Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Subwoofer Cutout Shape
This is the shape of the enclosures cutout hole and defines the style of subwoofer that can be installed.
Round / Circle
Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Vehicle Specific
Cutout Diameter or Length
The actual diameter of the hole in the subwoofer box. Length is the measured length per side of a square subwoofer or speaker opening.
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
1.6 cubic feet
Box Volume (Each Chamber)
This is the total air space inside each chamber of the empty subwoofer enclosure. By matching this value with the recommended air space of the subwoofer, you will be able to know if the subwoofer will match this box.
0.8 cubic feet
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Spring clips
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.
Compatible Vehicle Make and Model
The model of vehicle that this vehicle specific product is designed for. Please keep in mind that engine variations can affect the compatibility of the products.
Chevy Silverado
GMC Sierra

Good value, needs a bit of work tho

March 9, 2017

Best priced box around,best price for box on sonic electronic, much lower than anywhere else. Was boxed nicely and delivered undamaged. Professional carpeting, fit great in my 2011 Silverado 1500 ext cab. Used with older dual kicker cvr 10"'s with a 600watt amp. The kickers barely fit height wise but fit none the less after dragging them in the last 1/4 to 1/8" after they met a small amount of resistance(rubber plastic bumpers on magnet body of these speakers). Box hits pretty hard for the Sq footage it is, but Definently had air leaks. With seat down I don't really notice them so I left as is. Bedlinered box would be sealed if thats your thing, spend a few more $$. Fyi you will need a drill to install side boards into main box and there is no where to put your amp, I ran mine on top of the box for now, just barely fits under seat when down. May move to rear seat center footwell on trans tunnel and just tell people to watch their feet!

The box fits perfect under the back seat of the extended cab and for the money for a sealed double 10" box is good deal and sounds great with the down firing position I have two Rockford 10's and sounds great in my 2011 GMC Sierra ext cab.

Great value!! Great sound!!

January 13, 2017

I was very pleased with this enclosure. I install custom sound systems for a living and i am a mechanical engineer by degree. There is actually an impressive amount of air space within the enclosure. I have 2 10's running off of a 1200 watt RMS JBL amplifier. The only real negatives is that one woofer cut out was a tad too small and i had to sand it down, and air leaks out of the speaker terminals so they need to be siliconed from the inside.

!!! One thing to note: on my 2007 Chevy NBS extended cab has less floor space in the driver's side, so during high excursion the woofer makes partial contact with the floor.

!!! In order to mount the massive amplifier on top of the box, i used high strength washers to elevate the rear seat about an extra inch. This allowed the seat to be folded down properly.

Good luck!!

Can I put two JL 10w3v3-2 subs in these?
A shopper on Oct 13, 2014
Best Answer: Hello,

Yes. Being a pre-fab enclosure, be prepared for the possibility of needing to shave excess from the opening of the enclosure.

Will my two 10 inch alpine type r 5th gen fit in this box?

· Add Answer · I Have This Question Too (3)
In one of the pictures, it looks like the two separate speaker enclosures are different depths. Is that so? That could effect the woofer that I choose. Additionally, I entered in my vehicle information(2008 Silverado 1500 CrewCab) and It gave me this extended version product. Does that mean it is compatible with a crew cab?
mikey on Mar 26, 2017
Best Answer: It is not compatible with the crew cab without modification. I bought it for the crew and had to extend the feet to get it to reach the floor on both sides.

I have a 2009 GMC Sierra extended cab will this enclosure fit with no issues? Also what speakers that you sell are recommended for this enclosure?
Tim D on Feb 3, 2015
Best Answer: Hello Tim,

Being an enclosure specifically meant for a 07-Up GMC Sierra Extended Cab , its intended to fit well with no issues. We aren't sure what your concerns are, unfortunately, so feel free to contact the manufacture for details, or forward more details to our Sales Team, info further below.

In regards to the subwoofers that fit the enclosure, we aren't going to make any suggestions, because we don't know your application, preferences, or budget. However, If it were up to us, we would go with a pair of JL Audio 10TW3-D4 all day. The are , hands down, our installers #1 choice.

Also, please note, these threads are meant for product questions, and are submitted to customers that have the product. Obviously those customers cannot answer questions related to what they "sell"; So please submit such an inquiry to [email protected] or call our Sales Team at 1-877-289-7664 opt 1 . Otherwise you will likely get confused replies from various customers. That is always fun =] .

What is the mounting depth?
A shopper on Nov 15, 2015
Best Answer: the general features says 6.25". I mounted a pair of Kicker comp 10". I had to cut a about 1/8" of wood/carpet around the mounting holes. Subwooferr diameter was too large just but 1/8 inch. You may have the same problem with other subwoofers?
