5-channel amps

You'll see a lot of options when shopping for an amplifier, and making the right choice depends on what you're trying to do. A 5-channel amp has four channels to drive your four speakers, plus a fifth, higher-powered channel for your subwoofer. They're a popular option for anyone who wants a system with a simple configuration and minimal loss of cargo space.
