weird..

So i get my new amp today back from cadence. Works great btw, sounds better than the new one, probably b/c the other one was off Ebay. Well anyways, i hook up the amp and it's all good but from one speaker, Channel 2 (passenger front speaker) has a very high pitched sound with a little static coming through it. It doesn't affect the sound or anything just when my volume is a 0 i hear a very very faint high pitched sound. Kind of like a mosquito ringtone thing.. And everytime I turn on my headunit i get failure on it, I know it isn't calling me names. But I wired it up really half assed this morning cause all the positive wires were wired to themselves and all the negatives were wired to eachother so that they werent touching. Think i should just disconnect all the stock speaker wires from the harness and just cover the ends with electrical tape so that the only output would be from out of the rca's? It's not like the old wires do anything anymore.

Question is why is there a faint mosquito sound coming out at 0 volume

So I unhooked all the speaker connections out of the hu. All I have now is power ground and rcas to the back. Why is only 1 speaker making this high pitched noise? It's not at loud but it's just slightly audible and bugs the shit out of me. It sounds like a mosquito ringer. It's around that frequency

try running speakers right off of the HU, see if the problem persists, if it stop when speakers are wired to the HU then its somewhere in the amp which is then when you should check all connections with the amp, power make sure ground is good, 100% bare metal, no wires crossing, rca cables on opposite side that whole thing

then if it still does it, then i dunno what to tell you //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

tommorow im going to swap rcas and see if it still does it.. I mean i could live with it, but i would rather it not do it. It doesn't affect sound quality
