[QUOTE="Bun-Bun, post: 7709261, member: 584852"] I went to a local car installer and we came to this conclusion. The sub amp is radiating EMI into my RCA's (he tells me digital amps are noisy). I had the excess length of RCA coiled up under my amp board right underneath the sub amp. So I took the back seats out and everything out and rerouted the cable so that they are as far away from the sub amp as possible and coiled the excess cable behind the back seat. The noise isn't completely gone but it has lessened... I think. the true test will be with my GF in the car. These are the RCA's I currently have [URL="http://www.knukonceptz.com/productDetail.cfm?prodID=KRY2.6M"]Knukonceptz product detail for KRYSTAL KABLE 2 CHANNEL 6M TWISTED PAIR RCA CABLE[/URL] Local installer is pushing these [URL="http://www.gotwirez.com/p/96/rcasbk-17"]Got Wirez. RCASBK-17[/URL] He claims that they ran these next to some neon ballasts and had no noise come into the line. My regular installer closed up shop. I don't know if I really trust this guy. Probably just trying to sell me his product. And I really do not feel like pulling those RCA's out and running new ones... Thoughts? Anything else I can do? The 4 channel amps is close to the sub amp so the end of the RCA's is still 2" away from the sub amp. [/QUOTE]
