The Boss Audio MCBK425BA is a 3 inch Bluetooth speaker system made for motorcycles, scooters and ATVs. Boss rates it at 600 watts maximum from a built-in Class D amplifier. It streams music over Bluetooth or plays from an MP3 player through the aux jack.
The speakers are rugged and all-weather, measuring 3 x 1.5 x 3.5 inches each. A wired remote handles volume and other controls. Frequency response is 20 Hz to 20 kHz, sensitivity is 75 dB, and it runs on 12 volts DC.
Because it’s a compact 12 volt system, it can also work on a small boat, jon boat or golf cart where space is tight. It comes as a pair with mounting hardware and a manual. Confirm the intended application and fit before installation, especially when nearby models in the same family look nearly identical. Browse more marine speakers.
