4 ZV4 12 Trunk Ground Pounder Flatline 7k Build

Alright, I blew 2 subs at SBN 2014 and decided to come back bigger. The goal is to get as loud and low as possible. This will be a cone area ground pounding trunk setup with 4 ZV4 12's. I am building this completely out of the trunk if you can believe it. I will accomplish this by making it with two separate boxes. There should be 3.5 cubes per pair of 12's after all displacements which is not optimal but I have heard them sound really good in under 1.5 cubes per sub. The amp that will make these thangs bang will be a Flatline 7k. Let's see what happens!
