[QUOTE="VWBobby, post: 7303976, member: 624844"] Obviously a lot of people in this thread haven't played around with pre-amps and power amp gain settings.... Anytime you bump up your gain, you are amplifying more noise. Garbage in, garbage out. Lets say you have a 15 foot run of RCA's from the front to the back and need to crank up your amp 3/4 of the way to match your front speakers. Usually you will hear a slight hiss. The noise floor is higher and sometimes the sound is compressed or squashed sounding. Anyone who's played electric guitar or bass knows all about the noise associated with high gains, cheap cables (microphonics) and change in tone. Same subtle hints happen in car audio if you listen for it. In short, there's a reason high quality HU's have 4-8V pre-outs verses the mainstream 1.5-2.5V outputs. [/QUOTE]
