I did a commercial install of a Kenwood TK-6110, and put the radio on a pedestal mount in front of the center portion of the front seat in one of the new Dodge pickups.
I put the pedestal right up against the seat, and mounted the bracket so the radio hangs in front of it.
The radio is straight up and down. Looks good, everything is accessible, and it makes it real easy to route power and coax out of sight.
I recommend a extension speaker though, because the the radio's speaker is aimed towards the upholstery. That kinda muffles the sound quite a bit.
Good luck!
