Raising the rear seat brackets

[DeltaNu1142]

Because I'll never run a hard top, and I'm considering how I might use the space under the rear seat (possible subwoofer enclosure build), I'm wondering if/how anyone else has raised their rear seat by 1" or so. I'm thinking about cutting some unistrut the full length of the seat brackets, coating them, and using them as spacers... unistrut is 1-5/8", though, too. What I don't know is what the hardware is (M10-1.5? I'll need them longer than whatever they are now); and the Jeep's currently in storage.

@JMT, others, how did you do it? Now that I'm thinking about it... I could probably build some mounting brackets/tie-downs into the spacers somehow to secure whatever I end up putting in there. I checked into how Tuffy does it, but it looks like it's integrated into their drawer.

EDIT: ...and then there's the seat belts. The female ends are already pretty short.

I used aluminum bar. It's easy to drill. Just get some the thickness you need, same width or slightly wider than the LJ seat brackets, drill the holes, and get longer hardware (as you mention).

I used aluminum bar.

I didn't think about solid bar. I'll have to see if I can dig up some scrap. Prices are nuts... The McMaster-Carr price for 1x1 solid aluminum is about the same as 1x1 square steel pre-drilled tubing.

I always get my metal from local sources. You may be in the middle of nowhere, but the sources I visit have scrap piles with sorted materials for "ok" prices.

I meant to mention, it's a solid idea to get a speaker grille for the sub. That keeps the cone of the speaker away from the bottom of the seat if you design it up-firing. At first I didn't have one and two undesirable things happened. One, the cone of the speaker hit the bottom foam of the seat and made an odd noise sometimes. Two, if someone sat on the seat or something large was placed on the seat it muffled the sound. The grille solved both.

I'll have a look around. I'm from the middle of nowhere, but I'm currently living closer to the fringe of somewhere.
