Just curious before I get started... I'm planning on mounting my amp to 3/4 MDF in my trunk. The MDF covers the whole back of the backseat. Is this going to deaden the sound? significantly? Should I cut a hole in the center where the ski rack port is and leave it down? Just thinking for the best sound here...

IMO, it will help very little. The backseat isn't where you want sound deadening because the sound goes through the cabin. If anywhere, you want sound deadening on the rear deck, trunk lid and entire trunk bed, keeping the sound inside of the vehicle. I say remove your spare or leave it, build a false floor, and mount your amps to that leaving your backseat open just in case you put skis and/or need to fold the seat down for further storage.

 

Yeah, to clarify, I don't want it to deaden the sound traveling to the cabin, obviously. I was just worried that having the MDF there would hurt the sound quality. But yeah, putting the amp in the spare wheel well isn't really an option I'd want to pursue...

I guess I really don't have to many other options than to mount it to the back of the seat...

 

You can build a false wall also like in the mod for replacing the stock subwoofer. The modder built a mini wall to mount the amplifier he has. That will be my next project to build a full false wall with some custom fabrication.
