When your buddy barely landed the last trail bump in front of you, it’s important to get on the horn and let him know you saw it. More amplified than the common 7-watt horn, this system can create a genuine 20 watts of output volume, making it nearly three times as loud. Weatherproof and designed to hold up in the elements, you’ll be able to broadcast to your buddies even in the middle of a downpour. We recommend connecting the horn amplifier to a switched 12-volt power source using the included power leads.

  • Amplified PA horn for genuine 20 watts of volume

Worth it!

Purchased the 15watt standard PA speaker few years ago and now need the 20 watt amplified speaker. This speaker is worth every penny. Always pleased with Right Channel Radios.
