ok guys first off how many amps is my stock alternator producing on my 01 gt? now i have a jvc deck with a 500 watt rms alpine amp wired at 2 ohms to my infinity perfect sub it is putting too much drain on my electrical system, i do have a cap and yes i know its pointless i just like it for looks but i know thats not supposed to fix the problem all it does is store the voltage i already have produced by alt. but i think the main reason my system is having problems getting enough power is b/c i have the steeda underdrive pullies and i know they cut down on free electrical power. i was lookin on american muscle and see they now have a 130 amp alternator 70 amps at idol, i was wondering if this was a big enough upgraded alternator to fix my problem, i also plan on upgrading my big 3 this summer as well

 

Your stock one is between 100 and 120 (can't remember the exact number). If I were you, I'd get the 200 amp one and call it a day.

 

ah yeah thanks man, know any good sites and prices for a 200 amp that will bolt right up to my stang?

 

Summit has 135-200 amp alts from $200-400.
