  • Our take on the RTB65A

    The Rockville RTB65A is a powered bass tube for car audio: a cylindrical subwoofer enclosure with a built-in amplifier, so it needs power and a signal rather than a separate amp. Bass tubes are valued for punchy, deep low end in a compact footprint that fits trunks and hatchbacks more easily than a big box. It suits drivers who want to add bass to a factory or basic aftermarket system without building a custom enclosure. Against box subwoofers it trades some output and tuning flexibility for simpler install and smaller space.

    Pros
    • Built-in amplifier means no separate amp to buy or mount
    • Cylindrical tube shape fits tight trunk and hatch spaces
    • Adds punchy, deep bass to a basic system
    • Simpler wiring than a separate sub and amp combo
    Cons
    • Tube shape limits placement options compared with a box
    • Built-in amp leaves less room to upgrade power later
    • Bass output and tuning depend heavily on the install
    • Not a substitute for a properly tuned multi-sub system

    About the RTB65A

    The Rockville RTB65A is a powered subwoofer tube for car audio. It combines a 6.5-inch high-power woofer, a built-in amplifier and a vented tubular enclosure in one unit. The amp, subwoofer and enclosure are matched to work together.

    The cylindrical enclosure focuses bass pressure from the woofer face and the tuned rear aero port. A molded steel grill protects the woofer, and the tube is covered in aviation grade tweed with an embroidered logo.

    No custom enclosure building or amp wiring is needed. Connect power, ground and remote, then send a signal to the tube. It comes with four steel mounting brackets and two canvas straps with Velcro fasteners to hold it in place without permanent installation.

    Questions and answers

    Does the RTB65A need a separate amplifier?
    No. It is a powered tube, so the amplifier is built into the enclosure. You run power, ground and a signal to it.
    Will it fit in a small trunk?
    The tube shape is easier to fit into tight trunks and hatch areas than a large box. Measure your space before buying, since the cylinder still needs clearance for its diameter and length.
    How does it connect to a factory stereo?
    It takes a line-level or speaker-level signal depending on the inputs on the unit. With a factory head unit you typically use a line output converter or speaker-level input.
    Is a bass tube as good as a box subwoofer?
    A tube gives punchy bass in a compact shape and is easier to install. A well-built box sub usually plays louder and deeper, and gives more tuning options.
    What comes in the box?
    The powered tube itself with its built-in amplifier. Check the listing for included wiring, mounting hardware and the manual before you plan the install.
