Next week I will be building a box for my explorer with two 18' HDC3's. Running a VLF 400.1 so these will get everything they can handle.
I don't have to much room to work with but it should do. 44.5 W 30 D 23 H. Was thinking of using aero ports and tuning to 39hz.
After searching the interwebz and seeing vids with these subs I wasn't very impressed by most setups. I guess that's what one gets with a pair of semi budget subs.
Anyway I would like some suggestions if you have experience running these in an SUV. From what I hear these need a lot of room and high tuning.
