Boss MC420B and MCBK420B the stereo system for motorcycles and scooters

MC420B-MCBK420B Boss Marine

Boss MC420B and MCBK420B stereo systems built specifically for the needs of small voyages, such as motorcycles, scooters, engines and ATVs.


The Boss MC420B and MCBK420B are complete stereo systems for motorcycles, scooters and other small vehicles such as ATVs.

They include a powerful 600 Watt amplifier (peak) with Bluetooth connectivity, so you can easily send any song from your smartphone and the system will make you listen to the music at the volume you want.

The two powerful speakers complete the system to perfection, making an unsuspected acoustic quality and embellishing the aesthetic lines of your bike. Speakers are quickly installed on any tubular.

The amplifier includes an AUX input and volume control.
The two models are distinguished only by their colour, the MC420B is chrome-plated, the MCBK420B is black.

Remember that the smartphone should not be used when driving and that the stereo system should not overwhelm the possible acoustic signals coming from the road.
