Hogtunes G4-SG-RM – QC 225-RM Amp & G4 6.5" Front Speaker Kit for Street Glide (2014–2023)
Hogtunes G4-SG-RM — QC 225-RM Amp & G4 Front Speaker Kit for Street Glide (2014–2023)
The Hogtunes G4-SG-RM is a complete front-stage audio upgrade built specifically for 2014–2023 Harley-Davidson Street Glide models. This kit pairs the QC 225-RM 4-channel Class D amplifier with a set of G4 462SG-RM 6.5" front speakers engineered for the Rushmore Batwing fairing.
With a Street Glide–specific amplifier mounting plate and a true plug-and-play harness, installation is clean and requires no modifications. The G4 speakers offer improved midbass, smoother highs and greater overall clarity compared to factory Harley speakers.
