Bass Slammer unloaded, vehicle-specific enclosures are inspired by the same technology incorporated in MTX ThunderForm enclosures. Bass Slammer enclosures are available for many of the hottest-selling vehicles on the market and are made of a high-density polyethylene resin to ensure that you don’t get any of the “ping” common in fiberglass enclosures. The resin is color-matched to the interior color options available for each vehicle.

Bass Slammer enclosures are tough as nails. They are made using rotational molding. Unlike injection molding, Bass Slammer enclosures come out of the mold with no seams, so you don’t lose any of the sonic quality of the subwoofer.

Bass Slammer enclosures are also internally braced to eliminate flexing and warping so you get the tight bass you’re looking for.

Enclosure Specifications

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.
Sealed
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
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
Height
The height of the item, measured from top to bottom, in inches.
14-3/4"
Width
The width of the item from left to right (side-to-side) measured in inches.
25-1/8"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
6"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
1
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 posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
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.
Paint
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.

Type of Enclosure
Some of our Vehicle Specific enclosures are loaded with a subwoofer and an amplifier, some are only loaded with a subwoofer, while some are empty boxes.

MTX unloaded

June 20, 2014

The MTX box fits great in my 98 Ford expedition but unfortunately you can't just put any 10 inch sub in it. Most 10 inch subs are actually 11 inches and the MTX is the only true 10 I have found. I had to modify the box to fit an 8 inch sub so it would fit. I recommend that you purchase the loaded MTX so you can save the trouble. Also, before you put the truck back together check the factory speaker wire connection first mine were not connected.

Best Answer: Hello Jorge,

Unfortunately, we do not Fabricate enclosures at this time. In addition, neither MTX or any other manufacture (that we carry) has a solution for your vehicle.
