Give your nautical journeys a boost with a new pair of marine speakers. Alpine's SPS-M600 6-1/2" marine speakers use a time-tested design to boost the performance of your boat's audio system.

Alpine equips its speakers for high power handling, so they'll cut through the noise of the wind, waves, and motor. The stiff 6-1/2" polymica woofers deliver powerful, accurate reproduction, while the titanium/PEI tweeters supply plenty of high-frequency detail.

Alpine built the SPS-M600 speakers to withstand the tough environmental conditions of life on the water. The speakers sport UV-resistant grilles and high-temperature custom frames that stand up to direct exposure to the sun, while Santoprene rubber surrounds resist damage from moisture, heat, and motor oil. Your speakers won't turn yellow or lose any musical zip.
