I was all set to start my 4" suspension lift install when the last part of an older planned project showed up. So I switched gears and decided to do my stereo upgrade before the lift. Probably a little easier at stock height anyway. Here's the sub box for 2 Kicker L7's (sealed) to go with the LMI 2.5" rear seat lift. Sitting right around 2.6 cuft internal space without the subs installed.

rear seat outer side trim panels trimmed; no interference with the outer seat nuts when the seat is in the folded down position! tin snips with relief cuts, a 3" sanding disc and some finish hand sanding with emery cloth = gtg

inner rear door/roadkill using patterns:


outer rear door:


speaker baffle or whatever its called:


I didn't do full coverage because I wanted to keep it manageable and somewhat simple....hopefully this makes a difference. Going to do a little work on the door panel and call it good.

What speakers are you going with in the doors?
And what are you powering the subs with?
I like the box. I have been getting stuff together to upgrade my system as well. Looking forward to see what you do.

I'll be using JBL speakers in the doors and Pioneer GM series amps to power the subs and speakers. Got the Kicker subs and JBL speakers for a great price last Xmas. Pioneer GM amps are nothing special but have been tested numerous times and shown to deliver advertised power. So in keeping with the budget theme that's what I went with.

Was $480 shipped with their 20% off special

Maybe I should have said "good bang for the buck" stereo install. My goal is to do a quality-ish install using what are probably considered middle of the row components/parts.

for the rear doors, instead of going with foam rings I'm going to try out these silicon rings. With the coaxial in place on the Scosche speaker adapter the outer edge sits just about flush to the factory foam ring......see pics below:

Excellent! When you install the LMI kit just remember it is a good kit, but not perfect, don't be afraid the move the C channels around for best fit. Also, on the newer trucks, if you fold the seat down, the outboard nut on both pass and driver sides will scrape your plastic (see pic)....I just trimmed the plastic pieces flush (easy to do when the seats are out)
