underdrive pulley
Which UDP is better the MPX or unorthodox.......also, cant find a ODP for the alternator anywhere....I can't underspin/underdrive my alternator b/c I have a really powerful speaker system....any suggestions about what I can do about the alternators pulley would be much appreciated.

RE: underdrive pulley
I have the AFX udp which is like the unorthodox Race udp.
I have a powerful sound system in my car too. With this pully, Gary said it's been tested to work with powerful sound systems. I drove with my AFX udp for about 2.5 years and then I replaced my alternator. I don't know if I had to replace the alternator because of the udp or if it was just about time to replace the alternator. I'm willing to bet it was the udp. I hope the udp doesn't kill the alternator b/c I'll end up wasting another Optima battery and another alternator. If I go through another alternator I'll know why.
