Types of amplifiers
There are several
types of automotive stereo amplifiers on the market today.
2 channel, 4 channel,
even 8 channel.
They all however do
the same thing. Amplify sound. Lets start with the 2 channel:

channel amplifiers may also be used to drive a sub woofer
box and the rear speakers.
Other models may contain 6, 8, or more channels.
