where to ground my amp

ive tried 3 sopts to ground my amp and its still not working anybody know where a good spot to ground my amp is?????????

i have a 96 and ive tries on the seatbelt bolt under the seat ive tried behind the headlight there is a bolt ive tried drilling a whole into the frame and i use a wire brush and sand paper to take off all paint and dirt but still notihn is working....... i heard something about u seat railshow about that one of those bolts

i just relocted my battery to my trunk, and what i did was drilled a hold in the floor of the trunk down, right ontop of where the exhuast is. when down there with the ground and took off the bolt holding the bumber on put the ground wire on that blothed the bolt on agian works fine. also i cleaned it up a little with a file.

I grounded mine to one of the bolts that hold the trunk carpet in.

You should try to take the amp out and connect the ground to the engine block. That will tell u if its a problem with ur amp. or not getting a good ground.

If the amp works when attatched directly to the battery you need to just add another ground for for the battery right to the firewall, or anywhere in the engine compartment. That's a pretty standard thing to do when adding an amp.

Alot of times i've seen it like this: say you've got 2 amps... ground wire from batt. post, g.w. from both amps come together, join them together and ground them the same place


amp 1---------|
batt-----------|-----------ground
amp 2---------|

thats what i did, i have 2 amps runnin and i drilled a hole in the bottom of the rear deck and grounded them both there and they work great, it could be your ground wire isnt heavy enough.... i have 2 8 gauge goin into a 4 gauge to ground.

I just pulled back the carpet in the trunk and attached it to my antenna, like where it bolts on, just gotta remove the paint so you get metal to metal. works fine for me.
