fmedina Posted April 30, 2011 Report Share Posted April 30, 2011 (edited) So when I have my system on I hear this light white noise in the background. It's not very noticeable when there's music playing but you can hear if its a quiet part of the song or changing tracks. Is this the amp or hu? I have a pioneer hu and aq4x90 edit:ok so im still having this background noise! i got a new mbquart onx4.125 just cuz i wanted to try something new. new knu karma rca's. grounded the preamp outputs. signal and power wires are not touching. sooo... is it a faulty hu? a Pioneer DEH-P7200HD Edited July 12, 2011 by fmedina Quote Link to comment Share on other sites More sharing options...

fmedina Posted April 30, 2011 Author Report Share Posted April 30, 2011 Ya I just went outside and tried it. Only hu on and volume to 0 I can still hear the light static noise. When turned up to volume 1, still with no music, it gets louder. Quote Link to comment Share on other sites More sharing options...
MrSoHeavySPL Posted April 30, 2011 Report Share Posted April 30, 2011 try turning down the gain on the amp Quote 96 GRAND MARQUIS 2 Kole Kmx 15s 6.0 A.E. box tuned to 42Hz 1/0g power and ground Huge Duralast batt.

The dB was over 300 and the system burned down. Actually, 300dB is only about ¼ of this prototype sound level."

Supercharged DCs Posted April 30, 2011 Report Share Posted April 30, 2011 How are your rca's and remote wire run? Could be getting engine whine. Quote Bassless once again. Can't seem to keep a system for more than a few weeks Saving for a '06 Nissan 350z, look for build around June 2012. Link to comment Share on other sites More sharing options...
fmedina Posted April 30, 2011 Author Report Share Posted April 30, 2011 They are ran from opposite sides. Power and rca's are separate. Quote Link to comment Share on other sites More sharing options...
mr1mrwun Posted April 30, 2011 Report Share Posted April 30, 2011 IMO first you should check ALL you system related grounds. Making sure they're clean never hurts. Secondly, i would look into how you have your RCAs ran. You could be picking up interference from a power wire somewhere in your run. Third, look into grounding you RCA outputs on your pioneer hu. I ran into a problem like this when i had a pioneer hu. My research turned up that pioneer apparently has a grounding issue with RCA outputs on ALLOT of their hu's. Wound up having to ground all three sets of RCA outputs on mine. Not tryin to bash pioneer they make some good hu's they just happen to have an annoying problem with them.
