BOSS MC470B Review

For motorcycles with a pre-installed audio system, there are times that we are not satisfied with its output. All you need is the new audio system to give more satisfaction to your experience for the length of time you stay on the road.

With the Boss MC470B, you can listen to your favorite music while you are on the road with your bike. Though there is a certain limit to how much you can hear the sound of your audio system especially when you are at a higher speed.

In this review, we will first look at its specifications which are the official release of the manufacturer. Next, we will give my honest opinion. Then we will provide some additional information to answer some questions you have or to cover the broader topic regarding this scooter.


On a freeway, surprisingly, this speaker system is still audible even at 80 mph even without a windshield. Although there are still other users who say that it is not that loud and audible around 50 to 70 mph. However, the majority of them still hear the sounds even if they are using a loud bike. Now imagine adding a windshield?

Its sound quality is clear, but it doesn’t have bass but, not much of a big deal. For the cost of that much power and four speakers, it is a workable trade-off. That revving sound of the engine will serve as a bass-like remix. Interesting right?

But it’s just unexpected that it doesn’t have an on/off switch on the amplifier. Wouldn’t it be better to have an essential button on the amplifier? However, its volume switch is good and protected in any weather.

When it comes to overheating, the amplifier has no problem with it. Touch it, and you will feel cool to warm at max.

The Bluetooth connects every time, as soon as you flip the toggle switch to ON, and the pairing is fast and very easy.

The initial installation, primarily the clamps on the speakers take a long time and a certain amount of patience to get right. The clamp is not better than others. It is cheap and easy to bend. A 2-piece clamp that has a slot and tab that connects the backside of the clamp while using the mounting stud on the speaker for the front side of it (or vice-versa, depending on how you mount the speakers). We suggest that you add foam pipe insulation as a spacer and protect these chrome speakers from metal on metal.

Now let us talk about the amp’s power and watts. This is our subject opinion, however doing the math comparing it to other D amplifier readings, you will find out that when it is at full volume it beats between 1.8 and 2 A roughly 13 V DC or 23 to 26 watts. There are other D amplifier speakers on the market running 500 watts and 2 ohms and 300 W, and four ohms pull in the range of 25 A. The boss audio MC470B system is 8 ohms running 16 gauge wire and was pulling a maximum of 2 amps during my test.

There is also another issue about the sound that sometimes gets cut off when at the half volume due to insufficient supply of power. And one of the annoying things to some about this audio system is the beep sound, but to some, no big deal.
