Got em, love em. You have sound system so I would consult some of the sound experts of the forum. They are good and I have enjoyed mine.

I paid i believe 100 and something for my power hypertech power pulleys and installed them myself and i didnt notice anything different. If i had the 130$ i would have spent it on something else now. Like an open element air intake or some other small mod that is necessary and worth the buck. IMO not worthwhile.

I have the Hypertech pulleys on my car. It does go to discharge a bit at idle. I have two amps a 250 Watt Hifonics and a 150 Watt Aura. My car is not a daily driver if you sit in traffic a lot you might just want to replace the bottom pulley. The pulleys do not actally add horsepower but free some up instead. It is not a major mod but it adds up when you do all the other little things.

Ive got em and think they are worthwhile - every little bit counts. Both pulleys are needed though to keep the alternator running fast enough at idle. I had a sub when i first got them and had no problems. Doug
