FiBTLforlife Posted July 8, 2009 Report Share Posted July 8, 2009 (edited) ok guys, im trying to figure this out. never have had a problem with this in my other installs but this is the first high amp ive had in my truck. i have all my wires ran on the left side on the truck in a tunnel that runs from the front of truck to the rear. which includes the 1/0 wire, 3RCAs, remote wire, bass knob wire, and one speaker wire. now i checked the output on the amp, and on the front stage it puts out a wining noise from the rear stage as well. which means that the front RCA (memphis) would be bad, and the rear stage RCA (just got it today) would be bad. so i dont think its the RCA cables. i also have a metal bracket he runs under the amp. i have the amp sitting under my seat with the amp on top of this metal bracket. now i dont have it bare metal to metal. i put some carpet over the metal bracket then put the amp down. should i do something different than the carpet like maybe MDF? my grounds are good, power wire is good, no loose wires, no bare wires, no pos wire touching neg wire. so im kinda clueless right now guys, any suggestions or advice would be great thanks mike Edited July 8, 2009 by FiBTLforlife Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...

Shibby Posted July 8, 2009 Report Share Posted July 8, 2009 I put a screw through one of my speaker wires once. I would just fallow every wire to make sure nothing happened. Did you recently do anything to car, ei. remove panels, something could have happened there. Quote Link to comment Share on other sites More sharing options...

FiBTLforlife Posted July 8, 2009 Author Report Share Posted July 8, 2009 ok guys, i ran the RCA's opposite of the power wires, re grounded the amp and even sanded down the metal. checked for shorts in wires, no shorts. no speaker wire touching metal. i even took the RCA that runs to my AQ amp and disconnected it from the HU and ran it as the front stage RCA (stinger). it still does it. so now im like clueless. amp is bran new never been hooked up bf.

BJD3 Posted July 8, 2009 Report Share Posted July 8, 2009 I have an idea, and I think it would work, but I'm not 100% sure. Heck, I don't even know if it is safe. Granted, this is just trying to find where the problem is, not necessarily fixing the problem. Turn the system on, then go to the amplifiers and one by one, pull RCAs. If the noise goes away, you know it is in the RCAs forward. If it remains, it's in the amplifiers backward. From there, you can go about swapping items to see if that changes anything.
