i'm looking for a ground for my new stereo. any help? is it that thing behind the stereo with all those black wires going to it? it's a 93 tg if that helps any. please help....grimmy

if you're running a new amp, run a separate ground straight back to the battery, and don't use cheap wire

i am running an amp and it states not to use over 30" of wire for ground because of engine noise. can i run one to the battery without worry? what size wire? thanks grimmy

you can run new wire back to the battery just go up in the size. If you plan to add anything else, I would recomend running at least a 4 gauge wire to the battery set up a ground dstribution block with 4 8 gauge outputs on it and dedicate to the stereo items and. Also do the same for the constant power. Usually 4 gauge will get you by with some decent draw on the amps without getting warm to the touch if you are gonna pull a large amount of amp power (4000&up) then run a Aut gauge(sp). Also dont skimp on the as well as connectors to have it all last.

Length matters- the more current you'll draw...the bigger gauge wire you need:



Ignore the "not to use over 30" of wire for ground because of engine noise" statement. That applies in cars, where the metal chasis is a way better conductor than any cable you could install.

In a boat, you need to run your own grounds to the battery.
