ground point in the car

Hey guys,
I am getting horrible feedback from my amp, becasue the ground point i have it on is not that great. Is there a specific area in the cabin for integra's that is a better ground point?
Thanks

Re: ground point in the car (D_TY3)

your best bet is using your DMM set to "impedance" to find the best spot.

connect the negative lead to the negative post on your battery, and poke around with the positive lead for your ground spot. anywhere that measures less than 1 Ohm is good.

make sure you sand the paint off the grounding point so you ahve good contact. another thing to check is your HU ground. do you ahve your signal wires running down the same side of the car as your power wire?
