Turn your Road King into a true highway surround system without ever bolting on a fairing

The Havoc Roar Stereo 600.4 Immersive System for Road King combines Aquatic AV’s GP1 Bluetooth head unit, 300W 6.5" RGB highway bar speakers, and 300W 6x9" Aquatic AV RGB saddlebag lid speakers, all driven by a 600W 4-channel Aquatic AV amplifier. You get four RGB speakers, front and rear presence, and you don’t have to repaint your saddlebag lids thanks to Aquatic AV’s cut-in kit.

Four speakers, two zones, one very serious Road King.

Why the 600.4 System?

This is the system for riders who want big power, front and rear coverage, and no paint work:

• Aquatic AV GP1 head unit with the same AM/FM, Bluetooth, and USB playback that guys with fairing bikes have enjoyed for years
• 6.5" billet aluminum highway bar speaker pods with 300W Aquatic AV RGB speakers throwing sound up at the rider
• 6x9" Aquatic AV RGB saddlebag lid speakers using a cut-in kit, so you keep your factory lids and factory paint
• 600W 4-channel Aquatic AV amplifier in the saddlebag on the Havoc Roadlock bracket driving all four speakers
• All wiring and hardware included – engineered specifically for Road King
• No front fairing required, no giant bagger build-out—just clean, purposeful hardware on a Road King that still looks like a Road King
• Visual pop from RGB cone illumination front and rear, controllable via Aquatic AV’s app
