    I was planning on gettin asp underdrive pullies within the next month and i have been reading up about them alot and they give very good power for the money. What I have been hearing is that if you have a powerful stereo it might kill the battery very fast. I have a stereo that puts out around 950 watts rms and i am wondering what they would do to my car? :shrug:

    I don't have a big stereo like yourself, but at Idle my voltage meter sits a little less than half. I have a single amp and 12" sub with a factory deck. I would say just put the overdrive alt pulley on when you put the UD Pulley on and you should be fine.

    I dont think anyone makes an OD alt pulley for the 99+ v6, ASP just uses a crank pulley.

    You should be fine, I have a bigger system than you do, and the lights will only dim if I crank up the bass really high...

    Adding a nice-sized power capacitor to your stereo should help with the dimming lights.

    yeah but you got have some serious sized capacitor to make a differance, like a full charge on one is only enough to light a flashlight light for like a second

    I once had an Escort with five amps and a huge bastage of a 15" subwoofer. After I installed a Braxx 1,000,000 MFD cap, I had no problems what so ever.

    It constantly charges when the amperage drops down and then discharges when it sucks down a lot of power which is why caps work.
