Where'd you see the 2" forward modification? All I'm seeing 2 1/2" lift on their site and FB. I'm trying to get two shallow JL 10's behind the seat and getting that extra 2" would be very helpful.

I have 2 10"s in sealed box under my back seat downfire boss 10 x2 800watt 400rms. No problems . no lift kit bout to upgrade the subs.
New Product! The LMI 1520 SA, Straight Ahead, is a unique product for the "aluminum Body" trucks in that it shifts the entire rear seat straight ahead 2 inches at the top of the seat and can be adjusted to shift the seat bottom from 2 inches up to 3.25 inches ahead.
I have a 2017 Lariat Screw and put int 2 JL Audio 10TW3 Shallow Subs with custom box behind the rear seats. I did not want to lose the floor space under the seats, and needed the seats to stay up and lock without hitting the subs. I had to go fiberglass custom box and trim some foam off the back of the seats, and the seat bars were still *JUST* touching the Subs when the seats were fully up, so I added a couple of protector bars on each side of the subs about 3/8 inch past the sub so the bar on the seat would rest against the sub protector bars. The seats still close and lock with a very small amount of extra push! See attached pics....
Protector Bar with rear seat fully locked and up, with modified seat foam cut out of back of seat, showing a good 3/8 space on speaker. Subwoofer with original headliner cut out (before I added the protection blocks on the sides of each subwoofer.
This is so clean and sexy, where is this guy?
I Would love to get the dimensions on this box.
I’m guessing he used fiberglass on the back by the floor and cab wall area.

Thanks! I had the sub box built at The Good Guys Stereo in Beaverton Oregon, and they used fiberglass to make a mold of the back (after I had removed the foam and the carpet). They made it big in order to get the 1.2cuft recommended empty space required by the subs. Then I soundproofed the back, see pic showing partly done, slapped in the subbox, and laid the carpet over the box and screwed it in where I could (seatbelt cover, release latch, etc). I have the amp under the passage seat. See pic. The whole system (which fyi is awesome) is completely hidden, and I have the space on the floor under the back seats, which I could not live without! Really glad I did it...

That is awesome!
it looks like they integrated the back wall carpet perfectly with it too..
Did you do subs only with the factory radio?
or did you add another amp for the speakers?
What a great execution, I think I’m going to inevitably do the same exact thing. Did you dynamat first and then have them glass the box in?
Did they do anything to let those rear cab vents breath?
do you have any pics of the protector bar you added or seat foam mod?
