A car processor is a device that processes the audio signal from various sources before it reaches the speakers. It includes features such as equalization, crossover, and time alignment to improve the overall sound quality. A car processor can be an excellent addition to any car audio system, especially when used in conjunction with subwoofers and amplifiers.

The advantages of using a car processor include improved sound quality, greater control over the audio system, and the ability to fine-tune sound settings to personal preferences. Key characteristics to consider when choosing a car processor include the number of channels, processing power, and ease of use.
