Hear Your Beats Clearly Over the Noise of Having Fun
When cruising through waves and wind, you want to hear your beats clearly over the noise of having fun. MB Quart's NA3-750.1 marine subwoofer amplifier gets the job done by sending your sub up to 750 watts of bass power. And 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.
