Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for vehicle audio amplification not purely signaling
Microphones/speakers/amplifiers for general vehicle sound systems classify under heading 8518.
If multifunctional electrical apparatus
Amps with additional processing shift to other electrical machines.
If power supply sections dominate function
If primarily a static converter for audio, may fall under power supply converters.
