Plug and play stereo sound for your cruiser or ATV! Connect the power leads to your battery, connect the speakers to the harness, connect desired accessories, mount the speakers on your handle bars, engine guards, or other frame member, power on, pair with your mobile phone via Bluetooth, and immediately be able to enjoy your music as you cruise! The LEXIN LX-S3 bar-mount speakers provide great sound and look great! On the side of the left speaker there is a control knob for power on/off, Bluetooth pairing, volume control, play & pause. The fully integrated wiring loom provides easy installation with very few connections required. Charge your music player or mobile phone with the included USB power port, or plug in a USB stick filled with songs. You can even use any music player that has a headphone jack with the built in AUX 3.5mm jack!
