Features

Design: The SB112 is an unloaded, sealed enclosure for a single 12" subwoofer. It's constructed of ¾" MDF (medium-density fiberboard) and covered in charcoal colored carpet.

Internal Box Volume: The enclosure has a volume of 1.2 ft³.

Terminals: The wire terminals are spring-posts (one pair), mounted on the left side. 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 subwoofer.

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

Customer Q&A

3 questions already asked

Q
Would a Rockford Fosgate p3 dual voice coil work in this box or would it be better to get a box for two 12-in subs and pair it with my JL 12-in dub one?

Greetings Andrew. This SPL box is a recommended box for the Rockford Fosgate P3 12 inch. Not sure if I would mix different brand subwoofers. The W1 is rated for 300 watts, the P3 can take 600, or a minimum of 300. The W1 can work in a similar cubic feet of air space, so you could uses one and one with an amp that does 600, and can get the subwoofers impedance to match that.

Q
Will my Memphis SRXS1240 12 inch fit in this box?

While your subwoofer can fit into this box, the internal airspace is not ideal for it and this subwoofer box is a better match: www.crutchfield.com/p_777BB1295S/item.html

Q
Will it fit under my back seat in my f150?

So, with subwoofer boxes that are not vehicle specific, you may have to take some measurements of the available space where you wish to mount the enclosure to check fitment. This enclosure has the dimensions of 16.25"W x 13.125"H x 12.75"D.
