A client from Richmond recently visited Extreme Audio to ask about upgrading the sound system on his 2024 Harley-Davidson Road Glide. As happens frequently, the client wanted the stereo to be clearer, louder, and deliver more bass output. Improving bass performance isn’t easy on a motorcycle, but our fabrication team had a plan to give this client what he wanted.
Harley-Davidson Bass Upgrade
We started by scanning the interior of the saddlebags to create a 3D model. Then, we designed an adapter ring that would allow a 6×9 speaker to be installed and seal perfectly against the inner wall. After 3D printing the adapters, we added a foam gasket to ensure a perfect seal. We also developed 8″ Mid-Bass rings for future installations!
We should mention that these aren’t just any 6×9 speakers—they are Diamond Audio MS69CX CoaxSub drivers. Diamond has optimized the performance of the woofer in this two-way speaker to produce significantly more bass than a typical 6×9 speaker. We finished the bass upgrade by adding a layer of water-resistant Frogzskin mesh over the holes to keep water out of the saddlebag.
When custom lids are available for these new compact saddlebags, the client plans to return to have us add a second set of 6×9 speakers.
Motorcycle Speaker, DSP and Amplifier Upgrade
The next step was to upgrade the speakers in the front fairing pods. The client chose a set of Cicada Audio CH65.2v2 coaxial horn speakers. These super-efficient drivers will ensure every note is reproduced clearly.
The system is powered by a Cicada Audio CX150.4 amplifier. This is one of the few amps that fits into the fairing without modifications to the bike. Finally, we added an ARC Audio PSM-Pro DSP to handle integration with the factory source unit and allow our team to fine-tune the output of each speaker on the bike.
