[QUOTE="Boomin_tahoe, post: 8691507, member: 562180"] It does a little bit and here's why. Lets say I have a HU that has 5 volt RCA pre outs. I gotta amp that I wanna run. I set my gain correctly with a DMM and a 40 Hz tone, in this example just a sub amp. I don't have to turn the gain up as much vs. a 2 volt HU because thanks to the increased voltage pre outs.
