Polk Audio DB651 marine boat speakers. These 6.5" coaxial speakers are used but we tested them and they work. One speaker the wires are easy to reach and the other one (check out the pictures) you can see was cut way too short and will need to be replaced. Designed for marine audio systems, these speakers provide high-quality sound performance and durability for boating or fishing trips. The sealed box ensures that the speakers are protected and secure for safe transportation and installation on a boat.
