About the SPL Boxes SB210

Bob Bihlmayer

We all know how a good subwoofer can enhance your musical enjoyment, but not everyone wants to build their own box. SPL Boxes to the rescue! These heavy-duty enclosures can take the punishment of the car environment, with rugged 3/4" MDF construction to give your sub plenty of support. Attractive and tough charcoal carpet protects the box from nicks and dings, while gold-tipped spring terminals hold your speaker wires securely. This SB210 box holds two 10" subs in a sealed enclosure.

Product Research


Design: The SB210 is an unloaded, sealed enclosure for two 10" subwoofers. It's constructed of ¾" MDF (medium-density fiberboard) and covered in charcoal colored carpet.

Internal Box Volume: The enclosure has two separate chambers, each with a volume of 1.0 ft³.

Terminals: The wire terminals are spring-posts, two pair; one pair mounted on each side of the enclosure. The spring terminals will accept pin connectors and bare wire up to 12-gauge. Inside the enclosure there are 0.205" male quick-slides (will accept 0.205" female quick slides) for both the positive and negative terminals. The wire can also be attached using the nuts holding the quick-slides in place.

Note: Speaker wire is needed to connect the terminals to the subwoofers.

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

does this box fit under a toyota tundra double cab back seats?

Without knowing the year of your Tundra I can't say for sure that it will or won't fit under the back seats. According to our research on several Tundra's, the maximum height is around 6" or less under the seat. The dimensions of this box are 28.375"W x 13.25"H x 13"D. If you'd like to give us a call at 1-800-324-9695 we would be happy to look into a vehicle specific enclsoure for your Tundra!
