How to bypass factory amp without harnes

To begin, it’s important to know that bypassing the original amplifier is usually a 
simple process. Other times, it’s a nightmare if you don’t have the right adapter.

The problem is that if your car has a nice audio system with a subwoofer and you opt to bypass the amplifier without using the correct harness (which may cost up to $100), the receiver will only drive the four speakers and not the subwoofer.

If you want to bypass a factory amp without a harness, simply follow the 

Procedures below:

  1. First of all, you need to find the best place to locate the amplifier
  2. Disconnect the head unit
  3. Check the connections between the wires (harnesses)
  4. Determine which wires supply electricity and which ones serve as a ground for the amplifier
  5. Recognize the input cables.
  6. Speaker wires must be checked.
  7. Cross the wires in a criss-cross pattern
