I did not pressure wash my engine haha. Would my current alternator have enough power to run an amp and everything? If it won't then I will buy a brand new high output alternator. If it will run it then I will have a local shop rebuild it.
