the mount itself- said to use longer screws but didn't need to
Hopefully will get CB wired up tmrw and test it out, also added quick disconnect

Installed a Stereo system. Pioneer Head unit, Infinity 6 1/2 6022i all around, Rockford Fosgate 200 amp, 1 10" Kicker CVX Sub, Brutus 1600 D-class amp, and Power Acoustic 3 farad cap. There goes my hearing.
