With all four speakers installed, you can hear the sound of the system, even if the bike is at 75 mph. Now when it comes to the installation, it doesn’t have any instructions included. The paper included with it has some instructions but showing only the wiring diagram, speaker wires, and volume control. However, the installation is not that difficult overall. You can search the internet for directions or look at the exact model of the unit on YouTube, and you can find plenty of instructions there. If you are not comfortable with that, then you can also call their customer support, and they will guide you on the proper installation of the system.

There is a bit of a challenge when it comes to attaching the clamps to close on the engine guard. You will need a pair of vise grips to close the clamp and install the screw and nut. You can also use foam to place between the clamps and the engine guard.

Don’t expect a good bass with this unit because like the majority of motorcycle speakers on the market today, they don’t have that decent bass. But if this is not an issue for you then these are good speakers with a lot of output.

It’s easy to pair with your smartphone wirelessly. You can also use the standard AUX ports if you prefer them. Its amplifier is also well made and does not heat up. But comparing the Bluetooth and AUX output, AUX provides clearer output sounds.

When it comes to battery consumption, it drains the battery even when not in use. It is not ideal, but most speaker systems available work this way. It is a common issue for most motorcycle speakers. So we can expect this to happen, so always keep that in mind.

Additional Information

  • The MCBK470B (speakers+amplifier) ​​is weatherproof or in other words, water-resistant. It is not waterproof. This setup can resist the penetration of water to some degree but not entirely.
  • The speaker leads are on the short side & hard-wired into the plug so you will have to cut and solder in a length of wire to get to the rear of the bike.
  • Depending on where you mount the amp you may have to modify the front leads as well. The fact that all wires are hard-wired into the main plug is the single drawback to the Boss systems.
  • It will work on any 12v system car, boat, motorcycle, slingshot, or scooter.
  • The MCBK470B is compatible with an FM radio provided the FM radio features an auxiliary output.
  • You may connect the MCBK470B directly to the vehicle’s battery, however, you must manually disconnect the MCBK470B after use to avoid draining your vehicle’s battery.

  • The MCBK470B does come with mounting hardware. The speaker includes mounting brackets adjustable to fit 0.75 “to 1.25” bars.
  • You cannot wire both left and right speakers together in series to reduce the amount of wire you need to run because the amp controls the amperage to each wire which controls the amperage to the speakers on that wire. So it would reduce the sound output dramatically.
  • The MCBK470B was designed to handle only four speakers, adding more will not only void the warranty but it will also cause the MCBK470B to perform poorly.
  • No external buttons or switches on the amp.
  • An on/off toggle switch could be wired in but unnecessary.
  • It comes with a standard fuse built inside the amplifier.
  • The MCBK470B unobstructed can have a solid Bluetooth signal at 30 feet away.

  • The MCBK470B does not have adjustable bass or an add-on subwoofer available.
  • The systems do not have RCA inputs available for this type of setup, but if you have a dual Bluetooth phone, it can be done.
  • The amplifier for this unit was designed for the speakers that it comes with.
  • These speakers and amps are made for a motorcycle but if you are handy with fabricating mounts and are savvy with wiring it is possible. However, you would more than likely have to get the extended wire as they aren’t that long.
  • This unit does not have fading options, you will need to place the speakers according to your personal needs.
  • The unit runs off 12 volts. If you don’t have anything that keeps the battery charged the battery will die after a few hours.

Our take on BOSS Audio Systems MCBK470B

This audio system is a great option among all the motorcycle speakers on the market. Looking at its specifications and users’ responses you can see that it deserves to be on that top list of choices. For big bikes that run frequently around 60 to 75 mph then you can still hear its sound and make people’s heads turn when you pass by. It depends if that might be comfortable for you or not. But who cares right? As long as you can hear your favorite music along with that revving engine sound.

Again the sound is good, however, do not expect much bass because it has almost no bass mostly, mid and high sounds. However, overall the sound is really good considering its price and size. You will all get the necessary features you need while riding.
