Looks like a fun set up. Must say that the bass controller could be installed in a better spot. If it's anything like the one i had in my 1st gen, they give you plenty of cable to work with. I had mine mounted under the dash where it was out of the way but still very easy to get to. Inside the center console would be cool too.
The rest of it looks great though.
I've had my RF 10s for almost 4 years now and they are still sounding strong! And I think your bass control is just fine where it is......if you don't smoke what do you need an ashtray for anyways? I just use mine to store change.
