Yea I like the work on the fronts but not the placement, from an imaging standpoint I would think most of it would all get killed and sound like everything is from below you.
I would think the rears would be ok height wise since its closer to where the factory fronts are height wise. I would wanna do them in my truck but it would be ONLY for movie watching or something for rear passengers only. Basically a switch on the REM wire for the rear speaker amp so I could kill them at will.
