[QUOTE="audiolife, post: 162853, member: 541383"] higher voltage allows you to have a higher noise floor. if you have a very high signal to noise ratio with anything over 2v (in system) you have the whole thing pretty much whooped (meaning i doubt you could tell much of any diff with ear). higher voltage does not "reject" noise. the distortion you are talking about is due to not matching impedences via output to input just adding voltage will make it worse (aka amplify a clipped signal) what u need to do is level match everything (im gettin ready to do this to a car with 12 amps lol ..fun fun [IMG]//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif[/IMG] ) and the voltage changes in the signal path about the same as it does from the outputs of an amp important part here is to not clip in our clip out. to do this with a single amp system a voltmeter and an osiloscope is needed. when doing a system i add an rta for a sound leveling effect to find a true linear setting between sub and reg speaker amps. there are many reasons i do this (some say its unecessary) but it helps you learn what the car/system will do prior to doing anything drastic. there are also alot of decks claiming high voltage out (4v and higher) look at them via an osiloscope i think youd be suprised they dont do it cleanly enough to use to full potential. i could tell you about the worst two weeks of my audio life here but its a sad story and is through this expereince i put it like this. if i knew then what i know now id be a happier camper lol prolly a lil more famous too lol and no i am/was not tryin to insult you if we were having a convo and i said this you'd prolly been smilin at the way i said it [/QUOTE]
