  • Grounding questions.

    Ill be running 3 amps in my setup and the carputer. Now if I have 2 amps in the back and the pc and the other amp in the front, should it be okay since there will be 2 grounding points.

    BTW the amp in the front is 50 watts max 25 rms it is for the center channel. And about 675 watts rms in the rear.

    yes it will be fine, if you think about it you are grounding them to your cars metal from which is grounded to the battery. basically they are grounded at the same place. I would make sure they are nice solid unpainted grounds though

      Ive read other threads to make sure that your grounding points are the same spot. So four wires 1 grounding point or 2 and 2...

        you'll probably be ok with amps. I think the big problem is if you use an inverter and if you have two many ground points you get a bad ground loop.

            You should be fine. The only time you have to really worry about single point grounding is when you are gettting alternator whine. If it is an issue then I would say check your grounds and then maybe go to a single point for the ground if that doesn't fix it.
            Never let the truth get in the way of a good story
