The Pyle PLMR6K Hydra kit has everything you need to get started on a high quality marine sound system for your boat with the water-resistant construction. It includes one pair of 6.5" 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 6.5" polycarbon cone and 1" high-temperature voice coil pumping 200 watts peak power. The PEI dome tweeters have neodymium magnets for 100 watts of sweet highs. Use the passive crossover network with waterproof ABS housing to distribute your amplifier's output between the two sets of speakers for an accurate, distortion-free sound.
