    I had been looking for a box to meet the manufacturer recommended air space for Alpine Type R 12’s. These fit the bill perfectly. Alpine suggests having 1.25 – 1.5 Cu ft per chamber, and these come in at 1.44.

    Having the right box for your subs makes all the difference in sound quality and performance.
    The build quality on this box is great. Built with good materials, carpet matches most trunks, and the terminals are also great quality.

    The terminals accept 10 gauge wire, so if you are running 8 gauge, you will need to trim a bit off.

    The connections inside the box work best with sleeve terminals, but you may also use spade terminals and connect to the bolt below the sleeve prongs.
