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 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.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

This marine digital media receiver will not play CDs.

    8 questions already asked

    Are these speakers bi-wired?
    [ David  Jun 06, 2022 ]
    1 answer
    These are NOT bi-wired David, but that's a great question! These speaker's use one positive and one negative for power. You can drive a total of four 4ohm marine speakers with the INF-MPK250, you just get two in the kit! Room for some adding in the future if you need.

    Fusion ms-ra205. How do I get I pod to play ?
    [ Scott  Aug 12, 2020 ]
    1 answer
    With the iPod connected by wire select aux mode on radio and turn the volume to max on the device
    [ JEFF  Aug 13, 2020 ]
    Can this unit run 6 speakers properly? My boat already has 4 speakers and wanted to add 2 more.
    [ P Milbs  Apr 25, 2020 ]
    1 answer
    This receiver can only power 4 speakers. It does have an audio output that can be used to connect an amp to power more speakers.
    [ Paul  May 12, 2020 ]  Staff
    Can the 4 channels be bridged to provide 40 rms to two speakers?
    [ Surfrider82  Oct 08, 2019 ]
    1 answer
    No, the built-in 4-channel amp can not be bridged.
    [ Cosmo  Oct 18, 2019 ]  Staff
    Will this stereo connect with the Infinity Basslink DC? If so, via what stereo input/output?
    [ Mike A  Nov 29, 2016 ]
    1 answer
    The Infinity does offer a pair of RCA pre-amp outputs you can use to provide the audio signal to an external amplifier or powered subwoofer. So, you can use RCA cables for the audio connection. I hope that helps! My Bio:
    [ Ryan  Dec 02, 2016 ]  Staff
    I saw this setup at J&P Cycles. It was demonstrated on an oem windscreen. Literature said it will bolt to an oem windshield for a motorcycle. Is this true with this unit as the picture is identical?
    [ Michael  Jun 12, 2016 ]
    1 answer
    I would not be able to clearly state an documented answer for a motorbike since I install it on a boat. Then again, I can say the unit is compact.
    [ LUIS R  Jun 13, 2016 ]
    I have an audio and USB extension for this radio, however the USB will not charge an iPhone 5. Are there any solutions?
    [ James  Dec 29, 2014 ]
    3 answers
    it is likely the chord you are using, the usb worked fine on the one i purchased and it charged both iphones and androids. try a different chord and see if it works
    [ Brady  Mar 04, 2015 ]
    What amp is recommended for these speaker application
    [ Haywood  Jan 02, 2015 ]
    I have this setup in my bass boat and I just ran an additional power outlet and used my iPhone car charger. You could also install I high output USB wall jack from a local electronics store and run it directly to battery with a inline fuse
    [ thomas  Dec 30, 2014 ]
    I have a "standard" size receiver now... will this receiver fot in its place, or is there a trim kit?? Thanks
