2 sa 15s v3s I have these dimensions to play with. external height 23.5 external width 49.5 external depth 16.5 basically a slot port enclosure behind the front seats port and subs facing up or inverted if need be for space I would probably run these off of a skar 2500

It seems like I am having alot of trouble wrapping my head around mounting 4 12s in this space. Would it be much easier to do say two sa 15's. Would It be as loud on equal power per sub? Thanks.

So it is an l port with 10 inches on the second part of the L if that makes sense so 37.5 is the length of the port. I am also playing with the idea of trying to do one long port the width of the box and mounting all subs on top. If I made the box 17.5 deep than I could do a 2.5 inch port that is 48 wide and with an 8.5 inch l it would give me 33.25 port length with 7.45 cubic feet in the box. I will have to measure if I can extend the length a bit so I can make sure there is room to mount 4 12s side by side on the top baffle.

So I came up with a box that is external height 23.5 external width 49.5 external depth 16.5 and has an 8 inch port 124 inches of port area. box volume 6.771 tuned to 32.5 hz my plan is to run two sa-12s inverted on the top of the box and 2 mounted on the side of the box facing the front seats in my 05 dakota club cab Does that raise any red flags for any of you guys or does it sound like a decent idea?

Awesome thank you

Yeah I don't see port area anywhere on there. Unless it has some name I'm not familiar with. Thanks.

Hi guys I think I'm going to try and design a box for 4 of these with a slot port. I'm probably going to use the RE box designer and i was just wondering how many inches of port should I use for four of these subs? Or how many inches per sub? Thanks.

Does anybody have any input on a box design for this setup? I try using the Re box calculator and can set up a box with those dimensions and tuning but I know it's not the best resource for designing boxes. I appreciate any help or if anybody could point me in the right direction. Or maybe I need to post in another section of the forum? Thanks again.

You know I'm not quite sure. It was designed by Joe-x on here. The 7ft spec is from his design so I assume he accounted for at least the port. I think it had 100 square inches of port.

Yeah I'm talking 4 12's. At the reccomended 1.5 - 2.0 per sub I may be alright.

two minutes and no replies yet? Just kidding of course because I see that shit all the time.

In my last box those dimensions gave me 7 cu ft BTW

Hi Guys, I currently have a Sundown Sa-12 d2 v3 running off am NXV JAD1200.1 with big three upgrade and 0 gauge wiring. I am wanting more, which I'm sure is a concept you guys understand. So My plan is to run a skar 3500 or similar amp with an upgraded 250 amp alternator and extra battery of course, to 3 additional subs. Now what I am wondering is if I do a slot port box with the port facing up is there room to do two subs on the top and two facing the front seats? I was originally going to go with two sa 15's and a 2500. But I like the idea of more drivers and more surface area. Here are the dimensions I have to play with. I had a box for two 15's that fit in there perfectly using these external dimensions. external height 23.5 external width 49.5 external depth 16.5 Is it safe to run them on different panels like that? I am also thing about running the top two inverted for slightly more more box space (and to look cool) I appreciate any comments or designs or suggestions that anybody throws my way Thanks

I will probably see if i can find somebody who has one. I'm on a pretty tight budget and have some other gear to buy so one of my own probably wont happen for a while. They are great tools from what I've seen and heard.

Awesome I will just do it like I did before. Run a 50hz test tone and do it by ear. Thank you sir.
