Default quick question about pulleys..

I was looking to potentially change my Lightweight Crankshaft Pulley, but have a concern.

My friend was telling me because im running a moderate-strong sound system something about the pulleys not allowing the alternator to generate enough power?

Im running about, 700 watts rms and 1100 max watts.

p.s this is the pulley i was looking at http://www.rallitek.com/Lightweight-...-Pulley/p-4532 if anyone could give me a review or comment about that, as well as what kind of gain would i be looking at? Thank you so much.

The pulley that you linked to should cause no problems with your electrical components, as it is not an underdriven pulley (smaller diameter than stock).

If you have a lightweight flywheel, a lightweight crank pulley can cause difficulty shifting in stop and go situations (can vary for different drivers).

Yep, you want to stay away from under-driven ones if you're concerned about electrical draw. There are plenty of choices, so it shouldn't be hard to find one.

I know a few who run the linked pulley...no problems with electrical systems. A side note: Get a spare key for the cranknose from the dealer. It's 4 bucks i think, but it's one of thoes things thats nice to have on hand incase the stock key falls off and you cant find it. Other than that, the install takes 20 min tops.

Default shouldn't be a problem

Yup, shouldn't be a problem. The power level you are looking for is not that high and should work with standard parts as you linked.
