This JBL marine audio package has everything you need to start building a great-sounding system on your boat. The rugged, easy-to-use marine receiver and powerful 6-1/2″ speakers will stand up to sun, spray, and rough weather while delivering the performance you expect from JBL. The package also includes an antenna and a dash-mount USB extender.

This JBL marine digital media receiver packs a lot of cool features into a compact, weather-resistant design. You can check out AM/FM/WB radio, or you can use the USB and auxiliary inputs to access the tunes stored on your phone or music player. This WAKE series receiver also sports the latest Bluetooth® 5.0 technology, so you can listen to music streamed from your smartphone or other device.

The R3500 also includes a pair of rear-mounted preamp outputs, so you can expand your system with a marine amp in the future. The black and white LED display is easy to read in all lighting conditions, while the IPX7-rated face and controls will stand up to the elements for seasons to come.

JBL’s MS6520 speakers are made for use in the harsh marine environment. Designed to handle sun, spray and scrub-downs, these powerful speakers feature waterproof motor structures, a one-piece cast-polymer basket, a sealed magnet, and durable rubber surrounds. This design delivers full bass response, while maintaining excellent resistance to sunlight and moisture.

JBL is known for great sound, so it’s no surprise that they put some of their best thinking into these marine speakers. Patented Plus Oneâ„¢ polypropylene cones give you an impressive speaker-cone area, so you can enjoy higher sensitivity, increased low-frequency thump, and a richer overall listening experience. The weather-resistant dome tweeters are mounted on the grilles, so you’ll hear all the musical details.

JBL tests all their marine audio gear to make sure it’s tough enough to survive life in the marine environment. This rugged stereo will stand up to storms, spray, sun, and even the occasional spilled beverage, so you can relax, have fun, and crank some tunes.
