[QUOTE="DDSC, post: 4704473, member: 577647"] Hey all I got a DD 9518 and I need to put a box in my car, Im thinking about taking one of the back seats out for the sub to sit and porting through the armrest. The sub will be slightly recessed so I can put the seat back in and the aeroports will come slighlty through where the hole in the armrest section is. I dont know for sure but im thinking im going to get around 4-5.5 cubes out of the trunk. Question is how would the sub sound in a box of that space range tuned to 30hz off of 1500 watts at first and 3000 later, would it be lacking on the high end and overpowering the lows or what and how many/what size ports would it take to get that tuning, if possible I would like to make plugable ports to change the tuning on the fly (has anyone heard/done this, what were results) which I think would mean more would be better as you would get more tuning options. Im aiming for 4 of them and being able to jump from 30 to 45 hz tuning in 5hz increments. here are some pics of what the box would look like roughly [IMG]http://a410.ac-images.myspacecdn.com/images01/120/l_51dbfb7acd009fd3ae2e3662cc5c2909.jpg[/IMG] [IMG]http://a977.ac-images.myspacecdn.com/images01/72/l_f4d166822f8f66a70a37db08fce525a8.jpg[/IMG] [IMG]http://a75.ac-images.myspacecdn.com/images01/113/l_f5cf2eb208175fc4e2b8f8c8005fc3ea.jpg[/IMG] [/QUOTE]
