I forgot exact specs but from what I can remember its tuned to 32 HZ I believe and is between 1.7-1.8 cubes.
To colyn, I figured it was a coil over but when I looked at it, it had a spring with a shock in the middle and the word static written on the side. I didn't think it looked like a coil over at first until I kept staring at it. Oh well, I'll look at it that way since I don't have coil overs lol.
We put my box right behind back seat. Cut the cross brackets and shaved some seat mounting brackets down to fit box. Buttttttt, this box was built for the sundowns. The box can be actually a little less beady with these American bass subs. The subs aren't as long and magnet isn't as big
