Underdrive pulleys slow down your accesory drives... so that would mean that it would slow down your alternator, which powers your electronics, which would rob power from the sound system... right? Can someone say yes or no on this one for me?

Yeah I was wondering that... if you put on the underdriven alternator pulley wouldn't that rob power from your audio system? Sorry if thats a dumb question but I dont know.

Yes it does cause it's spinning slower. At idle with your a/c on and stereo loud, you might even stall.
