Just as much as u can get without it effecting tuning so much

I'm having conceptual problems or I'm just brain dead or something tonight so it hasn't been very productive I apologize hopefully I can make more progress tomorrow.

Tbh I don't think you have enough room with your current dimensions because you're gross volume before any port or sub displacements and before a double baffle is only 12.16 manufacture recomendation is between 5 and 8 cubes ported. With no displacements and single baffle all the way around I managed to get 9.37ft^3 at 33Hz with 14.41in^2 per cube more tweaking could get you more port area but at the cost of volume and tuning maybe I'm missing some big clue but I think that's close to as good as it gets let me know what you think.

For my Skar VVX-10D2 I built the recommended ported box that measures 19x15.5x13. Its 1.44 cu.ft. tuned to 33hz. The space that I have available in the hatch of my 2012 Scion XB is 16x16x20. This will take up roughly 1/2 the cargo area in the hatch. Lookin to get a bit more oomph out of this Skar vvx-10. Perhaps later on I'll sell the Kenwood KAC-7205 and go with a Hifonics ZRX1200.1D which on sale for $159.
Again, I'd appreciate any design input you could provide. THANKS!!!

Which of those dimensions is height width and depth and will there be room for your port to fire rearwards if I draw it up that way or does everything need to face upwards?

hey i have a American Bass XFL 1244 wired to a hifonics brutus 1200.1 at 1 ohm. right now i have it in a sealed box but i would like to put it in a ported box but i have no experience with them. I am butting this in a 2004 Chevy S10 ext cab. my max dimensions are: height- 24 inches, length- 40 inches, and width- 18 inches. Ive also heard 3ft^3 would be good for this sub but i dont know for sure. I would like to have it aero ported with both the port and sub firing up. i would also like it to be flush mounted. I have no clue what a good frequency to tune this box to but from what ive been reading 33 Hz sounds like a good place to start with this sub. if you think differently let me know because im sure you know more then i do haha. I am going to be listening to mostly rap if that helps also. Im hoping to be loud but still have clean bass. if theres anything else you need let me know or if you have any suggestions let me know. Also thank you for taking the time to help all of us out. Im sure everyone really appreciates it.

I re-measured my hatch and it looks like the room I have available is 16" high, 19" wide and 19" deep. There is no room for the port to face rearwards as the box will be less than an inch away from the rear hatch interior panel. So I guess both woofer and port will have to go on the top. Just the way I have it now with the port up against the rear window and the woofer closer to the rear seat. I guess I could spare an inch off the depth (so its 18" deep) so that there is room for port resonance if the port were to face the rear. I don't know if under 2" between port face and hatch wall would work, or if it would just cause all kinds of port noise. The box I built (based off of Skar Audio's recommended design) has a port that is 11.5" high and 1.25" wide and at high volumes I get tons of port noise. Anyways, I appreciate the assistance and look forwards to any design. Thanks again!

Hi, a guy I worked with gave me a pair of Sony Xplod XS-GTX120LW 4ohm svc when he left the state. I can't seem to find specs on the sub for air space but similar sony's like 1.13 cf ported. I'm looking at getting a RF Rockford Fosgate R500-1D Prime 500 Watt Mono D-class Amplifer which should put out about 250rms into the sub (only using 1 12" in the pickup and the other in a old car for the wife, but that comes later). Looking for SQ with an occasional foray into some 80's or 90's rap. I am hoping you can help me figure out a box for behind the drivers seat of my Nissan Frontier King cab.

Looking for a ported box of the slot variety. I've got a table saw and know how to use it so 45's are no big deal. Also I will be using birch plywood as it's leftover from building a bookshelf and I never built a 2nd one or returned it to the store. It's about 18mm thick or .706" (not sure what the fractional is off hand I just used a caliper on it)

Rough space to work with is

14.5" bottom depth

16" tall

21" wide

9.5" top depth

I'm thinking of having the sub and bottom face 2" up from floor with the port firing forwards at the top of the sloped face. The box can go taller by following the same angle. Any help is appreciated as the only other times I ported my boxes I just called PPI up and they told me what the 4 12" pro's needed and I cut the pipe up.

If you could go to aero ports you would have more volume than you know what to do with. But it would probably nearly double the price of the build to go with any of the flared style ive found.

@raptor727 I had one drawn up before your last reply it was the only one that I've managed to do lately everyone else please bear with me I'll try and get some done today since it looks like it's going to rain. Oh and one piece is missing from the cutsheet try as I might I couldn't fit everything on one sheet all you need is the long piece of the port from a 2'x4' sheet or something and you'll be golden.

RE XXX 15 3.6ft^3 32Hz 14.88in^2/ft port.

I have yours finished after running the dimensions of your last box through torres your box was under a foot cubed after port and subwoofer displacements so that could easily explain your lack of output and port noise.

Sundown x-12 powered by saz-1500v3. (Sub cutout is 11.09" and about 10" deep maybe)Max dims: 32w 15.5h 15d tuned between 28-32hrz

Sub n slot port back with double baffle ( 1" sub mount thickness, 1/2" flush mount thickness)

Also would like symmetry so either one port on each side or a single port running along the top or bottom

If you could do that it would be awesome and thanks in advance

I ran in to a problem when attempting to draw yours when doing a port on each side of the sub the ports would run into each other along the back wall I'd recommend a single slot port or possibly 2 aeros but I'm not positive that aeros would work since I didn't check.

@autobotguy here is your design and cutsheet I forgot to draw in the 45's but I', guessing they'll be an 1.5-2 inches wide.

Skar VVX 10 1.5ft^3 33Hz 14.93in^2/ft





@DbDesigns You'll need more than 1 sheet since it wouldn't all fit on one piece.

4 SA 12's 7ft^3 32.5Hz 15.4in^2/ft

Alright so it's looking like 47w x 31h x 47d give or take an inch on each but it shouldn't take that much room for 2 15's I'll try and get yours done tomorrow since you've been waiting a while.

what if instead of L ports on each side u did U ports labyrinth style so they dont run into each other
