Review on GoHawk TJ4 R Amplifier Waterproof Motorcycle Car & Vehicle Electronics by Jason Mitts

The volume exceeded my expectations. Receives AM and FM radio. The Bluetooth works great. The manual switch doesn't light up at night, so trying to turn up the volume is like reading braille, but the buttons are easy to remember. There was more than enough cable to run the power cords and speakers. The only real complaint is that the handlebar mounts need more rubber damping, the speakers move a lot due to engine vibration. And mounting the speakers requires three hands. You may need help.
