[QUOTE="T3mpest, post: 6616552, member: 560148"] First thing to do is figure out where the astro peaks at when you reinforce the boundary that will be your wall. Put in a sheet of mdf to simulate your new back wall boundary, put a sealed sub in the vehicle and compare each frequency to what winisd says you should get. The highest difference is going to be close to your peak frequency once you get the actual subs in. Assuming you can keep everything from flexing and messing with it, but obviously you'll have to test the BTL's eventually anyway and possibly retune slightly. That method will get you very close though. Anyway I vote for a tapped horn enclosure if you want to be VERY cutting edge lol. [/QUOTE]
