Ground noise is coming through my speakers, i just got a brand new Alpine CDA-9853.
I am running my remote turn on wire with my speaker and rca cables. Is it possible this is where the ground noise is coming. The only thing i can think of after this is new rca cables or a noise filter.

 

are you using to stock ground wire??? try puting a ring termial on the ground wire for the alpine and then drill a hole in braket in the dash and put a screw and attach the alpines ground wire to that screw....

most of the time it is a back ground

also do you have the power wire for your amp beside the rcas ??? if so put the power wire on the same side of the car as the battery and the RCAs on the other side...

take a voltmeter and put the red wire on the neg of the battery and the black wire on the ground wire of the amp and have the voltmeter on DC volts and if you read any difference in potential (voltage) the you have a bad ground on the amp

there for move the ground of the amp

i hope this helps

 

Also ... you can just run RCAs from the front to the back in the open to see if that fixes it. Instead of tearing your install apart. Either way, you are dealing with a ground loop so all that you have to do is Identify the problem. Try the steps that splescort told you to save some time and money. Be sure that your wire runs are correct as well throughout the car. You may have to move them.
