The Pyle PLMR5K 180 W 5.25" 2-Way Marine Component System has everything you need to get started on a high quality marine sound system for your boat. It includes one pair of 5.25" mid-bass speakers, one pair of 1" tweeters, one pair of passive crossover network devices, grills, wires and installation hardware. The mid-bass speakers are powered by a 5.25" poly carbon cone pumping 180 W peak power. The PEI dome tweeters have neodymium magnets for 100 W of sweet highs. Use the passive crossover network to distribute your amplifier's output between the two sets of speakers for an accurate, distortion-free sound.
