4.1. Power and Signal Connections

• Fil wouj: Connect to power positive (DC 6-16V). For car installations, this is typically connected to the car's 12V power positive (e.g., ACC fuse box).
• Fil nwa: Connect to power negative (ground).
• Fil jòn: Connect to the right channel audio input (speaker +).
• Fil blan: Connect to the left channel audio input (speaker +).

4.2. Audio Signal Input Recommendations

For optimal performance, it is recommended to connect the audio signal to the front level (pre-amplifier output, such as from a computer or mobile phone). Connecting to the back level (amplifier output to speakers) is also possible, but be aware that the display effect may vary depending on the frequency range (treble, mid-range, bass) of the connected speaker output. For example, connecting to a treble output might not display bass instrument sounds, and connecting to a bass output might not display vocal sounds.

4.3. Dual Channel Flashing

• For both channels to flash together (mono effect): Twist the yellow and white wires together and connect them to a single speaker's positive (+) terminal.
• For independent left and right channel flashing (stereo effect): Connect the yellow wire to the positive (+) terminal of the right channel speaker and the white wire to the positive (+) terminal of the left channel speaker.
