Could someone tell me where is the best place to run a good ground in the trunk. I had my amps and a second battery grounded to the metal brakets that connect to the trunk hinges since there were already screws there. I had a problem where the ground in the trunk became weak and my system try to find a ground throught the radio and it fried my RCA jacks. Any help on a good ground will be appreciated.
When we use 0g we go to the frame rail and when we use anthing less then that we go to the seat bolt like tenor39 said.
Make sure you clean the area you are going to use for a ground of paint and ish also.
I drilled in the back left corner of my trunk and went down the the bumper bolts that go into the frame. You want to make the ground wire as short as possible. The seatbelt is a good place also, but it is hard to get a good connection there sometimes.
