When I first considered upgrading my car audio system, I knew I wanted a 4 channel amp door speaker setup. It became clear that this configuration would provide balanced sound quality and sufficient power for a great listening experience. I realized I needed to evaluate my listening habits and the kind of music I enjoy.

Assessing Power Requirements

Determining the right power output was crucial for me. I learned that the power of the amplifier should match the speakers’ capabilities to avoid distortion.
