Improving Sound Waves While Riding the Waves

Being on a boat can be pretty loud with the sound of the motor running and other boaters within your vicinity making noise. So you buy some speakers and they sound great but you really can't make out any of the bass coming from you audio source. Lucky for you Rockfod Fosgate has the perfect solution to your problem. This 12", marine rated, M2 series subwoofer is rated at 300 watts RMS which will vastly improve the bass output in your audio system. The woofer is equipped with an injection molded mineral filled parabolic polypropylene cone for rigidity and improved performance. The UV and salt-fog resistant TPE surround is built to take the harsh environments of the sun and ocean giving your subwoofer longevity. The sleek black finish makes it compatible with just about any boat interior, while its speaker grille adds some protection from possible objects rolling around the deck. Don't let your audio system go to waste with weak bass, Rockford Fosgate's M212S4B is the perfect way to add some bass that is enjoyable, crisps, clear, and responsive.
