A while back I did a completely new install including HU, components, coaxials, amp and sub back when I first got the Jeep. You can read here if interested: 2012 HU/Speaker/Amp Build Log
In that build I put a JL 8" W3 inside of the factory "sub tub" and used a MDF ring spacer to make it fit due to the longer/bigger magnet. I spent a good deal of time getting it to sound just right with all the speakers and the sub. The one thing that I could not get right was the rattling issue. I put CLD tiles inside and outside of the tub, put all sorts of padding behind it in between the tub and metal, etc. No matter what I do it still rattles in certain songs. Im thinking the sub is just too powerful for the plastic and it vibrates the whole assembly.
So I decided to yank out the sub tub and get the non-sub rear plastic panel that comes on Jeeps with no rear sub. It looks just like the drivers side. That will provide enough space to drop in a new box right in the same spot. Stopped at the dealer and the panel was $85 with tax. Not too bad.
I swung by my local sound place and they had a custom built box on the floor that caught my eye. It was from another project that someone had built and I guess did not want it. It was originally for a Smart Car. It had JL 8W1 in it and the odd shape and size of it is what intrigued me. Sorry no pics (I know, I know)...
The inner cubic ft was built around the space requirements of the 8W1 which is almost the same as the 8W3 requirements. However the odd angle of it was damn close to what I would have had built. I asked them to add a terminal plug (red/black buttons) so I could take it in and out as needed. It currently just had the wires poking through.
I grabbed the box as is with the 8W1 and ran outside to test it out. It sounded better than my 8W3 in the sub tub. And zero rattles. Can't wait to hear it with my 8W3 inside.
Everything should be in mid-week next week so I'll post up pics. In the meantime I ran some loom over my speaker wires on my amp to clean them up.
Here is the current rattle machine:
