I have a pretty demanding car audio setup (4600W+ RMS!), so I need a beefy alternator. I did have a 200A High Output Saturn alternator, but it appears to be dead. I currently have a stock alternator back in place to charge the main battery, but since I have no power steering or A/C, I want to install a second alternator in their place to handle charging just the other two Kinetic car audio batteries in the trunk. I already made a makeshift bracket to mount a second alternator which I will drive from the unused part of my UDP.

Before I just buy what I had before --> Saturn 91-97 SC/SL Series 1.9L 200A - $169.99 (http://www.motorcityreman.com/91scse1.html), I found this on ebay:

This looks to be simpler to wire up and slightly less expensive. It will come with a 4-grove pulley so that part should be okay (same as the saturn alt). Anyone see any reason why it wouldn't work? I just like that it is a 1-wire setup... less to go wrong.

I could also get this SE Voltage Regulator for Mitsubishi Eclipse (http://www.motorcityreman.com/sevoreformie.html) that basically converts the saturn alternator into a 1-wire setup, but I'm a little confused about how that is supposed to work and it's another $27.

Thoughts?
