⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier to the impedance recommended by the manufacturer and to use the recommended wiring gauge. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is strongly advised to adapt the electrical supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and ensure optimal performance. WARNING: Any voltage drop below 12V can damage the product.
