May I ask why.Want to trade my sp4 for two hdc4 12's or two hdd12's I will add cash.
Wow, I had similar issues trying to get my enclosure in also, it was a pain in the a.. What amp you have for the sp4?I have a four door car and for me to fit the box in my trunk I had to build it in the trunk. I had to remove my rear deck speakers to fit it. Trying to down size without loosing the power handling.
put that sub facing up towards the trunk lid thenMy issue is height I can go wide and have a lot of depth
