BOSS Audio Systems MC900B Amplifier 4-Channel, Weatherproof, Bluetooth Remote

Product Description

The MC900B is a 4-channel car amplifier designed to run without a separate head unit—power up the unit and connect speakers. It delivers up to 500 high-output watts total at 4 ohms, with 94 watts RMS per channel when driven at 4 ohms. Bluetooth connectivity is included via a remote control, allowing wireless music streaming from devices and supported apps such as Spotify and Pandora. The chassis is described as weatherproof for light exposure, making it suitable for use on ATVs and boats where exposure to the elements might occur. It supports full-range operation, meaning you can power conventional speakers as well as subwoofers, and it provides RCA outputs for connecting other audio equipment. The unit is designed for 2/4 ohm impedance configurations, broadening compatibility with various speaker setups. In short, it combines power, wireless control, and versatile speaker compatibility in a single marine/ATV-friendly amplifier.
