I also added the KLA 8" speaker box in the rear passenger cubby. That really made a difference and elevated the entire system. Would highly recommend it.
The 993 frame suggestion is good to know, thanks.

I put an 11" JBL spare tire sub in the rear and it's way better than I thought it would be. The spare is too old to be used anyway.

I used some leftover toolbox liner with a multipurpose adhesive. Any 1/8th foam padding should work. Wouldn’t use anything thicker for the front speakers.
