4-channel car amplifiers Quartorigo

Four-channel amplifiers are the most popular today, especially because of their variability in connection. You can connect a four-channel amplifier for front and rear speakers, or for front speakers and a subwoofer, and in extreme cases for two subwoofers thanks to the amplifier's bridging capability. They can also be used for active connection of one pair of component speakers, when you connect each speaker separately to one channel.
