I have a pretty demanding sound system in mine 300 watt amp 10" J.L. alpine head unit pioneer door speakers but I,m gonna try it. I have an ASP UDP. I put UDP's on the 94 Mustang GT I had before the Mystique and it was a problem. Even with a 130amp alternator and big battery it would die in traffic at night A/C blasting Tunes blasting I got real used to watching the voltmeter and gunning the engine to get it to charge. Car was power everything and had electrical problems before I put the pulleys on.
