    Well...I say it a lot: There's a guy I know who runs sine waves for competitions w/his 2.5kw setup and he uses a stock alternator just fine. That's the type of load that dynamic music will never see; especially at 500w. Maybe the alt. was on the way out?

    No...3 different vehicles and 3 different years. All same result. Ive ran anywhere from 500w up to 2800w, 5 farad caps, 1 farad caps. Could never cure the dimming at idle issue. Closest I got was adding an isolator and secondary battery. Where on other vehicles, running the same outfit, lights would not dim.

    03 GTP...Its got pulleys and stuff.
