Nautic Marine & Powersports

MB Quart and the Nautic name have been synonymous with having great music in boats and also off-road vehicles. Whether you are outfitting a small fishing boat or an off-road vehicle (designed for flying off dunes and entertaining at the Camp fire) MB Quart offers a wide variety of products that will make your system sound great and be heard over the next hill or into the next cove.


Start with your choice of AM/FM Source Units and Bluetooth controllers. Next, choose from four different solutions for speakers and a line of subwoofers to really feel the music. To power the system there are amplifiers in classic white marine. Also, a line of very small amplifiers perfect for off-road vehicles is available.

One of those speaker choices is our most unique yet. The Point Source Technology, Coincident Mounted Compression Horns are designed to deliver a high amount of SPL while delivering a full range of frequencies. Here is a quick look at all of our categories.

The Coincident Mounted Compression horn keeps all energy focused forward, improving the sound pressure, whether you are in a boat at the end of a ski rope or on an UTV with a helmet.
