2025 Road Glide Fairing Audio, Amplifier & 6x9 Cut-In Lid Installation
This 2025 Harley-Davidson Road Glide received a complete Garage Bagger Stereo audio installation with Cicada Audio fairing speakers and ring-radiator horns, a DS18 four-channel amplifier, a Cerwin-Vega 6x9 cut-in saddlebag lid kit, rear-output wiring, and complete system setup.
The install covers the details that determine whether a motorcycle audio system is simply installed or installed correctly: speaker preparation, saddlebag cutting, wire routing, crimping, heat shrink, battery connections, amplifier setup, voltage verification, reassembly, and final checks.

Late-model Harley-Davidson Road Glide audio systems require more than selecting powerful speakers and an amplifier. The fairing, saddlebag lids, signal path, rear-speaker wiring, amplifier installation, electrical connections, and final gain structure all have to be planned as one system.
This build adds front fairing output and rear saddlebag coverage while keeping the installation organized, protected, serviceable, and ready for real-world motorcycle use.

Complete 2025 Harley Road Glide Audio System
This Road Glide was upgraded as a front-and-rear motorcycle audio system rather than treating the fairing and saddlebags as separate installations.
The fairing uses Cicada Audio CM65X mid-bass speakers with RR075T ring-radiator horns mounted through Cicada's Road Glide-specific grilles. The rear stage adds Cerwin-Vega 6x9 speakers through a cut-in saddlebag lid kit, while the DS18 ION1600.4D provides the four-channel amplification required to drive the system.
Installation approach: Every speaker location, wire path, amplifier connection, and crossover/output setting was treated as part of the complete motorcycle audio system.
Cicada Audio Fairing Speaker Upgrade
The Road Glide fairing received Cicada Audio CM65X 6.5-inch mid-bass component speakers. These drivers provide the mid-bass foundation for the front stage and are paired with Cicada RR075T ring-radiator horn speakers for the upper-frequency output required in an open-air motorcycle environment.
Cicada Audio 24CHDRGGT-075 Road Glide grilles provide dedicated mounting locations for the RR075T horns, allowing the front speaker and horn package to integrate cleanly into the late-model Road Glide fairing.
CM65X Mid-Bass
The 6.5-inch mid-bass drivers create the body and impact of the front stage while working with the separate horn section above them.
RR075T Horns
The ring-radiator horns add efficient high-frequency output and projection for riding conditions where road, wind, and exhaust noise compete with the audio system.
Cutting the Saddlebag Lids for 6x9 Speakers
The rear stage uses a Cerwin-Vega 23.5+ Harley-Davidson 6x9 cut-in lid kit. A cut-in system allows the existing saddlebag lids to be modified for speakers instead of replacing the complete lid assembly.
The process shown in the video includes positioning the template, marking the speaker location, cutting the lid opening, preparing the mounting area, laying out the screw holes, and installing the finished speaker assembly.
Cut once: Speaker placement and template alignment need to be confirmed before cutting. The lid shape, hardware, internal clearance, and final speaker orientation all have to be checked first.
Rear Audio Wiring and Cicada 24HDRO Harness
Adding speakers to the saddlebags requires a clean and protected signal path from the motorcycle to the rear speaker locations. This build uses the Cicada Audio 24HDRO rear-output speaker wire harness as part of the late-model Harley rear speaker integration.
Wire routing has to account for bag removal, moving parts, heat, abrasion, water exposure, serviceability, and the location of the speaker connections inside the saddlebags.
The video shows the harness and connection preparation along with the routing and protection work needed before final reassembly.
DS18 ION1600.4D Four-Channel Amplifier
The system uses a DS18 ION1600.4D four-channel amplifier to provide dedicated amplification for the upgraded front and rear speaker stages.
A motorcycle amplifier installation has to balance output capability with available mounting space, airflow, power wiring, grounding, speaker impedance, input signal level, and service access.
In this installation, the amplifier is only one part of the job. The final result depends on the wiring, connection quality, setup, output verification, and speaker configuration surrounding it.
Battery Connections, Crimping & Heat Shrink
High-output motorcycle audio requires reliable electrical connections. The video shows the battery connection process along with terminal preparation, crimping, ring-terminal installation, and heat-shrink protection.
These details matter because the amplifier can only perform as well as the power and ground connections feeding it. Loose terminals, poor crimps, unprotected wire, or incorrect routing can create voltage loss, heat, intermittent operation, or long-term reliability problems.
Clean Crimp Connections
Properly prepared terminals create a mechanically secure electrical connection before the connection is protected and routed.
Heat-Shrink Protection
Heat shrink helps protect completed connections from abrasion and environmental exposure while giving the wiring a clean finished appearance.
Amplifier Setup and Output Voltage Verification
After the physical installation is complete, the amplifier still has to be set up correctly for the speakers and signal feeding it. The video includes amplifier setup notes and output-voltage checking on the installed channels.
Voltage verification provides a repeatable way to confirm amplifier output during setup instead of relying only on the position of a gain control.
This particular build does not use an external DSP, so amplifier crossover and level setup become especially important to controlling the speakers and balancing the front and rear stages.
Final setup matters: Installing high-output speakers and an amplifier without correctly setting gains, filters, and output levels leaves a significant part of the system unfinished.
Final Reassembly and Installation Check
Once the speaker locations, wiring, amplifier connections, and electrical setup were completed, the motorcycle was reassembled and the installation was checked before delivery.
Final inspection includes confirming secure wiring, correct speaker operation, clean saddlebag and fairing assembly, protected connections, and a system that is ready for normal road use.
