Box for 2 fi ssd 10s

[darevrin43 0]

I am planning on getting a box built localy for my two fi ssd 10s. I am going to do a ported box.

Can someone give me good dimensions that would be best for these subs?

[Kanaworm$ 292]

W x D x H = ? / 1,728 = Gross cubic feet - wood thickness, woofer displacement, port and any 45 degree corners and internal bracing.

How about giving us some info on what dimensions your working with inside your vehicle, amp etc, etc.

ok well i dono what ur saying but my subs will be facing up in my truck. So the height will be 12in, width 15, and length 22 and i wana tune to 32hz.

wood is 3/4 mdf. And fi website does not have the details on the ssd right now so i dono displacement

Amp is still undecided but it will prob be 1200 watts at 2 ohms when i can finally find one for for good price

If you take 15*12*22 = 3,960/1,728 = 2.292ft^3 gross. If you subtract wood thickness and woofer displacement (0.13ft^3*2) you get 1.422ft^3 not near enough room for a pair of 10"s.

oh ok well i got more room for like 2 more inches of height and 3 inches wider and prob can add a inch of length on to that

What type of vehicle? What voice coil option did you get, dual 4 ohm or dual 2 ohm?

its a 200 dodge dakota 4 door. Im removing my smaller back seat to have room for the box. I had them behind the seat with .6 cu ft sealed boxes and that just was not working for the ssds, i mean they got loud off 350 watts in those lil boxes but its time to wake them up.

Also they are 2 ohm dvc

With measurements given it will be possible to build a ported enclosure but you will have to go with a round port (Aero) vs the sloted design.

What is the max width you can go? Side window to side window?

[darevrin43 0]

the longest part of the box will be going forward, from back window to front window... i can actually add quite a few inches in that length really. I said 22 but i could even go up to 30. My width i put was 15 i can do 17. The height i dont wana go to high cuz i dont have an alarm and the windows are tented but people could still see the subs if they are up to high but i can do 14 at most on height

Any help?

I ran a few numbers, for an optimal sized ported box tuned to 32hz you'll eat up most all the room you have. I pulled up a 14"H x 17"W x 27" L, 2.4cuft net enclosure, 2.85cuft gross with driver, port and bracing displacement. Two 3" ports 12 1/4" long will tune it to 32hz and those dimension are building it with 3/4" MDF and a single baffle.

What about sealed with fi ssds, is there a lot of difference between that and ported, like sound difference and loudness

[altoncustomtech 773]

Simply by the difference in enclosures you'll notice a difference. I personally like the sound of ported enclosures over sealed. A properly designed and built ported enclosure can sound just as tight as a sealed (<--this is arguable by MANY people, I tend to agree with this statement myself) yet offer lower bass extension and is overall more efficient than a sealed enclosure above the tuning frequency.

So, a properly designed and built ported enclosure can get deeper and louder than a sealed, generally speaking. There are ALWAYS variables that can change that, ALWAYS. In general, however, that's the difference in the most basic terms.

Yea ur def right, i have only had sealed boxes that were tiny. I just hope i have the room for a ported. I just need a ported box design that will help me achieve good sound quality but also loud with the room i have in my truck

[altoncustomtech 773]

The enclosure design I gave you in post #11 is the OPTIMAL enclosure size for the 10" SSD's, it's the exact same size I was going to use in my Jimmy before I changed my mind and ordered Sundown SA-8's instead of Fi's 10" SSD's. They should sound just about their best in that alignment.

Oh ok sweet. Should i do subs up ports up?

[darevrin43 0]

I pretty much have to do subs up i guess, if i put them facing to either side they will face my seats or the side door. My box will be facing forward, long distance going from back to front.

[altoncustomtech 773]

Now that bit of info there you'll need from someone with experience with those trucks. I see a lot of guys doing sub up-port up but exactly what's best could be answered the best by some of the guys who's familiar with them.

do i have to post a new thread to find out who has a dodge dakota? Would it be a problem if the ports faced the seats and stuff though? or do they need room

[altoncustomtech 773]

You generally want at least 1 diameter of vent distance between the vent and any object. So using 3" ports you'll need about 3" between them and any seat or wall in the cab. I would actually recommend starting another thread, you'll get more attention to the inquiry that way.

alright sweet i posted up a new thread hopefully some dakota owners can give me some tips. I appreciate ur help
