Thinking about adding aftermarket subwoofer system under the rear seat...

[BWL]

Final product. JL audio stealthbox with 2 10TW1. 3/4" seat lift, 1/4" load floor lift. Bolted down with grade 12.9 M12 1.75-75mm Allen bolts. Amps on back wall and got some automotive carpet underlay to underlap the back wall cover and under seat felt so no wires visible. All you see under there is the amp faces.

And seat lift was 3/4" thick 2" flat bar. Load floor lift was 1/4" thick 1" flat bar. All aluminum. One mistake I made which may effectother guys going back wall was with the seat lift the seat hit the amp and wouldn't go all the way back. I had to tip up 1 corner a quarter inch on the big amp to allow the seat room to go back in. For guys with bigger seat lifts this would be a bigger problem best not to have the amp behind a seat bracket if possible or just be aware you have to make it sit higher if you're lifting the seat and it's behind the bracket.
