Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. 2. The measurement allowed error is 1-2cm.3. Safety First: Disconnect the car’s negative battery terminal before starting any wiring work. This prevents electrical shocks, short circuits, or damage to the amplifier/vehicle electronics.4. Check Compatibility: Confirm your car’s electrical system operates at 12V DC (standard for most vehicles) to match the amplifier’s voltage requirement. Verify that your speakers’ impedance (ohms) aligns with the amplifier’s minimum rating (refer to the product manual for specific values).5. Gather Tools & Materials: Prepare essential tools: wire cutters/strippers, crimpers, electrical tape, zip ties, a drill (if mounting), and a dedicated fuse (as specified in the manual). Use high-quality wiring: minimum 8-gauge power cable, 16-18-gauge speaker wire, and shielded RCA cables to reduce interference.Post-Installation Checks & Debugging:Reconnect Battery: After all wiring and mounting are complete, reconnect the car’s negative battery terminal.Initial Testing:Turn on the car and Android device, then gradually increase the amplifier’s volume. Check for distortion, humming, or no sound:Distortion may indicate mismatched speaker impedance or incorrect EQ settings.Humming/static often stems from poor grounding, crossed wires, or unshielded RCA cables.No sound: Verify all connections are secure, fuses are intact, and the amplifier is receiving power (check LED indicators).Final Adjustments:Set the amplifier’s gain control to a moderate level (avoid maxing it out) to prevent clipping.Use the 3-band EQ to fine-tune sound, but avoid extreme ±12 dB adjustments—this can strain speakers and the amplifier.
