Opps, yea I drilled holes and the unit has multiple mount holes and I put 4 allen head metric screws in to the holes in the unit through the bracket. You just have to be careful as they can only extend 6mm into the unit.

 

Got it ...my girl can get a good deal on the Kenwoods right now and I'm looking into a double din now. Or I might just stick with another flip out. How do you like your Kenwood?

 

I love it, it is actually better than the specs. It has a 5 band eq. and its got an adjustable DSP plus it has a built in 24/18/12/6 db crossover thats full frequency programmable.
Besides the flush factory looks rock.

The Doulbe din install was easier than I expected!
