Great prefabricated box



Sound Ordnance™ Bass Bunker

Shawn from Syracuse, NY on 11/4/2016

First of all: all you people comparing the sound of this box to a sealed.. stop right there. You can't compare the two. People who are looking for SQ aren't looking for a ported box so what your doing is really just pointless. Now, let's get on to the box. First of all, I gave it 4 stars just because it's not the best sounding box I've ever heard but it is actually just fine for what you're paying for it. I've found the ports are tuned to around 65 hz so this box isn't going to get super loud playing anything under 50. That said, I scored a 138.3 from this box (65hz of course) on 2 Rockford p1 12s on a 500 watt alpine amp. This was in a trunk system with double layer sound deadning. The seats were up too so I could have gained another db or so by putting them down but numbers wise that is what you can expect out of this box. I wouldn't suggest placing any woofers much bigger than what I have because they won't match the airspace inside and they will be underperforming. If your chasing numbers, I'd go with something alittle bigger but if your just looking too add lots of bass.. grab this box it's very solid and good price. Also make sure to grab some female spade connectors if you don't want to solder because they do not come with the box.

Pros: Price.

Cons: Ports tuned kind of high..

Great sound

This ported box really gives you the hard hitting bass you want from a sub woofer. It made a huge difference compared to my old, sealed box. It comes with thick wire in the box to connect your sub woofers. Definitely worth the money spent.

Pros: So simple to install subwoofers

Cons: Very large, didn't fit in my trunk so I had to leave it hooked up in the back seat.

Solid and Good Looking

Randall from Fort Worth on 3/29/2016

Crutchfield Customer Review (What's this?)

I've purchased two other enclosures from Fry's and the quality and look of this enclosure is far better at a more reasonable price. I probably didn't need the ported design but I went with it anyway. I got this one as a scratch and dent and I couldn't find anything wrong. Crutchfield is a super solid company. And free shipping. Enclosure holds two kicker 12" dvc. I have them wired down to 1 ohm in parallel. This thing thumps. I turned down the crossover to 80hz to tighten it up a bit. Would buy again in a heartbeat. Easily worth 25 % more than what the price is. Takes up some space for sure but I'm going to mount a small plastic tote to the top for carrying around stuff. Just probably not eggs unless I want them scrambled in the shell.

Pros: Quality, looks, sound.

Cons: None.

Sean K. from Louisiana on 11/25/2015

Decent box for cheap or small subs i went from an old sealed box to this and figured it would be better because it was ported got it and put my subs in and didnt get anywhere close to the sound i got out of my sealed box i was getting 26-40 hertz in my sealed box and this box couldnt even compare i guess ill keep it and mess around with my equalizer and try and get this box to sound better hopefully i can make this box competition worthy cuz sofar its not

Pros: Fit subs perfect

Cons: Sounds like crap compared to my sealed box

This is my first ported box, but it does not fail! It makes my twenty year old Infinity Kappa's sound amazing! Of course they sounded awesome in my old box as well, but that box didn't fit in my hatch. As it is, I would by this box again if I ever needed to install more subs in another vehicle!

Pros: Very well constructed and it puts out a great sound in my hot hatch!

Cons: None

Crutchfield Customer Review (What's this?)

I did a lot of research of what sub boxes for my Alpine SWR-12 D4n's and came across this box and glad I did. First the price is very affordable and the specs matched my subs and is very well constructed. It's looks better in person i thought it was a light gray but it's more like a charcoal grey which is a plus. Finally the subs sounds great in the box I'm currently running an amp that's only pushing my subs at half power and the bass is still pounding it's scary to see what's they will do when I get the right amp. Overall great buy. Thanks Crutchfield

Pros: Price, not too big

Cons: None

Best box ever!

Shipping was quick. This box is awesome. It sounds great with my Two 12 inch kicker Subs in my 07 Pontiac G6 and my 01 Dodge 1500.

Pros: Sturdy. Not super heavy. Sounds great. Smaller than most prefab boxes.

Cons: At the moment I have no issues with this box.

This box is very nicely constucted, and sealed very cleanly on all edges and corners. It defintely looks like it will last a long time. As for performance, this box had the airspace measurements I needed for my subs and I couldnt be happier with the sound I get from them. Low notes are low and fast beats are still very clear and consistent. Great box!

Pros: Good construction Great sound

Cons: None

This box is the best box I have had yet. Great size to fit in my 2012 Dodge Avenger. The box I had previously was very tight fitting in the trunk compared to this one. The sound is better quality as well!

Pros: size

Cons: none

This box is really great. It dramatically increased bass output. I didn't really hear much of the negative side of ported boxes as far as "boominess".

Pros: Cheap. Loud. Pretty.

Cons: Weird carpet. Angled back. Port placement.

Works well and displays nice. Very secure. Able to handle heavy duty screws to allow subs to hit how they are supposed to. Recommend.

Pros: Positioning of ports and ability to not break.

This enclosure brought my Punch P2 12's to life. I had a sealed box under the backseat and it didn't do my subs justice. I couldn't really push them without them bottoming out. I lost a little room on my backseat but It was worth it.




Austin from Wisconsin on 3/20/2014

I bought this box for my 95 accord. The box fits perfectly in the trunk. It sounds really good, and the ports are tuned pretty good.

Pros: Sounds good. Box is a good size

Cons: None!

Crutchfield Customer Review (What's this?)

Will have to say I'm very pleased with this subwoofer box. I replace a sealed enclosure with this box and it dramatically improved the bass in my car. Can not recommend this box enough. Much better option than buy a new amp and subs which was going to be my next option

Pros: Very solid. Bass is very tight and punchy. Very nice terminal connections

Cons: None that I can think of.

I have 2 sony xplods (1300) watts each an i only have them hooked up to a xplod 2/1 1200 Watt Amp and this ported box still kicks butt

Pros: Great box! I dont see why the price is so low an its fits perfect right into my trunck

Cons: None at all

Crazy what difference a box makes

Jbrown57 from Monroe, OH on 1/10/2014

Crutchfield Customer Review (What's this?)

This thing is amazing! It's not to heavy even with the subs (at least with mine) and fit perfectly in my trunk (03 CTS). The 2 Alpine Type R's sound amazing in this box (SWR 1221D, older 2 Ohm 300RMS) and the install was easy as could be. I defiantly will recommend this brand of prefabbed boxes to others

Pros: Lightweight for size and amazing sound

Cons: A small port between the 2 chambers would be nice for wiring the 2 subs together

Crutchfield Customer Review (What's this?)

Ok so i had a huge box and i was looking to save space but still keep the same BOOM! I went from over 4 ft of cubical space box in the back of a 2000 Honda CRV, holding 2 12in. Orion XTR Pro's. 1000 peek watts, 500 RMS handling power with a 600 watt Orion amp pushing both, sounded alright. But then when i installed this box i don't even think i need a better amp cause its just killing my ears !! Love this box don't think i will b changing it anytime soon and would defiantly encourage others to buy it!

Pros: Doesn't take up much space Slams like Heck!

Cons: The wires that come in the box are basic 16 gage wire

nice box!

There is nothing negative I could say about this subwoofer box, I have a set of 12" Rockford fosgates T1's and it's perfect the way the bass hits in it it's incredible, I use to have them in a ground shaker box, but the bass wasn't as deep, then one of my boys got one of these on his system and I said what the heck I'm gonna try them, and man what a difference better sound quality and cheaper price than ground shaker. Keep up the good work Crutchfield.



Good Value Box

Mason from PA on 4/23/2013

Crutchfield Customer Review (What's this?)

This is a good box and works exactly like it says it will. The only have 2 complaints about it though. First thing was that the box did not come with any screws for the subs. I am not sure it that is common, but the subs i bought did not come with any either. The other being that the speaker wire in the box is standard wire, and it is soldered on so it is a little trickier to switch. I would think that you would want something bigger gauge.

Pros: Good Value Well Built

Cons: Does not come with screws Small gauge speaker wire

Better modified

Kade from Leamington, UT on 4/9/2013

I bought this box because the specs fits the subs I had at the time and it did ok. But then i bought some new subs and they didn't perform very good (it was a little small but still within specs). My friend had the same sub but in a box that was 1.7cuft which isn't too much bigger and it sounded a lot better, and the other box was cheaper. Then I realized that the specs sealed was perfect for my subs, so I sealed this box and I am very impressed with it now. Sounds a lot better, even better than with my first subs. Maybe I just had subs that were terrible for the box, but this box shouldn't have a lot of difference in specs between other boxes when they're both designed to work fairly with all subs. First subs were Kenwood kfc-w3012, 2nd kfc-xw12. I know they aren't the best but they get the job done for now. 3 stars ported, 4 stars sealed.

Pros: Love the internal braces. Hardly any port noise at all if any. Good build quality.

Cons: Didn't perform as well as other boxes that were cheaper.

Ad some power to your car audio arsenal!

Cameron S from Greensburg, Pa on 4/4/2013

Crutchfield Customer Review (What's this?)

I purchased this bass bunker box to replace a sealed attrend box that I had my two alpine type r 12s in. The old box was causing one of my subs to bottom out on certain songs so I wanted a replacement and I figured why not ad a little output by getting a ported box? After doing some research I ended up at Crutchfield because they have affordable boxes that seemed to be well built and had the perfect cubic footage for my subs. I purchased this box and it arrived very fast! After installing it and a week or so of listening and tweaking it's definitely louder and very clean! I would definitely recommend this box to anyone who needs a sturdy, high-quality box at an affordable price.

Pros: Perfect cubic footage after sub displacement. Ports tuned to a good even frequency range. Sturdy 5/8" mdf construction. Separate chambers so can be used with one sub and upgrade to two later.

Cons: None

Great enclosure delivers quality bass at lower and high volume, The material is pretty solid and is got excellent appearance, Only reason I'm not giving it 5 star's is cuz I herd better ones before But they were twice the price.

it works great, i have two low end pioneer 12's and they def sound better in this box than the two sealed boxes i had them in. the biggest differences i notice are sustained bass notes sound clearer and when there's two different frequency bass notes at the same time, it comes through better (idk the technical terms)...the free shipping was great, ordered it early Wednesday and it arrived Friday...overall i have no complaints...

Pros: Proud to have sound ordinance in my vehicle .

Cons: None found yet.

Excellent Box

Larry from Portales, NM on 7/25/2012

Crutchfield Customer Review (What's this?)

First of all, this box was cheap dollar wise as far as dual ported boxes go. Normally, for this price you will get a mediocre box at best, this box, however, is the exception. Recieved it in a week, installed it immediately into my 07 honda accord. Sounds great with the two Boss Audio Phantom series subs I have in it. All in all, a great buy.

Pros: Well built, completely siliconed interior, carpeting was done very well and has nice clean look, price is cheap, fit perfect in the nook of my trunk against my back seat and had clearence to install the amp on top of the box.

Cons: None that I know of.

Crutchfield Customer Review (What's this?)

First off i would like to say thanks to Crutchfield for being based in VA because all of the shipments come fast! Now about the box. This company right here knows how to make their boxes look great and sound great. I was a lil sketchy of buying this box until I read the reviews and boy were yall honest and right. This box is awesome! I put 2 Kicker CompVR 12" subs in there, wired them correctly, and have a 1500 watt amp pushing explosive power to them and boy do these things bang. Also, the box looks so great in the trunk of my 2000 Jeep Cherokee. Doesnt take up much space looks great with the Kicker CompVR cause of the color (which is black and gray and the box is black and the SO logo is gray) and also it matches perfect with my jeep cause its also gray. I am proud of this purchase, thanks Crutchfield!! and also thanks for putting Sound Ordnance on the map with all the other big companies! Go VA!!

Pros: Style Sound Fabricated Shape Size

This IS a 5 Star Product! Don't listen to bad reviews!

Lucas600rr from Pa on 4/3/2012

Everything about this box is 100% 5 Star Quality. There is a certain review on this products page from someone that, if you couldn't already tell by the words, spelling, and measurments, must be a very young and/or very intelligence-challenged!!! These are high quality production spec. boxes which are most likely premade at a production facility and are not custom/made to order, which anyone can tell by looking at the product page. Also if for some reason you should happen to have subs that are soooooooo much different than every other sub on the market for the past 30 years, then you would most likely already know that a custom made enclosure would be required when you bought them because they would be so rare that they almost wouldn't even exsist! I would recommend this box to anyone looking for a high quality production made sub enclosure to mount any standard production made subs. In a word AWESOME!!!!!!!!!!!!!!!!!!!!

Pros: Everything about it! Fit, finish, construction, materials and operation, are all great. Also very reasonably priced.

Cons: Non as of now, which is approx. 8 months.

i ordered this a while back (November) and i think its the best box i have ever had!! it was delivered to me in like 4 days, which i think was great. i would recommend this box because it doesn't rattle and the ports are a blast as well.


Cons: none its flawless

Almost a nice box.

EricD1234 from Quitman, GA on 12/14/2011

I'd like to start my review with my call to Crutchfield inquiring about this sub box. I asked if the box could be made to different specs because my subs are different than most. I was told no. I wanted to have one inch of mdf for the front and to have 11 1/14 inch holes cut to fit the RE Audio SEx12D4s I was getting for my nephew for Christmas. I was told it wouldn't happen. So the box is very close to the specs I needed so I ordered it. First the speaker cutouts are 11 inches, not 11 1/16 inch like they say. So I'm going to have to cut this box so the subs fit, wonderful. Second, that is some seriously cheap carpet, in spots I can see through it. I would think twice about getting a box built if it weren't so close to his birthday and Christmas. Please understand my rating, I used to build better quality boxes at home with carpet and glue.

Pros: The box size is quite nice.

Cons: The speaker holes are NOT cut to 11 1/16"!!! They're cut to 11"! <br> <b>[Editor's Note: Thanks for your review. We asked our product research team to double-check the measurement of the speaker cutouts. They pulled another box out of stock and measured each opening at four points. All eight measurements were 11-1/16" or ever-so-slightly larger than that.]</b>

Jus10o from DFW, Texas on 6/1/2011

Crutchfield Customer Review (What's this?)

This is a very nice box. Its very clean looking and is visually appealing with the black carpet and design of the box. The box worked out perfect and fix snug into my trunk, its cubic feet for each side was very close to the recommended specs for my subs. It made them sound/hit so much harder. I would advise you measure the opening to your trunk to see if it fits. I measured my actual trunk space and it fit fine but I didn't think about the opening. I had less then an inch of space when putting it in. Overall if your are looking for a simply sub box I would recommend this to anyone.



perfect buy

Leonitus from Thatoneplace, IL on 5/27/2011

Just bought this box on Monday, it showed up Thursday so thats great all by itself. Hooked 2 alpine type R 12s up and they sound pretty good. I cant judge it too much til I get a bigger amp, but definitely a perfect buy.



So far so good

Crutchfield Customer Review (What's this?)

I just bought this box not too long ago and my subs haver never sounded nicer and louder. Right now I am optimistic that the box will hold up and not slowly disenegrate like my old box did. At the end my old box rattled and I had to put in copius nails and screws and it still rattled and now is worthless. It was an inferior dual 12" box that was bulit for a one 10" sub with a 250 rms amp. I hope this one hold up.

Crutchfield Customer Review (What's this?)

the day i got this box i immediately got my subs out and installed them. i also got out the amp and i had the room, so i screwed on the amp to the top. it's got an angled back which is perfect for a car box so it doesn't get blown back. if there was anything i had a problem with is that it only has 16 guage wiring on the inside. 16 is decent, but if your looking to put more than 1000w in each hole, i recommend jus getting some 12 or 8 guage wire, it's a good investment. Overall, excellent product, i looked at 7 different brands and this was by far the best choice. HIGHLY RECOMMENDED.

Wow, great box exactly what i expected. but above that crutchfield, hats off you go it here through a storm a day early with no problems and a handy guide. great customer care. you should open a customer support class to teach people how its done. 10/10 you just won my business



Solid Bass Bunker!

Lino from Chicago, Illinois on 9/30/2010

Crutchfield Customer Review (What's this?)

Bought and installed this box, it's very solid and my 12" Alpine Type R's fit perfectly. As long as you configure your subs properly, you will need nothing more. The box is great. The material is very strong and looks very durable. If you have space for it, my recommendation is for you to try this box . Awesome price, excellent box.




Hands-on research

Product Research


Materials: The Sound Ordnance BB122-175V Bass Bunker is an unloaded, hatchback-style ported enclosure for two 12" subwoofers. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet.

Internal Box Volume: The enclosure has two separate chambers, each with 1.615 cubic feet of airspace.

Terminals: The BB122-175V is equipped with two pair of spring-post speaker terminals, one for each chamber, mounted in the rear panel. The spring terminals will accept bare wire up to 10 gauge, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure, each set of terminals has an attached 24" length of speaker wire for connecting the subwoofer.

Brackets: Brackets for securing the enclosure to your vehicle are recommended.

I received tremendous sound from the sub box and the subs that I had. The box fit inside my 2012 Fusion and still had plenty of space for other things. [ Lorenzo  Mar 01, 2017 ]
Tons of research resulted in me buying this prefab box. Although i have the knowledge to build my own, i do not have the time, so based on reviews, will give this box a shot. [ Daniel  Feb 20, 2017 ]

21 questions already asked

The subs might not hit the lows like they should. [ Marcele  Mar 29, 2017 ]
I have two old green dual voice coil Infinity Kappa 12's in this box and it makes tons of bass. These speakers are twenty years old or so and I am having a hard time finding their space needs and I'm not a sub guru, but I would guess you could get by with less room if your box is ported like this one is. Mine are wired in parallel as a one ohm load on a 20 year old Lanzar Vibe 400 watt amp and I had to turn it the amp way down to keep from hurting my head. Granted, all of that is installed in a hatchback so I'm sitting in the same room with them and I am loving it! [ Dustin  Mar 27, 2017 ]
1.6 isnt that far off from 2 and this box made my subs hit so much harder than any other box ive tried the quality and clarity of this box is amazing [ donzel  Mar 26, 2017 ]
I'm probably not being very helpful, but I have a honda CR-V and this box takes about half my trunk space. I would measure the trunk if I were you because the box if pretty big. [ Sydney  Feb 11, 2017 ]
Not really sure ik it's a tight squeeze in my 2004 Grand Am but it does fit.. I put mine in my backseat idc what anyone says its way louder in the back seat lol [ KYLE  Jan 31, 2017 ]
I have a 2000 Honda Civic ex and it fits in my truck and both of those cars are in the same generation of hondas so I would say so [ Joseph  Jan 31, 2017 ]
yes it will fit [ JULIO  Jan 31, 2017 ]
Yes it will i had a 98 hatch bumped just fine [ Christopher  Jan 31, 2017 ]
You don't have to do anything to it. It won't rattle. You can put a pillow in each side to muffle it a tad; two 12s in a ported box in a small space tends to overpower the rest of the music [ MIKE  Oct 09, 2016 ]
Filler makes the sub "think" its in a larger enclosure than it really is. Just remember, these boxes will NOT give you the best performance from your subwoofer. They do however, work well enough for most people. No rattles with my enclosure either. [ shawn  Oct 07, 2016 ]
Yes it will I have a 97 honda accord and it's a great fit. [ Joseph Andrew  Oct 07, 2016 ]
It should fit no problem, it's a fairly small enclosure and you should have no problem getting it through the trunk gate. In the event it doesn't the backseat in a Honda Civic comes out very easily and you could go through the back seat into the trunk. But I seriously doubt you will need to do this. I bought this enclosure for someone else to do an install so I can't speak to how good the box really is but for the price point I suppose you can't really go wrong. I always prefer to build my ported enclosures around the specific subwoofer and achieve an optimal tuning whenever possible. [ Hidy  Oct 07, 2016 ]
Thanks for your question. For fit and information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Kenny  Mar 04, 2016 ]  Staff
I bought this box for my 2 12" Alpine type R subs. They fit perfectly and worked very well with my Pioneer GM-D9601 amp. The amp pushes 1200 Watts RMS at 1 ohm, although I am currently running it at 2 ohms and receiving 800 Watts RMS. This would be plenty of power for your subs and I highly recommend getting this box and that amp. [ AUSTIN  Mar 05, 2016 ]
I have two 12" me woods in this same box with a 1000 watt cheap amp and it sounds amazing! For the price of the box it is a really great deal. Not regretting at all the buy. [ Jorge  Mar 04, 2016 ]
Do you mean Alpine Type R 12's instead of Kicker? But a 4k amp should be fine [ Marcele  Mar 09, 2016 ]
I have a similar setup and found that I could not be more happier with my decision. The subs are still tight and the sound is great with all types of music. [ Lorenzo  Mar 05, 2016 ]
I have this box in a 2014 Ford Focus hatchback with two Infinity Kappa 12" subs and a 400 watt amp in a one ohm load. The sound I get out of this too much really, but it fits into the hatch very well. I do not know much about the Mazda 3 but I would guess that the biggest issue would be the mouth of the trunk. If your car is a hatchback I wouldn't think this box would be an issue. If you are just worried about the sound, this box puts out! Just do not cover the two triangular ports and you'll shaking the mirror off of the windshield in no time. [ Dustin  Feb 29, 2016 ]
If you mean an Alpine Type R- it is a little bigger then recomended. If you mean a Kicker CompR then its alittle smaller then recommended. Either way these subs will both put out a good sound. May not be the absolute best they could have but i think youll be satisfied with this enclosure. i had 2 boss 12s and 2 sundown 12s in this and i was pretty happy. no leaks or issues at all. [ Roman  Feb 29, 2016 ]
I bought this enclosure. Decent quality. Unfortunately, the port dimensions are not right for the type R. I would recommend having one built or look on flee bay to find a correct enclosure for these subs. They ARE picky about what enclosure they are in. [ shawn  Feb 29, 2016 ]
12 gauge [ JOSEPH  Dec 20, 2015 ]
I can't remember but it will work. I had 2 alpine type r 12 inch subs in mine. And they are rated at 1000rms a piece. [ JEFFREY  Dec 18, 2015 ]

That will depend on how large your current box is. This box is pretty compact for a dual subwoofer enclosure. For information on comparisons I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Jeff  Dec 06, 2015 ]  Staff
Yes. This box will work with two of the Pioneer subs. [ Jeff  Dec 03, 2015 ]  Staff
Yes they are [ EVERETT C  Sep 16, 2015 ]
In my opinion this box is great for any pair of 12s [ JEFFREY  Aug 23, 2015 ]
NOf sure about those but I use that box with 2 alpines and it slams???????? won't be disappointed!! [ Billy  Aug 23, 2015 ]

Hey thank you guys for your answers. I cant wait til my box come in now [ Josh  Mar 07, 2015 ]
Yes, just depends on the speakers ya got to what's passing them and how loud. [ JASPERW  Mar 06, 2015 ]
Ported boxes in general produce lower, due to less restrictions of the sub verses a sealed box, also the sub takes less power to sound good verses needing more power for sealed box. But you still need to properly match the sub to the enclosure also. Rule of thumb is to at least have a amp that will put out a minium of 3/4 of the subs RMS WATTS, it is better to over power a sub then to under power one, under powering a sub can possibly damage a sub. [ RICKY A  Mar 06, 2015 ]
Josh, great question. I bought this box last year and love it. It is fairly large, and the cubic space matches most sub requirements for a ported box. I currently run two JL w3v3 svc 12" subs, wired at two ohms with a jbl gto mono class D amp In my Jeep Wrangler Rubicon. It pounds with punch and with great lows. You can hear me coming from at least mile away in rural area. If you want people to hear coming from farther away, it's going to be the subs and amp that you choose, not so much the box. You just want to make sure the box (cubic space) meets your sub requirements for a ported setup. Hope this helps. Justin [ MATTHEW J  Mar 06, 2015 ]
It's all relevant to what subs and how many watts your running, this is definitely a great box and it made my subs hit hard and low. I would definitely recommend this box especially for the price. [ JACKSON  Mar 06, 2015 ]
Yes that's what you would have to do. Anymore questions let me know! [ HERSHELL B  Feb 12, 2015 ]

I have it in my 1999 BMW 528i, and it perfectly fits all the way to the back. Just go out with a tape measure and match the specs, give your self some play room for thought tho. [ CHRIS  Feb 11, 2014 ]
I would measure just to be safe. I bought one for my 2003 4Runner and it fits perfectly behind the seats with room for other stuff in the back. [ NOHE SEBASTIAN  Jan 15, 2014 ]
It will be snug [ BRIAN  Jan 15, 2014 ]
It's a pretty big/heavy box. Not too sure how big the trunk of an Altima is, but if you can make it fix you won't regret it. This box allows me to bump harder then any other dual 12" subs. I've even bumped harder then two 15" subs. This box is worth it. [ JOHN M  Jan 15, 2014 ]
There is plenty of room left but you need to measure your truck vs the box measurements. [ JOHN  Jan 15, 2014 ]
