    I have to pry out a lot fo moulding with a freaky psyco tool to run amp wiring in my 2003 Malibu, so I'd like to keep that to a minimum. So is it that important to run power and signal on opposite sides of the car? It'd be twice the work for me. It's only going to be bass frequencies if that matters.

    You have a Malibu? Since when! I thought that was a truck, with a canopy?

    I traded that in for the Malibu

    It's a lot more reliable, and I still have the rock truck and the K5

    I'd run them both on the same side.

    The main reason for running them on separate sides is to reduce engine noise. If you are using quality stuff you shouldnt hear any noise if they are right next to each other. Good Luck

    Its a hell of alot easier to just run them on the same side. I have done it in every system i've had and never heard engine noise or anything.

    Okydoke, thanks

    Just put the deck in the dash kit and it's NICCCCCCCCCCCEEEE

    It doesn't use the sleeve or the trim ring, which really cleans it up

    The two MTX4000 12" I had in my K5

    I could use the Pioneer 305SVC 12" I had in my truck but I don't think I'd like that as well

    Crap! You didnt order it from crutchfield though did you? If you guys need any audio stuff I can get you a much better deal than through those guys (No offense intended Resurrection_Joe). I cant always beat the price hacks on ebay but I can beat crutchfield 99% of the time.

    It is not so much noise as it is interference. Electrical current has a frequency band like a signal input does. I have had humming come through speakers because I laid the amp power wire next to the speaker wires. Engine noise went out about 25-30 years ago with the advent of electronic ignitions and shielded plug wires.

    i wouldnt say engine noise went out. i just installed my system, power and RCA's on opposite sides, everything done correctly and i've got a little motor noise. my buddies have had similar problems. i've got to go thru all my connections and amps and see where the problem is coming from.

    for subs i dont think i would bother routing on both sides. usually you only here the buzzing or motor sounds when running mids and highs thru an amp.

    you are right...as far as bass frequency and signals are concerned you are not gonna get engine noise or alternator whine...it normally only becomes an issue with a 4 channel or 2 channel that is running mids or highs...in which case they say run them at least 18 inches apart

    They should be run seperate at least 12 in apart. Power should be run down the same side as the battery if possible. And if you have to cross any of the factory wiring it should be done at 90 degrees. Engine noise is normally brought in by the ignition wires. A bad ground can also cause noise. You should run a ground cable from the engine block to the firewall (this also helps with other electrical problems).Sometimes the body does not have a strong ground due to rust at mounting points. Remeber, ground is your friend and should be 18in or less.
