Question for you guys.....I have a custom sound system in my car with 3 amps, 2 4 channel and 1 mono

first amp is 600, second amp is 900 and the third is 1000

if I change my UR pulley will that affect my system? Is there any way to change it and compensate for the loss?

my capacitor always reads 14.6 volts.

Thanks

You can use the stock sized pulley that is lightweight
but not the UnderDrive pulley- it will reduce the alt speed just enough that if you sit for 20 minutes with all that cranked up- it will drain the battery
The stock size lightweight pulley will still give performce gains from 8 pound weight loss and keep the stereo happy

It's the same size as the OEM pulley, just weighs less
