    Installation instructions and specifications for the Channel Vision OS526 — a 5.25" marine/outdoor speaker built for weather-resistant, all-condition use.

    Overview

    The OS526's case is weather resistant and made with UV-stabilized ABS. For longest life, Channel Vision recommends placement in a protected area, such as under an eave, even though the speaker is rated for direct outdoor use.

    Features

    • Weather resistant design
    • Aluminum grilles and brackets
    • Stainless steel hardware
    • UV protected cabinet resists sun fade
    • 14 AWG gold-plated terminal posts
    • 5.25" long-extrusion woofer
    • 0.5" high compliance polymer tweeter
    • 18dB/octave crossover network
    • Tweeter protected by poly switch

    Installation

    • The OS526 may be mounted vertically or horizontally.
    • To set the OS526 on a shelf, attach the included rubber feet.
    • Wire with AWG 16 or larger, stranded wire.
    • For proper phasing, both speakers must be wired alike — connect red wire to red terminal on speakers and to red or plus terminal on amplifier.
    • To control the volume locally, use an impedance-matching volume control such as the Channel Vision VC-302.
