How to Bypass Factory Amp Without Harness

Rate this post

To bypass a factory amp without a harness, you can connect a new aftermarket head unit directly to the speakers. However, this method may not provide sufficient power.

Alternatively, you can remove or bypass the factory amp and replace it with your own aftermarket amp if there are no digital connections between your radio and the amp, and the amp’s input signals respond to the radio’s volume control.

By tapping into the stereo’s speaker outputs for the amp’s input signal and sending the amp’s outputs back to the stereo’s harness, you can connect an aftermarket amp to a factory stereo effectively.
