Looking for s13 Alternator

hey guys, im looking for a better alternator for my 92 240sx, anyone here know of a good quality one? I am running a system that has 770 watts rms, so I need something that will be able to handle that. If anyone knows a good place to get one or has a good one for sale, let me know! Thanks!

1st off with 700+RMS run a cap.

2nd take your alternator to an alternator fab shop and get it rebuilt to at least 100+ amps.
