Marine audio package from Infinity

This all-in-one package from Infinity has everything you need to start building a great marine audio system on your boat. The compact marine receiver and powerful 6-1/2" speakers are made for marine use, so they'll stand up to the harshest elements while giving you the power and performance you expect.

Infinity INF-PRV250 digital media receiver

This digital media receiver packs a lot of features into a compact, rectangular design. You'll enjoy AM/FM radio, of course, plus USB and auxiliary inputs that let you listen to the tunes stored on your iPod, iPhone, or MP3 player. Built-in Bluetooth® lets you enjoy music music streamed from your smartphone or other Bluetooth device.

The INF-PRV250 includes a pair of rear-mounted preamp outputs, so you can expand your system with a marine amp in the future. The LED display tells you what you're listening to with just a glance, while the weather-resistant, UV-stable face and controls will stand up to sun, salt and moisture when you're riding the waves.

Infinity INF-612BC 6-1/2" speakers

Infinity's INF-612M 6-1/2" speakers feature a polypropylene woofer cone bonded to a tough, UV-resistant rubber surround. This design delivers full bass response, while maintaining excellent resistance to sunlight and moisture. The corrosion-proof, cast-polymer basket shrugs off deterioration caused by salt, moisture, and UV rays, while the stylish non-removable grille is specially treated to retain its shiny chrome finish.

The grille-mounted 1" tweeter offers excellent high-frequency projection. Infinity seals the front of the woofer cone along with the speaker's magnet structure for extra protection against moisture.

    Crutchfield Customer Review (What's this?)

    Super great quality and loud

    AWESOME!

    Written By PS, Florida on Friday, March 14, 2014

    I was a little hesitant at first as this is not your typical head unit setup but after installing it and cranking it up I am extremely impressed! I love the reliability of Infinity and this is a great kit for anyone looking to start a bigger system or just want something small. I love the blue tooth control; that is by far the best feature!

    I would definitely recommend this setup to anyone!
