I was'nt sure if the rear seat should be left or not,I want to still use it to throw stuff back there,and still have the fold down capability.And as far as having rear passengers,dude get serious. But i'm gonna get some hefty speaker grilles and place over them. I might have to take some padding out of the seat backs to compensate,but I'm really happy with the results! And thanks to all for the thumbs up!
