I have under drive pullies, h20 pump alt and crank, and I have no charging issues. At idle, I get about 12 volts. When driving, it sits at around 15.5 to 16 volts. When I had my system, 1-15" sub, 2-6x9's, 2-5x7's, 2-3 1/2's and 3 amps, my voltage dipped a little when the bass hit, but went right back up. I also run the stock alt. However, I do encounter some minor cooling issues when sitting at idle for extended periods of time. But when I take off, the temp goes back down. I have nevre had it overheat on me, it just gets pretty hot. As far as the oil pan, I have no idea what to tell you.
