So since May I have been running an IB setup and like it pretty good(not having a big box in my trunk more than anything) but just think about different stuff I could do. I was looking back at my build pics and this idea popped in my head. Probably dumb but how would it work if I made a wall across my trunk about where that white paint starts where that wire is coming up through the board. Sealed everything off really good and dropped in ports from my rear deck. Might not even be enough air space for the subs idk I have not measured
