I have a set of 10" rockford fosgate subs that were left over from my last car, but I only really plan on using one of them unless I can get a better amp any time soon. So I saw the rear side compartments on my wagon and the idea that I should fabricate an enclosure forfor the sub and amp (possibly both sides in a not so far future)

any advices? Reason for doing this is because I don't like having a gigantic box bouncing around in the rear, and I hate not having any room to put bags, groceries and such.
Has anyone done this? Btw I searched and found nothing

I don't know of anyone that has done this, but it certainly could be done. Fiberglass would probably be the enclosure material of choice. You're not going to have a lot of volume, so having a sub that can sound good in a small enclosure would be preferred.

You can buy a similar box from JL for the 05+ legacies.
