MB QUART GMR1.5S2W Marine Gauge Receiver w/ Bluetooth+(2) White 6.5" Speakers [Open Box]

This kit bundles the MB Quart GMR-1.5W Bluetooth gauge mount receiver with a matched pair of white 6.5 inch coaxial speakers, giving a complete 160 W audio system in one box instead of separately sourcing a source unit and speakers. The receiver mounts into a 3.14 inch gauge hole with a 2.99 inch mounting depth and streams from any Bluetooth device with a 32 foot range, plus USB and RCA aux inputs for wired sources. Its four built-in amplifier channels power the included speakers directly at up to 40 W RMS per pair, with a separate subwoofer RCA output left over for adding bass later. The speakers use 6.5 inch water-resistant composite polypropylene cones and 0.75 inch composite dome tweeters, rated 35 Hz to 21 kHz with 89 dB sensitivity, and their integrated grilles are UV treated so white housings won't yellow or split in the sun. Both the receiver and speakers carry IPX67 marine-grade water and dust protection, making the kit suited to boats, RVs, and other open-air installs where the source unit and speakers face the same weather.
