man i need your advice, my speaker amp is a planet audio 300/4, i have system noise, i have rewired the car and tried everything, i have bypassed my eq, ran rca's over the seats, ohmed out the grounds at front and back, changed h/u grounds, tried a ground loop isolator, muting plugs, test speaker etc......my amp has rca pass thru's for passing signal to a nother amp or channels 3 and 4, i use it to pass signal to channels 3 and 4, now i noticed that when i changed rca's that the noise is significantly reduced, but still there, and if i un power my cva 1005 and unplug all rca's from the amp the noise still remains, i also used a test speaker at the amp, and still noise....

so after all this, you think maybe faulty amp, i asked you because i was wondering if you maybe knew of what else could cause a problem like this....besides maybe a faulty amp...

Run the power wire and the remote/RCAs as far away from eachother as possible, if you havent already done so.

done that rca's and power are always separated

Try some higher end insulated RCA's and also call Planet Audio and see what they say. I am using 2 of their amps in a boat install and they sound and work great. In this boat there is NO way to keep the RCA's away from the power wires since there are only a few wire channels built in and it sounds great. In other installs I have used JBL, Clarion, and Kicker amps, and I have to say none of them impressed me as much as the planet amps do sound wise, it may be me but they seem much clearer. The only thing i dislike about them is the way they have to be mounted since to put them in the boat you have to climb into tiny compartments and i kept slipping and ended up cutting my hand so I was unhappy with that.
