bazooka sub grounding

[crankybear]

Anyone using the bazooka tube subs? Trying to install one and I can't for the life of me get a solid ground.. Any help at all would be appreciated!

Where are you installing it. Behind the seats. Any part of the body floor will do. Pull back the carpet a bit find a spot. Drill a small pilot hole ( of use self tappers). Make sure nothing is under spot where your drilling .Take the paint off with a bit of sandpaper. Crimp on a ring terminal and screw it down.
