Hogtunes G4-RG-RM — QC 225-RM Amp & G4 Front Speaker Kit for Road Glide (2015–2023)
The Hogtunes G4-RG-RM kit is a complete front-stage audio upgrade designed for 2015–2023 Harley-Davidson Road Glide models. This package combines the compact QC 225-RM 4-channel Class D amplifier with a pair of G4 462RG-RM 6.5" front speakers engineered specifically for the Road Glide fairing.
