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 grounded mine (99 gt) on the lip that already had holes in it at the top of the trunk (closest to the back seats), but i had to use sandpaper to take off the black coating until it was bare metal then i just ran a bolt through it with a washer on both sides and used an o-ring terminal on the ground wire

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

If you've grounded it to the frame then it sounds like the issue isn't your ground. Maybe the power lead, the remote turn on, or the amp itself?
