How do you bypass the factory amp?

To bypass a factory amplifier, locate the factory amp and disconnect it from the vehicle's wiring harness. You can then connect the speaker wires directly to the head unit or use an aftermarket wiring harness that matches your vehicle's specifications. Ensure proper connections to avoid damage, and if needed, use a line output converter to adjust signal levels for aftermarket speakers or amplifiers. Finally, secure all wiring and test the system to ensure it functions correctly.
