Car audio upgrade is a technical work, often involves including power amplifier host, speaker, space and frequency divider, shock absorption and other aspects of the upgrade, in fact, in the car audio system, the power amplifier is the least important factor, the size of the distortion on the entire system is minimal, and generally difficult to detect. However, several other aspects, especially the biggest impact of the speaker, a good sound system, the investment of the speaker can reach more than 70% of the entire cost. The interior space of the car is complex, many parameters in the design of the defects can not be avoided, therefore, the transformation of the car audio should focus on sound insulation, sound absorption, horn upgrades, etc., and try not to change the location of the horn and additional new facilities, otherwise, because of wiring problems caused by large accidents. The above suggestions are for reference only.
The original power amplifier chip is TDA7388 maximum power 4*41W\/ 4ω
