What is difference between 2 channel and 4 channel amplifier?
A 2-channel amplifier will be the practical solution when you only need to power a single pair of speakers. But if you like rear-fill sound in your car and want to retain front-to-rear fade control, get a 4-channel amp — one channel for each speaker.
What is a 4 channel amp?
A 4 channel amplifier is a stereo amplifier with 2 more channels built in to boost (amplify) weak input signals to a higher voltage signal. This drives speaker voice coils to move the speaker cone and produce sound.
What is a 3 channel amp?
A 3 channel amp is constructed as a two channel AB amp up front, and has a third channel on the rear channel like a Class D amplifier. The main difference with a 3 channel amplifier is the application of two speakers and one subwoofer.
