Designed for personal watercraft, this sound system from WaveAudia requires no drilling! System connects to the headphone jack of any iPod, MP3 player, or iPhone and plays your favorite tunes on the water. 100% digital amplifier means a low power draw.

Volume switch can be placed in a convenient location that allows the rider easy control. Speaker pods are removable, and the low-profile mounting blocks won't interfere with your PWC cover. Includes waterproof MP3 case to keep your music source safe as you ride.
