MB Quart's NA3-560.4 marine amplifier can send four speakers 70 watts each to keep the music playing no matter where you are. This rugged and compact amplifier utilizes a number of technologies that ensure normal operation no matter what the conditions are — like over\/under voltage protection, thermal slow-down (not shut-down), and current limiting on the outputs to protect speakers.\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eVersatile amp\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eYou can configure this amplifier as a 2-channel amp and send 280 watts each to a pair of tower speakers, for example.
