I know there are some "Ground Sniffers" out there that can tell you the best ground location of your car, but alas I don't have one. I was wondering if someone had located the best or close to the best ground location in the trunk area of Tiburons? A pic would be great.

 

I have mine in the spare tire well.Works perfect.

 

After I put in my auto antenna, I found a really good ground with a bolt/nut near the stock antenna pole.

 

I used one of the bolts just under the backseat for my amp.....maybe you should look around there

 

seatbelt bolts, seat bolts, or just drill a hole in the floor, sand it to bare metal, and screw in your ground.

 

DITTO!

 

Yep the seatbelts bolts work perfect for the 4 gauge ground wire. First it's hidden under the seat and second it has a huge metal bolt with metal chassis to ground it so the amp will never loose contact!!!

 

I grounded my amp to the strut tower bolt. I grounded my battery to the center screw that the spare tire ties down with. I grounded some neons to the rear seat center bolt. Need more?
