Overview

Our take on the Sound Ordnance™ B-24

Sound Ordnance designed the B-24 dual bandpass subwoofer to be the bass fortress in your vehicle's sound system. The sturdy enclosure houses a pair of 12" polypropylene woofers in individual airtight sealed chambers, plus a third chamber that features a generous slot port for massive air movement. The enclosure's bandpass design increases speaker efficiency dramatically for impressive bass firepower. Best of all, you can watch the woofers swing into action behind the clear acrylic front windows.

Features

Materials: The Sound Ordnance B-24 is a pre-loaded bandpass-style enclosure with dual 12" subwoofers. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet. It also features dual clear acrylic front windows for viewing the subwoofers. The subwoofers feature polypropylene cones with rubber surrounds, 2" voice coils, and a heavy-gauge stamped steel basket.

Box Design: The enclosure has two separate sealed chambers in front of each subwoofer, and a vented chamber behind both subwoofers. The front-firing slot port is 2-13/16" wide and 13-1/2" high, and is centered between the speakers. The box has a total of 2.9 cubic feet of airspace.

Terminals: The B-24 is equipped with a single set of spring-post speaker terminals, mounted in the rear panel. The spring terminals will accept bare wire, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure, the two drivers are wired together to present a 4-ohm load to the speaker terminals.

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

Specifications:

  • Frequency Response: 42-165 Hz
  • Power Handling: Up to 500 watts RMS, 1000 watts peak
  • Sensitivity: 91dB

    • Width: 29.8125"
    • Height: 15.125"
    • Depth (bottom): 18.25"

Video: Sound Ordnance Subwoofers

Car audio systems need a subwoofer to fill out the bass in your music and give it a full-bodied sound. Watch this short Crutchfield video to learn about the subwoofer

Wow! Can this box rock!

Written by Jude, Director, Digital Imaging, on 7/10/2014 9:27:00 AM
My son just purchased a newer car, a 2002 Pontiac Sunfire and the sound system it came with was, well, awful. We sat down together and planned a system and since he was on a budget we decided we would go with our house brand Sound Ordnance for most of it, and we are not disappointed. We installed the P65-C in the rear deck using the SA69 6X9 adapter. We then installed the P-40 in the front doors with fabricated brackets we made from the 12x12 sheet of ABS #1208900903 and then used the Dynamat #15410415 to seal it all up and add sound deadening to the doors. We chose the JVC KD-R950BT for the Bluetooth and the generous power the internal amplifier has, plus the abundant color choices made it easy to match the red backlighting in the Pontiac. We needed bass so we used the Sound Ordnance B-24 and the Rockford Fosgate #575P500X1B we had from his previous vehicle and connected it using the EFX 8 gauge wiring kit #142PA8. We spent a Sunday working on this project and have to say it exceeded my expectations on sound. It sounds clear, the bass hits as hard as you want and the total price was well within his budget. This is a great system and it was also a great day spent with my son.

I don't quite remember the dimensions but it fit in my 2012 HHR no problem. The dimensions should still be listed in the description, when in doubt contact crutchfield support. They always answer my questions [ Brandon  May 06, 2017 ]
Thanks for your question. For information on selecting the best amp/sub combo 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. [ Kenny  Apr 19, 2017 ]  Staff

The two 12" drivers are already wired together inside the box to present a 4-ohm load to your amplifier. There wouldn't be any way to wire the Sound Ordnance B-24 at a 2-ohm load. I hope that helps! My bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159 [ Larry  Sep 12, 2016 ]  Staff
Thanks for your question. The dimension are: 29-13/16"W x 15-1/8"H x 18-1/4"D1 x 10"D2. This information is listed on the product page under "Product Highlights". Hope that helps. [ Kenny  Aug 09, 2016 ]  Staff
Sorry, no. This enclosure is pre-loaded, pre-wired &, pre-packaged. It cannot be re-wired prior to shipment. You can order 12" component subwoofers and a separate enclosure so that you can wire them as needed. 12" woofers: http://www.crutchfield.com/g_446450/12-Inch-Subwoofers.html?tp=68897#&clearAll 12" Enclosures: http://www.crutchfield.com/g_178650/Empty-Subwoofer-Boxes.html?tp=61651#&nvpair=FFSpeaker_Size|12%22 I hope that helps!

As long as the cut out diameter is the same, it should be fine. Although some speakers are not recommended for band pass enclosures, I have had many band pass boxes over the years and have had no issues. [ Thaddeus Holdren  Mar 28, 2016 ]
yes they will fit in box [ james  Mar 28, 2016 ]
You can fit it inside of the box but maybe the sound won't be the best, because the specifications of both subwoofers are different [ SPC CARTAGENA  Mar 28, 2016 ]
Yeah I purchased the m-1500 and the b-24's and they run perfect together it's been about 3 or 4 years and I push them hard and they sound great still to this day! It's hard to push the b-24's and get distortion from them. I would recommend! [ AARON  Dec 10, 2015 ]
Any amplifier is fine. The B-24 max is 500w RMS @ 4ohms. The M-1500 amplifier is 300w RMS @ 4 ohms. I'm currently running it at 300w RMS @ 4 ohms with an Alpine M500 amplifier. [ ALEX  Dec 03, 2015 ]
Yes it make the b-24 work and sound great . I have them in my 1984 Lincoln, Alpine head with XM radio a great match!! [ JERROME  Dec 03, 2015 ]
These subs do not need a bunch of power. I bought this box and a Sound Ordnance 4 channel amp and bridged it. Ran the gain at a quarter turn and they thumped. You will not hear distortion as easily with a band pass box, like you do in a conventional box. Everyone believes you have to run a lot of power to get great bass these days, you do not. [ Thaddeus Holdren  Mar 28, 2016 ]
I didn't have an amp for my speakers but I ran the subs just fine with a 600W amp by itself [ COLE  Oct 13, 2015 ]
I used a 5 channel amp. http://www.crutchfield.com/S-ByDOfNvPk0B/g_347150/5-channel-Amplifiers.html [ JASON  Oct 13, 2015 ]

This bass package is rated for 500 Watts RMS so it's not the subs you would have to worry about blowing, it's burning up that amplifier. I would not recommend installing Subwoofers into a vehicle without a bass knob (remote bass control usually near dashboard) or an after market deck in which you can control and change subwoofer settings. However if neither of those two applications are viable, here's how to tune your subs. Turn your stock audio to as loud as you would ever listen to it. That way you can adjust your subs to match these levels. Now to access your equalizing knobs. The low pass filter usually labeled LPS should be ALL THE WAY DOWN. The gain should be all the way down unless there is fewer than 500 Watts being used. If you're already at your 500 mark, leave it alone. And the bass boost knob can be used for that bump you want to have in your vehicle. This is tricky because you want to get it is close to peaking your subs as healthily possible. Remember you already turned your audio to as loud as you would ever listen to it so keep that in mind during use, so as not to blow your subs. Hope this helps! [ BRIAN Z  Dec 22, 2014 ]
You adjust the sound to your preference. There is no specific setting that they should be at, all you need to do is listen and turn until you find what you like. [ TANNER  Dec 21, 2014 ]
Its all about feel and preference. You will just have to play with it until you find what works for you. [ JASON  Dec 21, 2014 ]
It seems that these subs can handle way more than noted...I would turn the gain up and let it fly....im running them off of a arc audio 700 watt amp at 4ohms and they seem like they can take way more... [ ANTONIO  Dec 21, 2014 ]
The best way to learn is go to YouTube and search "tuning subwoofer amplifier" you should get some helpful videos. [ ALEX  Dec 21, 2014 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Nov 22, 2014 ]  Staff

My amp is 4 channel and works fine with the single terminal [ THOMAS  Mar 24, 2014 ]
Greetings! The box only has (1) terminal for both subs. The box is wired for 4 ohms. I'm using a Arc audio 300x2 briged@4 ohms and it sounds amazing.... Can't beat this set up for the money. [ ANTONIO  Mar 24, 2014 ]
This is a Band-Pass enclosure in which both subs are connected to a single + - terminal. The Amplifier i've equipped mine with is the Sound Ordnance M2250 and its a 4 channel bridged to 500 watts RMS. I couldnt be more satisfied with my equipment and by the way it looks and the price is amazing. These subs sound phenomenal in my BMW 3 series. [ BRIAN Z  Mar 24, 2014 ]
Only has one terminal for both subs, you cannot bridge it with a four channel amp u need both terminals having said that I have has this product for the past 4 years, I have had no proublems out of the subs sound great for what I'm looking for out of subs, dependable and crutch field customer service and warranty can't be beat [ BRAYDEN L  Mar 24, 2014 ]
