Turn up the volume on every outdoor adventure with the BOSS Audio ASK902B.6 Marine Speakers and 4-Channel Amplifier Package. This all-in-one kit brings together the MC900B amplifier and a pair of MR6W 6.5-inch marine speakers with a rugged polypropylene cone and rubber surround to handle lake winds and salt air. The system runs on 4-Ohm stability, delivering up to 125 W per channel peak and up to 94 W RMS per channel, enough to fill open decks with clear highs and punchy mids without the need for an in-dash head unit.

What you get

  • MC900B Amplifier — 4-channel, weather-resistant with MOSFET power supply for consistent performance.
  • MR6W Marine Speakers — 6.5-inch full-range drivers with polycarbonate cones and rubber surrounds for durable, water-ready sound.
  • Inline Multi-Function Remote — control playback without reaching for a deck clutter.
  • Bluetooth streaming and USB charging — play from apps like Spotify or Pandora; charge while you listen.
  • Weatherproof connectors and a marine-grade build — designed to resist corrosion and the elements.

Key capabilities at a glance

  • Power: 125 W Max x 4 @ 4-Ohms; 94 W RMS x 4 @ 4-Ohms; 4-8 Ohm stable with RCA outputs.
  • Bluetooth: Stream directly from phones or MP3 players with the included remote control.
  • Durability: Weather-resistant design and included waterproof pouch for devices.
  • Versatility: Full-range amp that can drive speakers and subwoofers; 3.5 mm Aux to USB/RCA interfaces included.
  • Dimensions and weight: Compact amplifier and speaker footprints designed for boat installations.

Why it helps on land or water

The ASK902B.6 package is built to handle changing environments while keeping music accessible. With no separate head unit required, you can mount the remote in easy reach and connect USB devices or smartphones for playback. The combination aims to deliver crisp highs, solid midrange, and sufficient volume for open spaces, whether you’re cruising the marina or relaxing on a sun deck.

Usage ideas

  • Deck parties after sunset with clear, reliable sound.
  • Dockside gatherings where a compact system matters more than a full car stereo.
  • Weekend boat trips where stereo flexibility and resistance to weather shine.

Warranty coverage is included when purchased through Amazon, with six years on amplifiers and three years on speakers, subject to the seller's terms. Professional installation is recommended to ensure proper function and safety.

FAQ

Q: Is this system designed for boats or can it be used on land?

A: Designed for marine environments, it can also work on land with proper mounting and power.

Q: Do I need a head unit to use Bluetooth?

A: No head unit needed; Bluetooth remote streams from your phone and the USB adapter handles playback.
