I will have to measure my back seat but I think its only 2-3" off the floor. I'd have to get another amp too. Lol. one that would fit under the seat too. It would be awesome if I could get a speaker with 400 watt RMS under the back seat!!!

 

there is a kit you can get to lift the rear seat 3-4" which would help too

 

How does that work?? Cuz the back rest of the back seat latches to the cab.

conanski said he used 5" c channel but i don't know about the latch...

 

Wow! Thanks for the link. It actually corrects the latch problem. I will really consider this. BIG TIME!

I have been looking for years, some way to "hide" my sub. I love my stuff like that where you can't see them, it gives a factory look with better performance.

 

no problem. i keep thinking about getting one or just making one

 

Thanks fellas, it's looking like my optios are quite limited if I don't fold the rear seat :/ . I also havent looked to see what speakers they are but IMO they sound just as good or better than my moms Bose system in her rainier.

 

Yes a rear seat lift can be done pretty easily and cheaply, two pieces of 5" c-channel under the front legs will raise it up enough to get a pair of 8" subs in there.. but only regular subs not those monster long stroke things like the Sundown. The rear of the seat will actually rest on the sub box and the latch is no longer functional so what I did was screw the seat-back to the rear wall just below the window. Other side effects are the seat no longer folds but that's no big deal IMO and the seat is actually much more comfortable to sit in so it's not a bad mod anyway.

P.S. I notice the LMI kit only gives 4" of lift, that would work too but it decreases the amount of room available for subs which is pretty tight to begin with, the floor under the seat isn't flat so the sub box ends up being a bit of an odd wedge shape and the drivers have to lay back on an angle, so fitting a 10" or 12" is probably not gonna happen.

 

Here is my setup and I'd be glad to go into detail if you like, as far as how it was built. They are 2 JL Audio 10w1v2's and can rattle all the glass in the truck.

 

Is that built into the bottom seat?? Did you just cut a hole and put the sub in? Can you feelit if u sit on that side of the seat?

 

I guess I should have added that this seat has not been raised or moved to it is still very usable. It can be a little hard to sit on for long hauls but not as bad as you might think. To do this you have to use shallow subs and make a slight riser for them.

 

You have to totally disassemble the seat and remove the springs inside. Then build a plywood speakerbox to fit and trim the foam till it fits. I left all the foam on top and stretched the seat back over it. I got my specs directly from JL Audios web site as to how much air space the subs needed to be in a sealed enclosure. Now that being said it is not 100% sealed sine the latch that holds the seat has to remain for people to be safe riding back there. As far as feel it is slightly harder but there is still some padding left (maybe an inch of foam).

 

What I was thinking was LMI 4" lift, and then a good shallow mount 12" sub, or possibly 2 12" shallow mount subs. And mount the sub recessed in the box, so its level with the box. Put the amp under the back seat on the passenger side, then build a box that stretches from the center of the truck to the drivers side.

 

This will give you an idea what you have to work with, shallow subs didn't exist when I did my truck so that opens up more options...

 

I was kinda thinking something like that, just I'll have to have a sharper angle for the 12's. If nothing else, I'll just build a square'ish box (with the speakers facing the bottom of the seat) and leave as much room from the bottom of the seat and speaker as possible.
