That is much cheaper than the other kit on the market. Good looking install. How did you ground it?

 

On the inside of the license plate holder, there is a similar metal bracket that is grounded to the frame. It was an L bracket commonly found in any hardware store. I bent it a little and screwed it in place to the frame.

 

I think it's chock full of garbage. The radio is junk at best, the mount is overpriced, and anytime you have to use proprietary crap like the Firesuk Firering, I stay as far away from it as possible. But, it's your money and your equipment, so buy what makes you happy.
