I am looking at buying and installing this JL sub box behind the rear seats in my RL.

My concern is that it is NOT a tapered box but a squared off one. Has anyone installed one yet? If not, for those who have put in aftermarket subs is the seat going to hit it and make it impossible to install?

Any advice is appreciated.

Here is a lengthy thread on replacing the stock sub. It has dimensions listed. It seems the JL you propose may be too big, especially top depth. You may be able to add a small amp to the stock sub to give it a boost. Do a search, it has been done before.

Sorry, it's too big. At 11 inches high you only have about 3.5 inches of clearance between the seat and the brace on the back wall. The seat wont slide down and properly bolt into place with that behind it. I quickly made an ugly box as an experiment. Its not to hard if you take the time and look at things behind the seat first. Course I did remove the factory XM bracket AND relocate the rear window motor by flipping it up out of the way. But that was to gain horizontal space, the same problems with depth clearance apply to your JL box.

Nice project. How does it sound? What amp did you use?

Sounds decent. I was almost satisfied with a different sub in the stock plastic box and a small amp running it. But it wouldn't play quite low or loud enough to keep up with deck power. This new box is almost half a cubic foot ported and plays down to 30hz range shockingly well for an 8. I threw one of my old Soundstream Reference 160s behind the seat for now but am already searching for a 10 that will fit. Also a plus about the longer box is the speaker is no longer right against the seat brace bar so I don't have to worry about that. There is at least an inch between the front of the sub and back of the seat.
