Sergeant_Skyrim Posted October 19, 2013 Report Share Posted October 19, 2013 Alright, so as I said in PM I'm going to post here with what I got real quick before I head to work. Didn't spend too much time on it so I might've overlooked a couple things, but here it is: ~6.5 net cubs on the bigger side of recommended since you're running a little less power to them, fits within your 20Hx60Wx20D dimensions and I even did 17D because I thought I saw that at one point in the thread. Tuned to ~34hz with ~102 square inches of port. I also changed the port width to only 5 inches after this just to see how much it'd change and it went to 32.44hz with 92.5 square inches of port area. Subs and port forward since I don't really know what sounds best in a truck like that, like I said you may have to find somebody else who has done boxes in a similar vehicle and figure out what sort of orientation sounds best.

gmsierra2000 Posted October 21, 2013 Author Report Share Posted October 21, 2013 also Joe X also chimed in on the box build and he recommend sub up port up, now my question is, I am going to be installing a sliding rag top on my truck full length roof top like this so my question is, if I have sub up port up with the rag top close/open will it effect the sound drastically?, should I point these speakers a different direction to get the most sound out of them.

CleanSierra Posted October 21, 2013 Report Share Posted October 21, 2013 You won't be able to pressurize a truck like that at all. You may as well not waste the time with a system. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
