Marine & Powersports:
Weatherproof Systems

From navigating the dense fog of Prince William Sound to tearing up the dusty UTV trails of the Mat-Su Valley, we engineer waterproof, dust-proof, and high-vibration marine electronics and audio systems built for the Alaskan wild.

Extreme Proven Workmanship

Iron Dog-Tested Powersports Engineering

Owner **Kevin Lembke** and the Hillside Audio crew bring active experience engineering custom electronics packages that survive the **Iron Dog**—the world’s longest, toughest snowmobile race. We apply these exact high-vibration wiring methods, sealed Deutsch connectors, and reinforced power isolators to every UTV, ATV, and powersports installation we build.

Sealed Deutsch plugs (salt & mud-proof) Solder-fused connections (vibration proof) High-amp isolated circuits

Saltwater-Grade Marine Audio

Standard boat speakers corrode and distort within one season in Kenai or Cook Inlet. We install premium, UV-stable, saltwater-resistant JL Audio MX and M6 marine speakers, waterproof subwoofers, and class-D marine amplifiers designed to project clear sound over engine roar.

  • JL Audio marine-certified systems
  • Stainless steel hardware and salt-resistant grills
  • Zone-controlled audio (helm, cabin, tower, deck)

Garmin Navigation & Sonar

Navigate Alaskas unpredictable bays safely. We install Garmin ECHOMAP chartplotters, high-definition transducers, radars, and VHF marine radios. Ensure clear bottom tracking and reliable GPS positioning in Prince William Sound and Resurrection Bay.

  • Garmin authorized dealer & certified installation
  • In-hull, thru-hull, and transom transducer setups
  • NMEA 2000 network integrations for engine data

IP67 Waterproof UTV Speaker Pods

Equip your side-by-side (RZR, General, Can-Am, Pioneer) for the dusty, muddy trails of the Mat-Su. We install heavy-duty, clamp-on roll-bar speaker pods, Bluetooth controllers, and compact under-seat subwoofers engineered for dust, mud, and water immersion.

  • Kicker & Rockford Fosgate powersports systems
  • Roll-cage clamping hardware and heavy-gauge wire runs
  • Auxiliary battery backups for engine-off listening

Underwater & Accent LED Lighting

Transform your boat with high-intensity underwater LEDs (blue, green, RGB) and interior cabin accent strip lighting. For UTVs, we install high-impact RGB rock lights, heavy-duty whip lights, and integrated switches with smartphone controls.

  • Bronze or polymer underwater housing installations
  • Smartphone app controllers for customizable colors
  • Ignition-isolated circuits preventing battery drain
