Rock out when you're outdoors: Infinity's INFPRV315.2 marine digital media receiver gives you plenty of ways to enjoy music on your boat, plus a color screen, a built-in 2-ohm stable amp, and the inputs you'll need to expand your system later. Built-in Bluetooth with ID tagging lets you stream music from your smartphone, or you can use the AUX or charging USB inputs to enjoy tunes stored on a music player or thumb drive. You'll also be able to enjoy your favorite radio stations and track weather on the global AM/FM/WB tuner.
