    best ground location?

    does anyone have a recommendation to where the best place would be to run the ground for my amp in the trunk of the e30? at the moment it's hooked up where the Radio ground is, but that doesn't seem to be working very well at all. i'd go look, but it's raining and it's dark. thanks in advance for the help

    There is nothing stopping you from running a ground wire to the battery. Other wise, any sheet metal will do.

      I believe its supposed to be a short a run as possible from the amp, so..........anywhere close.

          In an E30, the battery.

          Assuming your battery is in the trunk

          It's such a short run to the battery in the trunk hooking it up direct to the battery is best

            With only + signals coming from the HU, Is there any reason not to run the signal grounds (running to the amp) from the battery as well?

              i wondered if it was possible to just run the ground to the battery, but i didn't want to go ahead and try it and fry something, thanks, i can have my stereo back now.

                huh? No better ground than the negative terminal on the battery itself, especially for an amp.
