I went with a self contained thin powered 8" memphis subwoofer. It obviously won't hit super hard but it might work better than something in the trunk with the roof down. Another plus is that all the wiring and controls are on one side, making the install cleaner/easier.

15-SA108SP - Memphis 8" 150 watt rms 300 peak.

It allows the seat to move almost all the way back. Someone could still use the seat, a bit less comfortable but it works.

Ignore the floor that needs to be vacuumed



I used some threaded rivets to attach it. Of course, where I wanted to mount it was in the valleys not the raised sections...Didn't realize it was like that until after I drilled the pilot holes and removed the carpet. Some spacers fixed it though.



Brackets bolted to the bottom plate. It can be removed to make this easier.
