Pro Tip: If your vehicle has a factory amplifier, do not connect these speaker wires directly to the car’s harness. Instead, use the Blue (A5) wire to trigger the factory amp, then tap into the amp’s input or output wires separately.
Solution: Check the fader setting, then verify that your car’s factory amp is being triggered. Leave the Napa65’s blue wire disconnected if your car has a factory amp without a remote turn-on – instead, use a speaker-to-line output converter.
