Your boat or jet ski deserves a sound system built for the water. At Kustomz Truck and Auto, we install marine-grade audio systems that are designed to handle moisture, UV exposure and the vibration of life on the water, so your music sounds great from launch to dock.

Marine audio components are purpose-built for the marine environment and are not the same as standard automotive speakers. We carry and install weatherproof marine receivers, speakers, amplifiers and subwoofers sized for your boat's cockpit, bow and transom.

Beyond audio, we install marine accessories including lighting upgrades, depth finders, and other electronics. Bring your boat in and we will assess what is possible.

What's included

  • Marine-grade head units and receivers
  • Weatherproof marine speakers (cockpit, bow, transom mount)
  • Marine amplifiers and subwoofers
  • Bluetooth and app-compatible marine systems
  • Lighting and accessory upgrades
  • Clean, weather-sealed wiring on all installs

Frequently Asked Questions

What is the difference between marine and automotive audio components?
Marine components are built to resist moisture, salt spray and UV degradation. Using standard automotive speakers on a boat will cause them to fail quickly. Marine-rated equipment is essential for water applications.
Can you install audio on any type of boat?
We work on most powerboat types including ski boats, pontoons, deck boats and fishing boats. Jet ski installs are also possible depending on the model.
How long does a marine audio installation take?
Most marine audio installs are completed in one to two days depending on the scope and number of components.
