    Just a thought, shoot me down if necessary...

    Did you read the above two posts??

    The accessory line is looking for 12volts. I also don't typically recommend grounding your amp at the battery unless you have a separate battery dedicated to the audio/carputer. Ground wires should be as short as possible and grounded directly to the frame of the car. Look for seatbelt bolts or something and scrub them with a wire brush. Also the thicker the better when it comes to grounding wire. Most ground wires I install are 2ft or less and are at least 8ga, if not 4. Not trying to flame knightofoldcode....

    I agree with this philosophy as well. Basically a groundloop is created when there is a shorter path to ground than the actual ground wire. This means that maybe it is easier to ground through your RCA wires into your carpter and to ground through the power supply and then you end up with noise. Keep the grounds short.

    Unless the power supply is grounded to the battery as well. If you ground everything to the battery and not the car frame, it'd be a ****load more wires, but wouldn't it also eliminate the possibility of a ground loop? Since "all roads lead to Rome"... but in this case the (-) terminal?

    Here is a good post on grounding for car audio:
    http://forum.sounddomain.com/forum/u...c;f=5;t=008251

    [i]"The goal here is to ground everything back to the chassis using ground points of equal (or to within .25 ohms) resistance."[/]

    Ground all your components to the same point, usually a nearby location on the car chasis. If the chasis isn't providing a good ground, then try grounding directly to the negative terminal on the battery.

    If you connect the ACC from a cig. lighter to your Amp Turn On, put a 500 to 1000 ohm resistor in the middle. This will ensure that only a small current will go to the Amp Turn On lead.

    I advise everyone here to go vote in the thread in Comments/Suggestions that is asking the admins to put in a Car Audio forum.

    All roads lead to Rome but electricity likes to take the path of least resistance.

    Ok. My cigarette lighter socket turns on when I turn the key to the acc position So that means I can use that 12v wire. With this resistor, http://www.radioshack.com/product.as...%5Fid=271-1116 (will that work?)

    Dude, you can't tell me you run a 10'+ ground wire on your amps to reach the battery. I've heard anything over 3' is a big no, no.
