Overview

Our take on the Sound Ordnance™ Bass Bunker

Sound Ordnance's rugged Bass Bunker enclosures come built to last and ready to help your sub deliver real low-frequency firepower. These unloaded boxes feature high-grade, medium-density fiberboard construction, with sealed inner braces that help combat resonance by reducing vibrations. Rounded outside corners and recessed panels allow them to fit into more vehicles, while tough black carpeting defends against incoming nicks and scratches. Bass Bunkers make a great solution when building your own box is not an option.

Features

Materials: The Sound Ordnance BB12-125S Bass Bunker is an unloaded, hatchback-style sealed enclosure for one 12" subwoofer. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet.

Internal Box Volume: The enclosure has 1.27 cubic feet of airspace.

Terminals: The BB12-125S is equipped with a pair of spring-post speaker terminals 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 the terminal has an attached 21" length of speaker wire for connecting the subwoofer.

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

Customer Q&A

Crutchfield asked  
Why did you buy this?

A good sealed enclosure for all types of music from rock to rap music is always a good choice but if you only go for rap music a ported box or a band pass box is always best and the sub always looks cool behind the plexiglass. [ JAMES  Aug 09, 2018 ]

It was recommended to me by a support member. [ Cyndi  Dec 27, 2016 ]
Decided on a sealed box for tight accurate bass, as I am generally used to ported boxes. My taste in music varies when listening to SirusXM : BPM, Hair Nation, Octane, Lithium and the new Turbo channel. These are mostly guitar and kick drum heavy, with a need to hear vocals. I am probably missing out on the boom for the BPM music, but since i mostly listen to rock, I thought to try out a sealed box. I am trying out S/O for the first time. [ Vincent  Dec 04, 2016 ]
It was suggested to me by both Rex and Chuck (Crutchfield Advisors) [ Adam  Nov 16, 2016 ]
I've had Rockford Fosgate products before and been please with the quality every time. [ Anthony  Oct 03, 2016 ]
Loading it with a 12" sub. Sounds great! [ Michael  Aug 09, 2016 ]
Cant build my own box [ Chris  Jul 17, 2016 ]
solid [ JEFF  Mar 15, 2016 ]
It came with one bass package [ Alie  Feb 25, 2016 ]
Part of a package. Great reviews and clean specs. [ Kelly  Feb 09, 2016 ]
Needed an enclosure that matched the recommended sealed volume of my 12" subwoofer. This one seemed like a good choice. [ Joseph  Dec 31, 2015 ]
This went well with my Kicker 12" [ Liam  Dec 28, 2015 ]
Looks to be good construction and worth not having to build it myself. [ Rhett  Dec 14, 2015 ]

6 questions already asked

That subwoofer sure will fit into this box! I'd recommend adding around a quarter pound of polyester box stuffing inside it to get the box to work like it has the perfect sealed box volume. Here is this box stuffing: www.crutchfield.com/p_027808/item.html My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101 [ Paul  Aug 10, 2018 ]  Staff
Yes you can modify almost anything but I would recommend a purchase of a specific application. Why try to experiment and play with the unknown. Crutchfeild has a large assortment of boxes to chose from. I would ask one of thier experts. [ Mike  Jul 13, 2018 ]
It is on the straight vertical side. [ Steven  Nov 17, 2017 ]
Hole on slanted side [ GARY  Nov 17, 2017 ]
This box will not suit an Alpine SWR-12D2, the cut out diameter for the sub is 10-7/8th while the enclosure has a diameter of 11-1/16th as well the optimal space for the sun is 0.75 cubic feet maxing at 1 cubic feet, this enclosure has 1.27 cubic feet. A perfect pair would be a Rockford Fosgate P3-D2. [ Chris  Oct 22, 2017 ]
I have no clue. Try calling Crutchfield tech line. I loaded mine with a focal sub. [ JUVAN  Oct 22, 2017 ]
I would not recommend it. That box is really far away from the recommended specifications for the subwoofer that while it would play, it will not play like it should. This box will work a lot better with the Rockford Fosgate subwoofer: http://www.crutchfield.com/p_777BB1220V/item.html Feel free to call an advisor on 1-800-324-9695 for a personal recommendation.
