FR uses a reverse hinge to secure the cabinet door where the subwoofer is located. I removed this hinge (Still need to fill the screw holes). I then located a similar door handle (match door above) and installed. I installed a door latch. There is a square hole on the left inside. I had some peg board, so cut a piece to fill the hole, after tucking in the wiring. I then needed to protect the 8 inch subwoofer. I looked for a speaker cover but couldnt locate one, so I got a under the shelf wire shelf at walmart, I cut it up and made a few bends to use small screws for attachment to the speaker front.
The mod gave a space to tuck a few thing in. Will still not want to block the front of the speaker. Also, the L bracket installed at factory was not screwed to floor, however the screw was laying next to the bracket
The sub is top heavy so still seemed to want to tip fwd, so I secured the top of the sub to remedy.
Happy Camping to one and all.
