Need a design for dual 15" ported box.


Recommended Posts

Just recently got my first car and have installed my old set of 15's in it, but I sold that and am ordering new stuff. I have two Power Acoustik 15" MOFO 152x's on the way along with a SoundStorm SSL 4000 watt monoblock amp. Using a 0 guage wiring kit. This is going in the trunk of a 2000 Nissan Altima SE, and my trunk dimensions are 32" wide, 17" high, and 25"(Give or take) deep . And I want to go ported and have a tuning of around 33hz. The subs would be firing towards the license plate and the port I'm thinking should be at the top back.

But what I need to figure out is the port dimensions and whatnot needed to get 33hz. Sorry I'm a little noobish with this, the help is appreciated.

Um, I dont' want to bring the bad news...but that's not really enough space for those subs, since they call for 3 cubs each...and just by looking at your dimensions...you're stuck at 6.43cubs without adding the displacement nor the port area. Unless you'll be overpowering them.

Well what do you suggest? Go sealed? Or would a slightly smaller-than-it-should-be ported box be better? The pair of subs has a 6000 watt total max, and 3400 watt total RMS. Given that my amp is 4000 and will be at 2-ohms they will be underpowered.

He could make it work. The port would have to be all external though

How do you suggest I do that? The port can't fit on the sides of the box, only along the top. And I can get a few more inches of height if need be.

Sorry for the quality of these pictures, I don't have a good camera. But these will suffice.

Trunk entrance height. Can't see the tape measure well but it's 17"

http://s1055.photobu...4-16_153023.jpg

Trunk height - 17"

http://s1055.photobu...4-16_152941.jpg

Trunk width - 38" but the trunk entrance will only let me put in 32"

http://s1055.photobu...4-16_152919.jpg

Entire Trunk

http://s1055.photobu...4-16_152803.jpg

So it can't be 38" wide unless I can like build a box in halves and slide each half in and then glue it together and whatnot once it's in and let it sit. If there's even a good way to do that, hahah!

Sealed. Can't do ported...unless it's a single sub....you just don't have the space needed.
