Product Type
Vehicle-specific loaded sub box,
Price Range
Number of Subwoofers
This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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.
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend giving your subwoofer(s) 75% - 90% of the recommended RMS rating.

Promotions we have offer More Ways to Shop for items that are on clearance, last chance, special offer and sales, Made in America, and more!
Final Wired Impedance
This is the final impedance of the system as the amplifier will see it. If the final impedance is for two sets, it means that the enclosure has two sets of terminals at the listed impedance.
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.
