10-24-2013, 01:35 PM
So I've decided against the 4 OA 18's and am picking up a pair of hd 18's this weekend. I'm looking for daily only. I don't want to and will not build a wall. I have more than enough room to work with , the box will be subs up port back in a jeep cherokee with the rear seats removed. Any body with experience with these subs that could help me with airspace will be highly appreciated.
