Reviews of Pioneer alternator

I have a Fox and this is standard on mine - charges great - I have a Pioneer 50W Mosfet DEH-4800 (I think that's the model number - one of those 4000's) Oversized 6 1/2\" in the back and 3 1/2\" in front - (all Pioneer) left the damn thing on overnight accidentally - music playing low and all - tried to turn it on - didn't even hesitate - cranked right over - I would highly recommend it being Scirocco compatible (later year I'm sure it'll work) idles great, charges great, great price too
