Engine Light
 

Recently i put 2 12" Alpine Type S subs and a Alpine 600 watt amp in my 01 gti. I dont think that im getting enough amps. so my question is where can i find an alternator that will handle the load, because i put a power cap on and it hasnt helped much. has anyone had to put on a aftermarket custom alt. ?

No, you don't need one unless your alternator sux and is dying. I've hooked up hundreds of systems, and you have a capacitor, which stores battery power so when the bass hits your lights and everything don't dim....it should be fine unless you hooked something up wrong. I have 2 12" Alpine type R's, with a rockford 2400 amp and I don't use a cap and I run fine. Somethings hooked up wrong.

everythings hooked up correctly but apparently it was my mass air flow meter

huh? did you think that you were losing power from the amp but really you werent? cause otherwise i dont get how it could have anything to do with the MAF.
like bagel said, alt should be fine, i ran two fifteens with two 1500 fosgates in my old grand cherokee with no cap and never had a problem.

i thought it was from the amp but it was becuz i had put a reg. k&n panel filter on there and i believe that the oil from the filter got to the MAF, plus the guy at the VW d-ship said they had probs in the gti with those
