been looking at the angecy power pulley, from what i've seen on the forum, it seems to be the best bang for the buck. but was wondering, i haf 2 alpine amps and 2 nakamichi subs in the back, if i change to the agency power pulley, would i lose amps to run these accessories? how would i be able to check if it would be sufficient? thanks

 

Two things.
1. If you underdrive the Alternator, you will lose current.
2, From all that I have read from SEARCHING on the forum, you would make your car faster by taking the stereo out then installing pullies.

 

Add a volt meter to your ride. I upgraded my stereo system and added a prosport volt meter. It reads about 14.2 when the bass hits. I have (2) amps, (7) tweeters, (2) 8" subs, (2) 6x9's and (1) 10" sub....you should be fine.

 

Add a capacitor to your system and it should take care of the problem with an underdrive pulley
