Features
Open-Air Volume That Stays Clear
High-sensitivity 8" two-way tower speakers help music cut through wind and engine noise, delivering articulate highs and strong midrange presence on the move.
Dial-In Coverage
360° swivel clamps rotate to aim audio where it matters—front seats for driving, or rearward for parked hangouts and campsite listening.
Built for Water and Sun
Marinized materials with sealed, rust-resistant terminals and stainless hardware stand up to splash, humidity, and UV exposure.
High-Output 4-Channel Amplifier
Soundstream SM4.1000D delivers strong RMS power with flexible 2-ohm stereo and bridged operation, giving your speaker setup the energy it deserves.
Tuned Control Onboard
Variable high-pass and low-pass crossovers help tailor the system to your ride, improving clarity and protecting speakers from unwanted low-frequency strain.
