i've had dimming issues for awhile since i run a large amount of accessories, i really wanted a local alternator rebuilder to rip the extra alternator that i bought off of rsconvert. its $212 plus you get $30 back when you send him your core i went on and ordered a 140-ish amp alt from maniac a few days ago and installed in this afternoon...took all of 30 minutes maybe. i give it a thumbs up, the solid power source makes for much fuller and kind of even richer sounding bass. i still need to retweak the settings on the stereo but i am very happy so far, can't wait to really crank it sometime when i can without attracting unwanted attention and see what it can do.
i assume you have a chassis grounding kit of some sort as well? you'd be amazed how it helps all that stuff too
