Has anyone got a 15: sub to fit in the rear of the xb. I wanted to make it fit in that area next to the spare tire. What is the biggest size box anyone has got to fit there?

 

well, it will not work. if you want it flat, the 15 will be hard pressed to fit in there, not to mention they need huge amounts of airspace. Here is a picture of a sub box I was building for my xB, but I changed direction.





That box is around 2.5 cubic feet and is still a little small I think.

 

here was my setup, memphis 15" mojo

about 3 cubic feet sealed box made of fiberglass and it was light well the box weighted like 10 lbs but the sub was like 40... lol so 50 lb box. easy to get to spare.

anywho here is the pic already hope this helped
