Class AB vs Class D sound quality is one of the most common debates in car audio. Class AB amplifiers are known for their warm, natural sound and excellent clarity, making them a favorite for audiophiles who prioritize pure audio performance. On the other hand, Class D amplifiers are highly efficient, run cooler, and deliver powerful output, making them ideal for subwoofers and modern high-power setups. While Class AB often edges ahead in sound refinement, Class D has improved significantly and now offers impressive sound quality with much better efficiency. The best choice depends on whether you value pure sound accuracy or power and efficiency in your system.
