A complete Bluetooth amp package that only requires a 5/8" hole in your dash! Aside from the included speakers, the power/pairing switch is the only visible element of this sleek unit. The amplifier can be mounted on any flat, sturdy surface that won't be submerged or subject to excessive heat. 

The compact 40W per channel amplifier is built to handle the most rigorous of
conditions. The 5.25" speakers are waterproof (IPX6) and compliant to ASTM B117 Salt Spray Exposure Standard. Operating Voltage: 10 – 16VDC.
