I love the internet. Tons of BS information. Here is the bottom line. Now - if you have a HUGE, and I mean HUGE audio system then it's possible that it will cause a strain on the alternator WHEN the system is really pounding. HOWEVER, modern alternators have this thing called a voltage regulator built in that compensates for this. How do I know? B/c I ran Air Ride on a stock CB7 w/ not 1, but TWO 3/4 horse VIAIR compressors and when they kicked on, literally in less than a second the regualtor did what it was supposed to do and bumped up the amps. With that said, I will tell you this.... MAKE THE CHOICE between speed or audio. I am a musician, so I always have a system that imaged and staged correctly, but you can get that w/ replacing the door speakers and having an amped deck. Awesome sound, w/ none of the weight of heavy ass subs.

Now - those are the FACTS - here is some OPINION. Lightened pullies > underdrive pullies. Weigh your underdrive pully against the weight of your stock pulley - u might be in for a surprise.

If you have your heart set on audio, then call this guy - he is the END ALL to alternator issues and can beef up your stock unit. Good luck:
