Many aftermarket speakers require more power to operate correctly;But most available headunit with built-in amplifiers are not that powerful to power these this case, and without an outboard amplifier, you could never experience high-quality music reproduction in your this reason , using a separate amplifier comes handy for audio enthusiasts.
My only hope is that in the future you will directly sell PCBs or kits (whether you wish to make a profit or not is your prerogative) and also produce a detailed build guide online so that people still starting out in DIYaudio can use it as a standard next step from making a cMoy.
It is measured in Amperes or Amps for short and the symbol is an A. In general, USB ports support (in a 5V charging mode) an amperage between a 0.5A and a 2.1A. A good portable charger should support at least 1A on every charging port, below that amperage it functions more as an external battery than a charger.
Class B : Class B amplifiers are an enhanced version of Class A amplifiers.Unlike Class A,the output transistors of Class B amplifiers actually turn off for half of every signal cycle which significantly improves efficiency and saves energy,However these amps tend to distort at high frequencies.
