PBR300 300W Off-Road Audio Amplifier Kit with Bluetooth Controller

Take Amplified Audio on Your Off-Road Adventure

The PBR300 is a revolutionary new product that provides a complete solution for streaming amplified Bluetooth audio from your mobile device to your off-road ProBox tower speakers. The kit includes a 300 watt amp, Bluetooth® and USB/AUX modules that pop into any standard rocker switch slot, fuse holder, RGB LED controller, and all the wiring you will need.

The amp is (2) channel 100 x 100 watts rms at 4 ohms (two tower speakers) and 150 x 150 watt rms at 2 ohms (four tower speakers). Unlike standard marine grade amps, the PBR300 features watertight molded rubber inserts around the wiring and a removeable plexiglass panel with a rubber gasket to protect the gain and crossover controls.

This kit works great with ATVs, side by sides, golf carts, boats, personal watercraft, tractors and more.

With the free EZ LED app, you can use your mobile device to control the RGB LEDs in your ProBox tower speakers. Available for iOS and Android.

Includes everything you need to stream Bluetooth + 300W amplified audio to your off-road ProBox tower speakers:

  • 8 feet of power/ground wire
  • Extended leads and micro port for few connections
  • Fuse holder and fuse
  • Bluetooth audio controller (volume, track, power on/off)
  • USB charging port and AUX input
