Review on 🔊 2-way IP-X4 Waterproof Bluetooth Marine Speakers - 6.5 Inch, Weather Resistant Outdoor Audio System with 600 Watt Power, Low Profile Design - 1 Pair, White - Pyle PLMRBT65W by Carl Ferguson

I put them inside my sailboat. I was surprised that the active has blue teeth, but the passive needs to be connected to the active. I thought they both communicated through the blue tooth. So you still have to route the cable from active to passive. Wire is included (9.8ft) but I had to purchase more to get the mileage I needed. So it would be very easy to install without trying this step of figuring out where to route the wire on the sailboat and still being able to hide it nicely.
