Technical Notes
- No radio re-flash required if the bike still has the original non-amplified factory 4-speaker profile.
- Class D amplifiers naturally reduce FM reception — this is normal across all brands.
- R.E.M.I.T. circuitry provides the best FM performance available for motorcycle-specific Class D amps.
- Adding additional amplifiers will further reduce FM reception — this is expected.
- Harley’s external antenna always provides the best FM performance.
