About the Infinity 622MLT
Reference sound, really cool lights
Reference sound, really cool lights
These marine-rated Infinity Reference 6-1/2" speakers will bring great sound and cool lighting to any vessel. Made for outdoor use, these rugged speakers can handle up to 75 watts RMS and they're designed to cut through wind and engine noise when you're out on the water.
When you buy Infinity Reference speakers, great sound is a given. But these speakers also give you attractive RGB LED lighting that'll add style to your boat.
Ready for the outdoors
Compared to car speakers, marine speakers live a pretty harsh life. There's sun, spray, salt, and extreme temperatures, plus the occasional fish that gets loose on the deck. These Infinity speakers are ready for all of it, with one-piece polymer baskets, marine-ready componentry, and UV-resistant grilles that will stand up to spray and punishing sunlight for years to come.
These marine speakers are available in Titanium or White.

Product Research
Features
Tweeters: The balanced dome tweeters are bridge mounted to the grilles, rather than to a pole piece, thus there is no chance of water leaking through the woofer cone.
LED Illumination: Integrated into each grille, on the back of the tweeter casing is a red/green/blue LED assembly, to create a glow on the woofer cone. A 12 volt power supply is needed to turn the LEDs on; depending on what combination of LED wires is connected, they light red, green, blue, yellow, purple, aquamarine, or white. A 4-wire pigtail is provided for supplying power to the built-in LEDs.
Size: With a required cutout diameter of approximately 5", these speakers fit into the openings for standard 6-1/2" car speakers, but the frame is much bigger than a typical 6-1/2" and the screw hole pattern is different. Because the grille is not designed to be removed, the mounting height is also greater than most car speakers. For these reasons, the speakers won't fit in most car applications.
