baaudio Posted April 23, 2011 Report Share Posted April 23, 2011 Okay so I've tried a couple things already. Put a ground from batt to alt. Replaced a factory ground for radio to a solid spot on the body. Now the noise does go with rpms just an FYI. When I unplug rcas from 4 channel noise stops. I don't seem to have any noise from subs, primarily comes thru tweeters. I haven't tried playing a seperate source to the 4 chan. Any other ideas guys? The noise started when I got in my car to go home from work. Worked perfectly fine before. Only thing I did was dump water out of my taillight.

baaudio Posted April 23, 2011 Author Report Share Posted April 23, 2011 maybe one of your rcas has a short in it that could be. i did notice that some of the grounding ends on the rca's were loose.

bassinblazer Posted April 23, 2011 Report Share Posted April 23, 2011 It could also be high frequency noise that your subs isn't picking up because of the LPF on your amp. I would check that out also. If it is coming through your sub preamp too, then it is probably a ground loop somewhere in your wiring job. Also, bad spark plug wires can cause magnetic distortion as well, if they are shot, you may try replacing them as well. BassinBlazer JL[RF][Kenwood][AQ] I need a new amp! Sell me your amp!

baaudio Posted April 23, 2011 Author Report Share Posted April 23, 2011 Ya I have the Karma ss ones too. I figured it's the LPf that's stopping it. My sub rca's are kicker z series. But I'll try all that. I may try another hu too.
