Summary: Everything works fine until you hit a bump. There is no anti skip technology in this unit, so all CDs and USBs will skip at every bumb. Do Not buy this for anything but a car. Very disappointed ...
Summary: I assembled a great marine package for my new boat (new to me, 2004 Larson 21' Lxi) last fall 20013. Did tons of research on Amazon, Crutchfield, etc. Ended up with six, Polk Audio Db 651 6 1/2" speakers mounted aft, under dash and in forward open bow. Running a Kenwood amp for 2 pair and the third pair off this head. Also running a Boss marine amp with 2 MTX 10" subs under my rear bench.
Summary: Just got my radio and they upgraded it for the same cost. Will report back when I get it installed and running. I purchased Kenwood speakers also that way it would complement the radio. I am replacing a Dual radio and speakers.
Summary: I shopped for Marine Stereo for 4 month before buying. This was the Best Deal out there price and quality. It was very easy to install, all wiring is marked, mounting bracket fit and secures the unit promptly. I hope this stereo last a long time but if not I would buy the same unit tomorrow.
