hey guys, i am interested in getting a UR crank pulley and i also want to upgrade my sound system and i am wondering if that will be a problem.

how much % does the pulley underdrive? after i install the UR pulley will i have to be cautious about what sound upgrades i do so that it is not using too many watts?

thanks.

damn...just realized i posted this in the wrong section...sorry

Just get a lightened pulley with NO underdriving. It's all about rotating mass.

The crank pulley won't interfere with audio systems. If you are using a set of UR pulley's, the Alternator and A/C pulleys are the same size as OEM.
