Just about any part of the frame or body is good, as long as you scrape the paint off first. Do you need this ground in the engine bay? interior? Trunk? Undercarraige?

 

interior..sweet spot is to take off the armrest console...nice metal looking frame there...drill into it with screws, use the u-shaped connectors...beautiful grounds and ok im done lol

 

what bout nice ground in teh trunk?

 

im not sure, but when i hooked up my amp, i used the ground of going underneat the backseat and connecting it to some metal spot on the car and the nut there underneat hthe back setas. also a good place. no one see's or touches it.

 

heh for the trunk i just took off the cardboard and carpet outta the trunk and used a bolt that was on the left side of the trunk...works nice for my amp/sub.

 

Exactly, there are bolts holding the trunk together. Just take one of them out and put it back on around a connector and you got a ground. That's where my battery is grounded now.
