Installation Guide

This video shows the general install process used across our Harley audio kits, including amp integration, speaker replacement, and wiring.

It’s provided as a guide only. These systems require experience with wiring and Harley fitment, so we don’t recommend attempting installation without the proper knowledge or skill level.

Designed specifically for Harley-Davidson motorcycles, our audio upgrade packages are engineered to deliver clear, powerful sound at highway speeds. Tuned to cut through wind, exhaust, and road noise, each system balances output, clarity, and durability for real-world riding. Every package is purpose-built for the Harley platform, ensuring seamless integration, reliable performance, and music that stays present and controlled—whether cruising through town or riding hard at 110 km/h.

IMPORTANT: Installation & Tuning Considerations

  • All systems require a flash tune of your Harley Davidson ECU to change the source radio output voltage and modify the internal EQ curve to the appropriate settings before installation. This is available as an optional extra from Old School Car Audio here in Perth, or your experienced Harley Dealer.
  • Warning - Amplifier gain settings need to be professionally set to protect speakers at higher power ratings.
  • Consider future proofing your system by installing the 4-channel amplifier version with the DSP, in case you want to upgrade to the 4-speaker kit in the future.
  • All DSP settings need to be measured and setup utilising a professional Real-Time Analyser (RTA). This is available here at Old School Car Audio in Perth, for the ultimate sound experience on your Harley.
  • Modifications to speaker pods are required to fit the GZCF 6.5SPL speakers.
  • Contact us for more specific information on your motorbike and a customised quotation.
