Knowing you're supposed to avoid running signal cables alongside other sources of voltage to avoid picking up interference (even with the best shielded cables), I've always gone out of my way to avoid running power & signal cables/wires together, and also to avoid running RCA cables and speaker wires alongside factory wiring.
However, since I realize Cadillac has so many billions of wires and hundreds of wire looms and harnesses and a sensor for just about everything except telling you where to find cute single gals, I'm worried now. After seeing how many boxes and computers and motors and other wiring is in the trunk, I'm worried about how/where to run my single 6-channel Monster Cable RCA cable back to my amps in the trunk, plus how/where to run my front speaker wires back up from the amp to the front doors without running them along factory wiring! (I'm not concerned about the rear deck speakers or the subs because the wires will remain in the trunk.)
I haven't got started on the job just yet, but I'm already worrying. Has anyone else ever had any issues with interference from factory wiring when running RCA cables and speaker wires under the door kick panels? If I have to, I'll run my wires and cables along the TOP of the car just to avoid all the factory wiring.
I appreciate any advice or opinions. I might be worrying for nothing, but one can never been too careful when it comes to sound quality!
