buzzing from speakers/amp

[rco8786 10+ year member]

ok im running the small amp in my sig for the coax's. and the problem is there is a constant buzzing from each speaker. it is completely unrelated to alt/ignition as it is the same volume at all times. i thought it was ground so i redid that to no avail, then i thought i needed some rca mute plugs, but the other rca jacks are for rca out(to run rca's into another amp).. would this still be a muting problem? it sounds cheap but i don't wanna destroy a 5 dollar pair of rcas just to test something.

are your power wires and rca's down the same side of the car?

Unplug the RCA's from your amp. A muting plug is better than an open, but at least you should be able to tell if the noise is comming through the RCA's or if it's the amp itself. If the noise goes away then hook up another source, like a portable CD player. If there's no noise, then the amp's OK and you need to track down whazzup.

nswartley: no

maylar: good idea i didn't think about taking the RCAs out completely.

finding noise is a talent that very few master. Go ask a shop that you trust.
