Nautic NA3 Amplifiers

AUDIOPHILE MARINE STANDARDS
Nautic amplifiers are not automotive amplifiers. While they will work just fine in a car or truck, however, they are purpose built to very strict standards set forth for marine electronics by the American Society for Testing and Materials, ASTM International™ and NMMA.

NMMA CERTIFIED
National Marine Manufacturers Association (NMMA) is a voluntary consortium of global boat manufacturers that set standards for marine products, from boat building to the accessories installed in them. In terms of marine audio amplifiers, NMMA defines the safety requirements which means that your MB Quart marine amplifiers are held to a higher standard that typical audio products for delivering power from the electrical system, through the PC board to the speakers and subwoofers.

CONTROL & EXPANSION
Sound contouring with onboard crossovers, bass boost and adjustable input sensitivity are all concealed behind top mounted controls. All of this control will allow you or the installer to fine tune the system using a myriad of variable frequency adjustments along with level controls within the EQ range and Bass EQ active at 45Hz while in LP/BP operation.

Nautic amplifiers are available in 4, 5 and a 6 channel configurations so you can drive speakers on the deck or in the cabin and have plenty of power for subwoofer channels. With the MB Quart source units and Bluetooth controllers it is possible to have better audio experience on the water, the solution has always been Nautic from MB Quart.
