2 Sundown SA 12 Enclosure

[bgowdy 5,000+ posts]

So i went ahead with the Sundown SA 12s after thinking about it all weekend and got a pretty good deal and a nice box with them. However due to its dimensions its not ideal for my Kia Sportage @ 4.4 net tuned to 32hz & 14.79"s port per cube, so i will use it as temp box until i get mine built then sale and make a few more bucks with this.

I have been doing some searching but im limited because im at work and everything is blocked and i guess the search engine on this forum is down, well it is for me anyway.

Trying to get a idea on the box(not design it self, im just going sub up port back). Im guessing about 4 cubes net after displacements should be good but im not sure on the amount of port per i would need and im going to tune around 32-35 hz.

Power wise: Soundstream Ta3k @ 1ohm rated @ 2500 rms (may increase power, may not. i assume not right now). I will say i had it playing pretty hard a few minutes ago on break and this is much easier on my electrical at 1 ohm lol. The lowest i seen at idle was 13.2v lol

So how much port do these tend to like?

So u have a 4.4cube box and u want to make a new one that's 4cubes? Seems like a waste to me. Seems like the box u have now should be fine.

sorry i forgot to include that its only 3 inches from my back hatch due to height and depth. It has no 45s or internal bracing what so ever. Its just a box lol. So i want to build a good sturdy box that will work in my hatch. I cant lay my seats down because i have alittle girl

I have heard a lot of people say 15 per cube for the best all around response.

Oh well your first post says " NICE BOX WITH THEM" so I thought it was a well built box.

My buddy had a box 4.25cubes tuned to like 34hz and it was ok.. redid the box to 6 cubes port 7"x10" tuned to 30hz and it's a 149db car from the trunk. He had a 3500watt amp on them. Space makes bass //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif
