Can i fit these 2 12s in my car (proper box size help)

[TheCurator]

So i talked to 2 local sub box builders and they both told me either no i cant fit it or that the sites spec sheet makes no sense and the subs must be ****. So here i am.

I want to fit 2 B2 Riot 12s tuned to 34hz in my 2010 forester (on 1600 watts roughly)

My Desired working specs would be
L:13in
w:40in
H:15.5 in

if needed i could spare 2 inches in length but the original specs allow me to run an 8 inch amp rack in front of it, keeping the port at a nice 8 inches from the hatch. Ill link the subs below if it helps

Im just trying to map out a damn build but this box appears to be the stalemate in my process.

If needed i have no issue dropping to the 10 inch but id like to do the 12s and i used to run 2 SA-12s in an outback with no issues

The B2's want 1.65 cu ft net (prior to woofer and port displacement) so your box would be close but a bit too small.

Are flexible on the size? There are better options out there for less money than that particular B2. At a little larger box of 3.7 combined net,you cold get into a pair of these at only $198.04 ez.

Tune the box to 29 hz, get a Taramps 3k, slamm'n!

Do you have any room to work with on the height? This is a mockup I made using free software (not best the best but good for reference) the only issue is that you will be missing out on a lot of output cause the box will have to be tiny. This is using the absolute minimum airspace specs for those subs(1.4 cubes each) with about 23 square inches of port area.

after seeing you guys replies, honestly how much taller would i need to go ? i in reality could go taller, i just measured up to where it aesthetically looked nice along my back seat. I'm super interested in these B2s so im trying to not let those other people tell me the spec sheet doesn't make sense haha! and if it matters i do want to run subs up port back ideally. I just love how that looks . im not trying to go crazy with this build so i definently don't want to run 3k. This is a more SQ build than SPL. I thought the 1600 sounded like a good pairing for them but being told they wont sound good at that level confused me even more. I almost feel like i was trolled haha

If you are looking for a SQ built, you'll need a smaller box tuned lower. Those subwoofers with massive magnets and motors like most B2 subs are in efficient AF and are designed to be used in massive boxes with 2-3x rated power . B2 is an SPL brand they are meant for getting loud at the cost of sound quality.

If you are looking for SQ but want it loud, pick up a couple of those VCWs Doxquzme mentioned and put em each in a 1.25 net sealed box. They will beat your car up. Check out EXOcontralto on YouTube. He did a build with two of them in a sealed box for his girls car. He even used old versions and they have come out with several revisions since so they are even better

If you can go 2-3 more inches taller and a.couple inches deeper, you could make a nice ported box for an SI SQL 15 inch as well

honestly these sound nice ! (the SQ series), i cant find power info on them but reddit bros are throwing 3k at them it seems. Im curious how big of a box id be looking at if i did 1 12 ported or 2 10s ported with these models?

Would taking a SQ 12 and throwing 2.5k at it sealed be ideal for dubstep music? or would i maybe want to look towards 2 10s ported to 34hz pushing 1600 watts? ( i can wire to either with the b2 2.5k amp i was looking at) i fear if i go sealed i wont get those low lows . But honestly the price range i can handle so lets discuss if you guys are down. It seems everyone talks me away from the b2s so **** it lets look elsewhere!

as for size i can definently give a few inches to the height but id prefer to keep the 8 inch amp rack for if i do go ported. If its sealed than it wont matter anyways since itll be a smaller box by default .

Music tastes Are dubstep (typically in the key of D , 37hz root sub) , nu metal like slipknot , and also the new falling in reverse album hasnt left my shuffle in ages, for reference points!

Yes and no. I wouldn't make a habit out of pounding an SQL like that on the regular. Id say you can easily daily them 1k-1.5k (Nick the owner of Stereo Integrity also mentions this on the Q&A page but says you void warranty as they are only rated at 1k RMS)

But yea a pair of those on a 2k will be great for daily bumping but that is well past SQ territory. SQ means all the frequencies are mixed and balanced. In a SQ setup, the subwoofers goal is to "disappear" into the rest of the soundstage and if implemented right, you would never know think there is a subwoofer cause it will sound like the bass is coming from the speakers. This is how it is in my GFs truck and I love it, vs my Jeep with an 18 inch sealed (also Stereo Integrity, the HT-18 model) on only 500-600 watts and it easily overpowers my door speakers and muddies the sound stage(granted my door speakers are cheap infinity components I threw in there just to have music when I first got the Jeep). You're gonna need some pretty good door speakers that are able to keep up with the subs. I had two Skar SDRs in a small ported box on only 600 watts and even then they overpowered the **** outta the door speakers

Don't be scared of losing lows. With those subs Ina sealed box you can completely turn off the Subsonic filter allowing them to go down to 8hz like they are designed to. You can use EQ to bring it back. I downloaded Poweramp EQ app on my phone (free 32 band EQ and gain boost for low voltage RCA outs) and brought back all the low-end I lost from switching to sealed.

thats fair i guess my goal is to feel the boom without blowing the car apart. Im going to be running some morel Tempo ultras on 130 watts for the front stage, but im not dead set on totally blending the sub fully (i could with the bass knob if i wanted), so i guess maybe im aiming for a nice in between ? im not trying to push 4k watts like alot of people. I guess i could always do with what i know and run 2 Sundown SA 12s again, but i fear id run into the same box issues with the b2 box idea? I had those tuned in a box at 33hz using a jbl 1400.1 and it was literally perfect for what im after now, so im in a sense trying to recreate it with a slight upgrade, thats how i found the b2 subs and thought they might be perfect for that

The SAs are very comparable to the SI SQLs. However, the SQLs are more efficient and have higher motor force so you can use them in a smaller box. SQLs are a good mix. You can turn down the gain and blend them perfectly with the speakers if you feel in the mood in a particular day and the rest of the time when you want to really bump you can crank it back up to your liking.
In my opinion SQLs are the perfect subwoofer for really any application. They also work great for infinite baffle as well. You can put them in a large ported box tuned super low and use them for home theater even. The possibilities are endless really.

You listen to dubstep which has a lot of transients (going from start to stop and vice versa, which pulls a lot of power and requires a lot of excursion especially when doing lower end transients) which the SQL is perfect for since it has 2 inches of distortion free excursion. Sealed boxes also are also great for transients because the subwoofer uses the "air spring" from the pressure inside the box to help move the subwoofer, where as in a ported box, you'll need more power or motor strength to move more air cause there is less of an air spring effect.

Tldr; 2 SQL 12s in a 1.0 cubic foot net sealed box each on 1-1.2k is a match made in heaven for you. There would even be enough room to add a third one too if you think you need more and sealed boxes are cheap so you don't even need to pay a box builder hundreds to build a custom ported box. $100 prefab dual sealed box from Qpower or whatever their name is and you're golden

If the SQLs are out of your price range, the 12 Dayton Reference HO also works well in limited space.

edit: i just noticed my reply to him never posted last night ... but yeah im not trying to full blend the subs into the mix of the car, i want the ability to sound slighty "ghetto" if i wanted to. Thats why im trying to run a port

There are tons of high quality subs out there. You need to backwards engineer things. Figure out what size enclosure you can fit and then find the sub/subs that work in that airspace. For most 12s figure on ~2cuft net, tuned to ~35hz, probably ~3.5cuft gross.
