Do you have a way to mod a box?
I have a dual baffle dual chamber comp box cut for six 4" aero ports crx style with 12" cutouts for those baskets. (box fits width-wise in the back of an explorer)
I'll give it to you for FREE if you want to come pick it up in Vista off the 78.
Let me know, I'd have to meet you up there
Good luck on a box either way
Matt
