Okay, thank you. Il try making a box like that then.

okay, that got me the cubic feet... I already knew my cubic feet, i was looking for the 80-90 in2 like you said. How much is 80-90 in2 in cubic feet. 85 in2 = how many cubic feet?

I know what it means... I'm trying to find how much mine takes up now. 1.5 cubic feet = ??? In2

well you said to use 80-90 in2 of port... i just want to know how many cubic feet that is. because right now my original design has .64 cubic feet, and the newer one i designed today uses 1.48 cubic feet.. I dont know how those numbers compare. I am about to leave the house, I will download it later tho and try to learn

I had that once, didn't fully understand it. I'm afraid I won't know everything I'm looking at. Can I just get a conversion of 85 in2 to cubic feet? That will be my last question, with that I can build my box.

okay, so im pretty bad at calculating that. I only know how to tell how many cubic feet I have. So can I convert that? How close was I on my last design? (Last post on first page)

1500 RMS amplifier. Thank you for your help

This is another design of the same box. SAME outside dimensions. Total volume = 5.333 (1 inch MDF) Port Volume = 1.37037 Tune = 31.5 hz I made the port 4 inches in width and raised the length to where I had it tuned around 31.5 - 31.6 hz. Its now 4 x 16 x 37

Okay, so if both SA12 and Gcon 12s are both bad ass subs, il probably stick with sundown then. So 2 SA12s, in that ported box. I will make another model of it tonight. How big of a port are we talking? I will also change the box dimensions to keep around 3-4 cubes of air because sundown recommends SA-12s get 1.5-2 cubes each.

The 2 15 inch gcons sounds good. Won't I need a bigger box tho? As for the subs... I understand I need to pick, bit for this box, would sa12s or gcons sound better?

Well yeah, of course I want it to sound good. I just want to be able to crank it up and get some good bass. Not competition or anything like that, but just some nice loud bass when I want it. I just want to know if this box is good to use?

Sa-12s, or gcon 12s. Or possibly an xcon 15. Which ever is louder. This would be in the back of an SUV. Would the subs being on top be better? I could raise the height of the box and extend the port to what ever I need.

Total volume = 5.333 (1 inch MDF) Port Volume = 0.64 Tune = 31hz Box dimensions Total Box = 38 x 18 x 18 Port = 3 x 16 x 23 Is this a good design for a ported 15, or two ported 12s? If not, what needs to change? also, could the subs be mounted on the top? Would this effect quality or spl?

My friend has a small ported 10 on 250rms and its as loud as my two 10s sealed. He's ported at about 40hz tho. I'm going to try to get a box like that around 38hz at most. My best buy has something like it. I tested airflow of my ports and there's hardly anything coming out, and my friends box is pushing out a crazy ammount and still sounds good on moat music. I dont listen to anything to low anyway. 35hz is about as low as it gets

Okay, im going to look for a prefab box thast ported. maybe the same size as my last box but a little wider with a port. ​can somebody recommend me a box? My current sealed boxes are H=13.5, W=14.5, D=11.5(at the top) 6(at the bottom) The ported box I need can be as big as H=13.5, W=16 D=12

The person who built my box is a professional carpernter. He said he will be able to undo the glue, if the box won't be good enough with a slot port then I'm giving up until I get a new car. I will make a sketch of my box later today

My box won't be to hard to take apart. I just need a design to use. I have the two boxes already, but I'm not good at doing slot ports for boxes so small

I am going to use the 2 boxes I already have. Just replace the ports

My original design was a slot but I couldn't do it correctly without the funding of the box around 45+Hz. I want around 33-35. Can somebody Give me a design? Cause my aero ports aren't moving all that much air.

So how do you correctly port a box that's 14 wide, 18 deep, 7 tall in the back, 14 in the front?

Is that big enough to get an actual 10 inch box with port room

im working on it, looks like the biggest it can be is about 15 inches wide, 13 inches tall, and around 18 or so inches deep. But around 20 inches or so deep into my trunk, the height is a max of 8 inches.

haha yeah, thought so, thats why im waiting till i get a new car. About the trunk opening tho, im not sure about depth, but the tallest a box could be is 14inches, and widest it could be is 16 inches. and thats pushing it

^thats the case for me :/ My midbass is aftermarket Kicker 5 1/4 speakers. (stock size) and they dont exactly kick very hard. I was thinking about replacing them with tweeters, and placing a single 8 inch midbass behind my seats. (in the convertible 99-04 mustang, behind the seats is bare metal where the MACH460 amps are for the sound system and convertible roof motor lay. Its a very ugly place, but nobody would ever have to see it.

lol, yeah i think im going to lower mine to around 100hz... anyway, il try to get to measuring as soon as I can. I know the smallest part of the trunk entrance is 16 inches wide, and from there to the top of the opening is about 14 inches.
