View Full Version : Sub Box Help for 2 13.5 JL audio w7s

So I have a crew cab 2008 sierra. And I want to take out one of the rear seats. 2 of the seats are attached to each other, however one is not and could be taken out. Would removing one seat allow me to make a large enough ported enclosure for the 2 13.5s? It can be as tall as the headliner.
