Here is the problem, most of the time i dont have time to answer all the questions about the box, as they are not all easy to answer. I usually pop in check the DC forum and leave and get back to work.
I will fill you in on the box here quickly. Currently 6th order, rebuilding to 4th order to try it out. Truck is a all wood build, to keep the weight down and keep Jimbo driving to the shows, including 32 hour each way to finals. The main thing that makes Jimbo wang is the testing time. It has been rebuilt many times over. The volumes are to small, dont know exact but thats not important, they are as big as i can make them in a tiny vehicle like Jimbo. If this was a astro it would be much louder as i could have proper ratios to make it efficient. But approx 4 subs share 7 cubes. But with enough testing you can make anything work, this is the trick, test hard and trust in your equipment to hold up this is why i use DC subs and Stetsom amps. On that note 14,000 watts of power from 4 Stetsom 4k2d amps, and 8 DC lv4xl subs 8 Powermaster D3100 batts. On top of that it helps to be ran over by a semi atleast once before you try to build a truck like this. Makes it more challenging. I will dig deep and try to improve on my score on sept 13th for the next 2x dB Drag event.
