Boss Audio Systems MCK508WB.64S Marine Bluetooth Stereo Package with 6.5 Inch White Speakers

The Boss Audio Systems MCK508WB.64S is a complete marine audio package built around the MR508UABW single-DIN receiver, paired with four 6.5 inch full-range white marine speakers and a dipole antenna. It is designed for boats and other outdoor marine applications where the electronics need to stand up to splashing water without sacrificing sound quality or ease of use.

The receiver features built-in Bluetooth for wireless streaming and hands-free calling, with a built-in microphone so you can take calls without reaching for your phone. A push-to-talk function lets you access your smartphone's voice assistant directly through the unit. The front panel is backlit for nighttime visibility, and the head unit plays CDs in addition to AM/FM radio. Connectivity includes a USB port for a connected music library and an auxiliary input for wired devices, plus front and rear pre-amp outputs (front left/right and rear left/right) for connecting the included speakers or additional amplification.

The four included 6.5 inch speakers are full-range, weatherproofed, and finished in white to blend with light-colored boat interiors and helm areas. The package also includes a dipole antenna for AM/FM reception. Together, the receiver, speakers, and antenna give a boat owner a ready-to-install audio system in a single package rather than sourcing each component separately.
