OG BudBone Posted April 13, 2012 Report Share Posted April 13, 2012 I have 2 DC Level 4 M2 12s powered by a DC 3.5k. I know im losing a ton of output by having them in a sealed box. If anyone can design a ported enclosure for me, it would be greatly appreciated this would be my first enclosure build so im a big noob when it comes to enclosure designs the max dimensions are 42' wide 24' deep and 24' tall, this will be going in a 97 trans am back seat preferably tuned to about 33hz thanks in advance Quote 1997 Trans Am WS6 Pioneer DEH-P5200HD 2 DC Level 4 M2 12s 4 cubes tuned to about 34hz DC 3.5k 1/0 Welding Supply Ultra Flex Stock 140A alt Stinger Fuses & Fuse Holders XS Power D5100 XS Power XP3000 Link to comment Share on other sites More sharing options...
OG BudBone Posted April 13, 2012 Author Report Share Posted April 13, 2012 also a slot port in the middle would be nice and the subs firing upward Quote 1997 Trans Am WS6 Pioneer DEH-P5200HD 2 DC Level 4 M2 12s 4 cubes tuned to about 34hz DC 3.5k 1/0 Welding Supply Ultra Flex Stock 140A alt Stinger Fuses & Fuse Holders XS Power D5100 XS Power XP3000 Link to comment Share on other sites More sharing options...
Joe X Posted April 13, 2012 Report Share Posted April 13, 2012 You want port/subs up? or subs up/port to the front. Quote Link to comment Share on other sites More sharing options...
OG BudBone Posted April 13, 2012 Author Report Share Posted April 13, 2012 Subs up port forward or whichever you think will be louder, sorry, and also itd probably be safe to take off a couple inches on the height, I don't think the subs hitting the ceiling would be very good haha.

OG BudBone Posted April 13, 2012 Author Report Share Posted April 13, 2012 Or should I do subs and port forward? I'm torn haha Quote 1997 Trans Am WS6 Pioneer DEH-P5200HD 2 DC Level 4 M2 12s 4 cubes tuned to about 34hz DC 3.5k 1/0 Welding Supply Ultra Flex Stock 140A alt Stinger Fuses & Fuse Holders XS Power D5100 XS Power XP3000 Link to comment Share on other sites More sharing options...
AKT6190 Posted April 13, 2012 Report Share Posted April 13, 2012 (edited) In my experience i like the subs forward and the port forward i found that subs up hurts my ears more than hits me <--- when they are face up (my bad) i like to feel the bass subs forward does the trick!

AKT6190 Posted April 13, 2012 Report Share Posted April 13, 2012 oh and yes the subs hitting the roof would not be good lol Quote Link to comment Share on other sites More sharing options...
Joe X Posted April 13, 2012 Report Share Posted April 13, 2012 If you are not clear this is my suggestion BUT I could also provide a center port alternative: Port/ subs either up or forward firing - side port for better output, driver/passenger sides can be tested: Enclosure Specifications: Fb = 33.045 Hz Vb = 3.02 ft^3 External Height = 17 in External Width = 35 in External Depth = 17 in Port Width = 3 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 35 x 17 Left & Right Sides = 14 3/4 x 15 1/2 Top & Bottom = 35 x 14 3/4 L Port Internal Assembly Parts: Front to Back = 11 3/4 x 15 1/2 Extension = 13 x 15 1/2 Assembly guide: Also higher tuning usually gives you more output.

And yeah I know about the tuning, I just wanna dig down a little bit so I can some lows haha Quote 1997 Trans Am WS6 Pioneer DEH-P5200HD 2 DC Level 4 M2 12s 4 cubes tuned to about 34hz DC 3.5k 1/0 Welding Supply Ultra Flex Stock 140A alt Stinger Fuses & Fuse Holders XS Power D5100 XS Power XP3000 Link to comment Share on other sites More sharing options...
