Cicada 4-Channel Amplifier & 4 CXX Coaxial Speakers — 2024+ Street Glide Audio System

Want strong, balanced sound across the entire bike — not just louder fairing speakers?

On 2024+ Street Glide models, wind noise, helmet turbulence and factory system limits quickly overwhelm the stock audio. Once rear speakers are added, the underpowered factory amplifier becomes the weakest link.

This system is designed to fix that properly. Built around Cicada’s high-output CXX65.4 front coaxials, CXX69.4 rear coaxials and the powerful FLX1000.4 four-channel amplifier, this package replaces the factory amplifier and delivers clean, controlled power to all four speakers. The result is a balanced front-to-rear soundstage that stays clear and composed at highway speed — with a solid foundation for future subwoofer upgrades.

What’s Included

• Cicada Audio CXX65.4 – 6.5″ High-Output Motorcycle Coaxial Speakers (Front Pair)
  Premium front fairing speakers engineered for maximum clarity and projection, offering higher power handling and efficiency than standard CX models.
• Cicada Audio CXX69.4 – 6×9″ High-Output Motorcycle Coaxial Speakers (Rear Pair)
  High-output rear speakers designed for saddlebag lid locations, providing strong rear fill and a more immersive listening experience.
• Cicada Audio FLX1000.4 – 4-Channel Motorcycle Amplifier
  High-output, fairing-mounted amplifier supplying the headroom and control required to drive both front and rear speakers cleanly at speed.

• Cicada Audio CHDNAVTVA2B – A2B Direct Connect Harness
  Plug-and-play interface harness enabling direct connection between the ZEN-H module and Cicada amplifiers without cutting or modifying factory wiring.

  Motorcycle-specific power wiring kit providing correct current delivery, fused protection and clean grounding for long-term amplifier reliability.

Why Riders Choose This Setup

A2B Audio Explained (Simple Version)

The Skyline™ OS Infotainment Unit uses a digital audio network known as A2B. While this allows factory audio components to communicate digitally, it also requires a proper interface when upgrading.

• Allows removal of the factory amplifier
