hey whats up man, I will be building my first 4th order 2 chamber box for the first time. I have seen and helped many people build 4th orders. I will be using 2 re audio sx 10's. They will be in facing the the trunk. The 2nd chamber and port will be going through the backseat hand rest. The problem with my car trunk is that its wide enough but gets smaller closer to the backseat hand rest. I would say I have about 2.8 to 3 cubic feet to work with for the chamber with the port alone. The sealed chamber has tons of space. I would like to have the box tuned around 32-34 hz. Should I cut out the square port to be about 6 inches high, 5 inches wide and about 19 inches long? I did some calculations with those measements and the tuning came out to be around 33. I just need some expert advice and it seems that you know tons on 4th order boxes. I will appreciate your input. Thanks alot bro, josh
