Is that the biggest you can build your box. If you want your sub to be in a 4cuft box , you will have to make it like 5cuft because your slotport is going to take up about 1cuft or so of air space. Google slotported box ( images ) and look at some pics to get an idea of what you need to be doing. Then go to 12volt.com and go to box/port calculator. Play with all the #s you can think of. You can use the sqaure box calculator to figure out how much air space the slotport is going to take up and add it to the box you have. Just remember to put the wood thickness in. It calculats outside measurements....

Well what i mean is I see alot of big boxes usually they are 5+ cuft and instead of using a slotport it looks like a big hole. Picture a box front and above the subs is a hole that looks like 28" wide by 6" tall and goes into the box like 5". Basiclly I guess just a huge wide short port. I dont know if its for burps or will work for every day use? I just am interested in trying something different.
I got it they can do a port like that cause the internal volume is so large. Thanks to 12volt I figured it out. I just played around on it for awhile. I just thought a larger port width would sound cleaner and get louder....

Not really what I wanted to hear but it is what it is. Sounds like a project to do If I got nothing else going on. About the 2" wide port, I see alot of pics of boxes with whitch looks to be at least 4-5" wide port but not that long. Are they doing it wrong or could it be just the pics and no real scale to compare with. I know its wider then 2" though. I got a little port noise with mine when the trunk is open. Whats the deal with these I see that are like 28" wide 6" tall and only 4" long? Do they work good. I got to say I LOVE MY SSD!! Ran it at 1 ohm off that pma1200da and it was crazy loud but didnt smell to good, I blow my 60amp fuse when my amp hit 11.2 volts it had to be real dirty power but the sub took it like a CHAMP.

Can anyone give me an opinion on what a bigger box will do before I have to build one just to find out.? I also am having a problem with the port design. For a 2.3cuft box tuned to 33htz I did a port 3.5" wide by 14.5" high by 44.4" long BUT I dont have 44" to do that so can I make 2 ports at 22" long? Any help with this would be great. Thanks, Bubba

Hello I have a ssd12+bp running off a Alphasonic 1200da at 4ohms. Rms is 1200 at 4 ohms BUT my electrical system is stock so with around 50-70 amps at 12.5-14 volt I believe Im only getting 550-700 watts to my sub. The 12 is in a slotported box with 1.6cuft tuned to 34 htz. I built the box for 2-12 so they each have their own seperate enclosure, but I can not see another SSD 12 in the near future cuase times are tuff. My question is this- If I build another box for my 1-12 at say 2.3cuft with a slotport tuned to 32 htz, what do you guys believe the difference would be? more SPL? I really would like it to BOOM harder, louder, higher spl. Im not into SQ so if that goes down thats fine. Also Is there a difference in sound from building a box from 3/4" mdf then going to 1" mdf ? This is a pic of the box I have right now. Thanks in the future for the input and help.

Just noticed that Johnecon2001 had the link to 12volt.com... That site saved my ass acouple of times, its great......I know your port should be over 2" wide. Thats what I maid my at and you can hear port noise. Not inside the car but when I pop the trunk you can hear it.

So what is the problem with the RE audio calculator? I wish it had more options, but i dont see what the problem with it is?
It calculates volume wrong so that throws off tuning, another problem I've seen with it is you can make the port to long for the box. ie you can make the port end up being 2.5" from the side wall of the box when your port is 3.5" wide, which will mess with tuning calculations.
What do you guys think about the box/port calculator on the site 12volt.com ?

Thanks , thats a good techninal way to describe it. Maybe if I ever have time I can build a box to hear the diff, its allways fun to play around with car audio..If anyone has done this please let me know what happend.. thanks

I was doing some thinkin this week. Can you guys help? So I have been running 1 ssd 12d2 in 4ohm off my alphasonik1200da, not in 2 ohm because my weakass alternator only has 85 amps altogether. I have a 60 amp fuse in line and it has never blown. So I figure im getting about 40 to 58 amps to the alphasonik at any given time. So thats about 400 to 650 watts of power at best to the ssd12. My box is on the small side at 1.6 cuft with the sub in it tuned to 34 hz. I plan on getting a high output alternator in the future. My question is a hard one to describe. Would I get a noticeable difference in sound? More bass ? How much more bass would you think if the box was around 2.2 cuft at 32-34 hz.... If its alot more output I might not need another ssd, at least for me. I know I can just build the box to find out but thought I would ask your opinions first. Thanks..

We found this place in south west oregon on are way to the redwoods.
He's right at home in the northwest
This place is great, and the pics just dont do it justice. They have trained most of the cats to
roar on command and you can feel it in your chest.

You want some more you got it..
This lake is 4 x 6 miles around, the drive around is 33 miles .
The pinnacles, about 10 miles from crater lake. They are taller then you think.
top right corner
Great camping and so much to see. With all the view points to stop and take pic's it took us 9 hrs to drive around the lake,
and thats just starring at the same lake from some where else. I could'nt stop..The average rim is 1,000 ft above the lake with a peak of 2,000 ft lets just say
my woman was'ent going to walk it and I think I would of been hurt'n since were 7,000 ft above sea level.
The next day was the pinnacles which can be 100 to 200 ft high , their amazing and bazzar at the lest.Did not see any bear thank god but saw a couple heards
elk and some deer, and alot more. Thanks...............

I'm a little late on the thread but had to look. I absolutely love these car's they are so much fun. My second car was a 90' gt lowerd and being a bass head since before I even had a car I had to put 4-10" orions in it off a rf punch150 hit 142.2 at the dash , I thought I had it all bass, speed and handleing.. Loved it but had to sell , to many tickets it sucked so bad , had it for 60,000 miles though. the best tires are the firehawk sz50 insane grip in wet weather. So when all the tickets came off I bought a 91' lx with a saleen body kit , a friend sold it to me for $2,200 in 2002 . kinda beat up but , did I say I love though's cars.. I kept the fiberglass box I made for the 4-10's and just refaced it for 4-12" Jl's and ran a kicker zr600 to them I never had it metered but it was great..They handle so good its sick!! Thoughs where the days..Thanks for the memories........
