2020 BMW K1600B Four Speaker Arc Audio Upgrade

Mike Bartells
A client from Raleigh recently contacted the Motorrad Audio team to inquire about upgrading the stereo system on his 2020 BMW K1600B motorcycle. As with Harley-Davidson touring bikes, the stereo system on these BMWs doesn’t play loud enough and isn’t very clear at higher volumes. Because of the small speakers BMW uses, the system also sounds weak and thin with no bass. After talking to the client about his listening preferences, we proposed an amplifier and speaker upgrade that uses the Motorrad Audio front fairing pods and saddlebag speaker panels. With a plan in place, the client brought his bike to our sister company, Extreme Audio, in Mechanicsville to perform the installation.

The project started with removing the tiny 3½-inch speakers in the front fairing to make way for a set of our Motorrad Audio 6½-inch speaker pods for 2021 and older BMW K1600 touring motorcycles. These pods are designed and manufactured right here in the U.S. and can withstand the harsh conditions that motorcycles encounter. The client chose ARC Audio Moto CX6 speakers for this upgrade, based on their reputation for balanced midbass output and precise midrange performance.

This particular K1600 doesn’t have any rear speakers. The client chose our 6½-inch rear speaker upgrade panels for BMW K1600 saddlebags to ensure that the system would play loudly enough. The Extreme Audio technicians modified the rear bags’ top portion to allow these custom speaker mounting solutions to fit perfectly. Crucially, the design of the speaker panels doesn’t interfere with or modify the operation of the locking/latching mechanism, so the owner’s belongings will remain safe and secure. The client chose ARC Audio CX6 speakers for the rear application.

ARC Audio Amplifier Delivers Efficient Power

The upgrade on this BMW K1600B features a four-channel ARC Audio Moto 720 amplifier. The amplifier is installed on the rear wall of the right-side saddlebag using weather-resistant glands to route wiring to the battery, speakers and source unit. As you can see from the images, Extreme Audio wrapped all the wiring in automotive-grade PET harness tape to protect it from damage.

This four-channel amp is rated to produce up to 150 watts of power from each channel. While this is one of the best-sounding motorcycle amplifiers on the market, the amplifier’s efficiency is a feature that’s even more important for an application like this. This amp runs cooler and draws less current per watt than any other we’ve encountered. The result is an audio system that can play louder without taxing the limited electrical system on a motorcycle like this BMW.

Extreme Audio finished the project by setting the crossovers and level controls on the amplifier to ensure that it would deliver a clean signal, even at high volume levels. The client was thrilled with the upgrade and blown away by the improvement in impact and clarity.
