As title says wanting to raise the back seat up a few inches higher to add in a sub woofer box. Anyone done this?

 

Put some spacers between the seat mounts and the floor. You will need longer bolts.

 

This seat is the folding. It doesn't mount to the floor.

 

It may fold, but some part of it mounts to the floor or it would move around while driving.

 

True. I'll look into it more this weekend. Looks like mounts are behind the side panels. And a arm comes out and that's what they mount to. I've got two sundown sa8's that are asking to go in. And i need to remove the side panels to install new rear speakers. Gonna make some 6x9's fit back there
