Okay, so I have very little room to work with, and needed help on how to port a wedge box. I have 2 designs I can use for the port, both are using the same box. Width: 15 inches. Height 1 (front): 12.5 Inches Height 2 (back) 7 inches Depth: 18 inches total volume (using 3/4 inch think wood) = 1.06348 cubic feet. So one idea is to place the port under the sub which is the eaisiest. 13.5 inches long, half an inch tall, 14.5 inches of port space (32hz tuned) ^ I need to know if theres anything wrong with this idea? The 2nd idea, which is more complicated, is placing the port on the side of the box. I have no idea how to calculate such a slant. Would the 1st option be …

What would be the best way to wire into the box. Best as in the most secure, and most current flow. A friend of mine just drilled holes and fed the wire through, then just siliconed around to seal it up. I have also heard of people driving bolts through and wiring to them. If this will work, what type/metal bolt would be best. My last setup used actual terminals that I got from Sound Advice. I siliconed the back of them in, but not sure if they were secure enough. All advice is appreciated.

Hey guys just looking for a little input here I have been doing some measuring and test fitting cardboard templates to see what I can fit behind my seats without having to loss a lot of leg room. I came up with this set up. Dimensions 13”H x 20”W x 5”depth1 x 8.5”depth2, with 3/4 MDF it gives me .646 ft3. The Sundown SA-10 specs say it will do fine in a sealed enclose at .5 ft3 so after displacement I should be right on track with .546 ft3. My only real concern here is the mounting depth at 6” I should be in the clear right?

If I can get enough interest I will be doing an IASCA judge training April 11th and 12th in Santa Rosa. I need to get judges up there before I can have a good amount of shows. If any of you are interested in attending a judge training in Santa Rosa please email me at [email protected]. The training is $100 for both days. It includes a full year of membership in IASCA (which is normally $60). Even if you just want to compete the judge training is a great way to get a full understanding of the IASCA rules. When you consider that you get the membership it boils down to $40 for 2 days of SQ instruction. Schedule is: April 11th 9am-5pm -IASCA philosophy -IASCA classes and …

I need some of you guys to make sure my calculations are good and that this box will work out. This is the first box I have designed to be as critical as needed. I am wanting to try a subs back and port into the cabin approach. This should work out to 6.75 Cu Ft after port displacement and after the 15 " BL's it should have 6.39 Cu Ft at about 32 hz. I am wanting to try to make it bigger and get maybe close to 4 cubes per sub. I have about 7 or 8 more inches to work with to make it a little bigger. But I figured I would make sure I am doing this correct before I go and design another one.

I have 2 ReAudio SE 12's. I need a box design ASAP. It's going to sit in the back seats of my 2005 Chevy 4 door 2500HD. So the box can just be square, port center or one side. I want it to hit low ( listen to rap and rock ) but at the same time be ok in comps if I want to go ( for fun but still like to do good. ). The reason I just want it a simple design is so I can remove the box when needed not much room behind the seats so that was not an option. I plan to make this out of 3/4 MDF as well so may need to brace it. I will need a design with all measurements of course. I am just going to have lowes cut the peaces for me. A 3D design would be great so I can see how it all…
