Installation Instructions

Step 1: Install the Speakers

Before installation, connect the power cord or SAE connector to a 12V power source to test the speaker. Choose a suitable location on the handlebar, using the appropriate bushing and screws to mount the speakers. The main speaker is installed on the left side of the motorcycle, and the slave speaker is installed on the right side.

Step 2: Connect the Speakers

Plug the speaker connector of the main speaker into the slave speaker. Ensure that the two arrows on each connector align for the correct connection.

Diagram description: The wiring between the main and slave speakers is illustrated. A magnified view shows the main speaker connector and slave speaker connector with arrows indicating proper alignment for connection.

Step 3: Connect to the Turn Signal Light

Peel off the insulated wrap of the purple (right) and blue (left) wires. Connect these wires to the corresponding turn signals on the motorcycle, paying attention to the correct connection for left and right turn signals. The purple wire connects to the right turn signal to control the slave speaker's light, and the blue wire connects to the left turn signal to control the main speaker's light.

Diagram description: The connection of turn signal wires is shown. The purple wire is designated for the right turn signal (slave speaker light), and the blue wire for the left turn signal (main speaker light). Arrows indicate the connection direction.

Step 4: Connect SAE Power Source

Connect the red terminal of the power cord to the positive pole (+) of the motorcycle battery and the black terminal to the negative pole (-). Plug the SAE connector into the SAE connector of the main speaker. Secure and hide any excess cables.

Diagram description: The connection to the motorcycle battery is illustrated. The red wire connects to the positive terminal, and the black wire to the negative terminal. The SAE connector links to the main speaker. A 10A fuse is incorporated into the power cord. A note advises checking the fuse if the speaker fails to power on.

Step 5: Install FM Radio Antenna

Connect the external radio antenna to the antenna connector on the main speaker. Find a suitable location on the motorcycle and use the included 3M tape to mount the antenna. Extend the antenna for optimal FM reception when in use.

Diagram description: The main speaker's antenna connector and the external radio antenna connector are shown. An arrow indicates to tear off the 3M tape for mounting.

Power and Mode Operations

Power On

Press and hold the Power Button for approximately 1 second. The speaker will announce "Bluetooth Mode" and enter pairing mode. The indicator light will flash green and blue simultaneously for 1 second. Upon powering on, the device defaults to Bluetooth mode and automatically enters pairing mode, indicated by a quickly flashing blue light. Once pairing is complete, the blue indicator light will fade in and out. Each time the speaker is turned on, it will automatically search for and connect with the last paired device.

Power Off

Press and hold the Power Button for approximately 3 seconds. The speaker will announce "Power Off", and the indicator light will keep flashing blue for 1 second before turning off.

Switch Mode

Double-click the Power Button to cycle through three modes: Bluetooth, FM, and USB Music, accompanied by voice prompts.

Dual Bluetooth Mode

The Lexin LX-Q3 can connect with up to two different Bluetooth devices simultaneously. To connect a second device, turn off Bluetooth on the first paired device; it will automatically enter pairing status. Then, turn on Bluetooth on the second mobile phone or audio source, search for LX-Q3, and click to pair. The LED light will flash blue quickly. After pairing, the blue LED light will fade in and out. If the speaker is not connected to a device within 5 minutes, it will automatically power off.

USB Mode

When powered on, double-click the Power Button to switch to USB mode, indicated by a Green LED light. Then, plug the USB drive containing audio sources into the USB port. Note: In USB mode, the speaker will automatically shut down after 15 minutes of music pause. It is recommended that the USB drive only stores audio files.

FM Radio Mode

When powered on, double-click the Power Button to switch to FM radio mode, indicated by a Green LED light. A single click of the Power Button initiates automatic searching, and the speaker will automatically save the found radio stations.

Music Control

Click the Volume Up Button for the previous song and the Volume Down Button for the next song. In FM radio mode, click the Volume Up Button to track forward and the Volume Down Button to track backward. Click the Power Button to pause or play music.

Volume Control

Press and hold the Volume Up Button to increase the volume, and press and hold the Volume Down Button to reduce the volume. Note: Volume control is only effective while music and FM radio are playing.

Turn Signal/Running Lights

Running light: Double-click the Volume Up Button to turn the running light on or off. Turn signal light: This function is optional and depends on whether the wire is connected to the motorcycle's turn signal. Note: The LED running light is on by default. When the turn signal wires are connected to the motorcycle, the running light will be automatically controlled by the motorcycle's turn light signal.

Switch Bass Enhancement Sound Mode

In USB and Bluetooth mode, double-click the Volume Down Button to cycle through EQ sound modes: Loud Tune and Bass Enhancement. The default mode is Loud Tune for outdoor use, and the last setting is not saved in memory.

Power Saving Mode

The system will automatically shut down after 5 minutes in standby mode if there is no operation.

Bluetooth Music Sharing Mode

In Bluetooth mode, two sets of LX-Q3 speakers can simultaneously play the same music through the connected mobile phone.

Turn on music sharing mode

When both sets of Q3 speakers are in Bluetooth standby mode, triple-click the power button of the first Q3 main speaker. It will automatically search and connect with the second Q3 speaker. After the two Q3s are connected, the first Q3 speaker can stream music and control all functions (play/pause, volume up/down, change songs). The second Q3 speaker can only control volume up and down.

Turn off music sharing mode

Triple-click the power button to turn off the Music Sharing mode. Note: The music sharing function is only applicable when you have 2 sets of Q3 speakers and can only be used in Bluetooth mode.
