baaudio Posted April 23, 2011 Report 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. Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k
Krazykid122 Posted April 23, 2011 Report Posted April 23, 2011 check your 4 channel ground man, thats all i can think of, your taillight could cause it, or it would mess with your other amps for your subs, maybe the 4 channel one came lose, i had the same thing happen on my old setup, when id rev the engine i could hear it trough my sub and it would get louder, i think i just re wired it all, its been a while, was in the old car. 02 Dodge Durango 1 Fi SP4 18" .v2 Sundown SCV3k @.5 Ohms XS D3100 up front Northstar SMS AGM 400 in the back All XS Power 0ga OFC 240a Apex h/o alternator Pioneer AVH-X2500BT HU Dual 0ga runs from the alt to battery Dual 0ga runs from battery to amp
