wizart383 Posted March 21, 2014 Report Posted March 21, 2014 Make sure you didn't run your RCA wire near any electrical wire harness. If you ran your RCA wire on he passenger side their a harness between the front passenger seat and the b pillar that will cause the noise.
ducktordoom Posted March 21, 2014 Author Report Posted March 21, 2014 i have the rcas ran bye the drivers side with power wire but it is sperated
ToNasty Posted March 21, 2014 Report Posted March 21, 2014 i think that that running the rca on the opposite side is crap. ive done that plenty of times with no noise. the qaulity of rca makes a differance ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers
