[QUOTE="AltarCrystal, post: 3045961, member: 576763"] Alright, here's the basic shape of the box, and how it will look in the trunk so you can see what I was talking about... [IMG]http://img523.imageshack.us/img523/7407/boxshapeintrunkbz6.jpg[/IMG] The box is the 5-sided shape, not EXACTLY how it's shaped, but close enough. The yellow line is where the board will be cut to "hing" the carpet so I can still get my spare out. Now, for the tuning. I want to say before I say anymore, I have no clue if this will work at all or not, so I'm sorry if it's retarded [IMG]//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif[/IMG] For 2 ports, 4" in diamater, they have to be 34.7" long to tune the box to 30hz, or 30.15 to tune it to 32hz. Here's my idea. First, a drawing. [IMG]http://img341.imageshack.us/img341/2419/boxtuningii6.jpg[/IMG] To explaine that mess, the black circles are the holes on the outside of the box. If all goes well, they'll be flush with the box. If not, atleast smooth. The grey lines is the tubing running the the box, white dotted lines is tubing continuing to run BEHIND the sub, and the grey circle is the other end of the tubing in the box. Each tube will go twords the back of the box, either up or down, and then across. Finally, the third bend is probably just an elbow, just to get the opening away from the walls. They'll be on either side of the sub (as in, above and below). First thing I thought of was these tubes rattling, so I could braces them agaisnt the back wall no problem. Assuming these fit...is this possible? Or is this completely retarded? [/QUOTE]
