Basically a 4-channel amp and a monoblock amp combined. Allows an entire system to be powered from one amplifier (4 speakers, 1 or more subwoofer) Good for those who don't want multiple amplifiers powering their entire system.
Secondly, is a 4 channel amp worth it?
If you're looking simply for more power for your front and rear speakers, a 4-channel amplifier is the way to go. ... 100-up watts per channel amps are for when you want your music boosted to competition-level volume.
Yet, how many speakers can a 4 channel amp power? 8 speakers
Well, is a 2 channel amp better than a 4 channel amp?
All the difference is about the number of the channel which connects with the number of speakers or subwoofers. A 2 channel amp can join with fewer speakers whereas a 4-channel or more-channel can connect with more speakers or more subs. Two speakers, one sub.
Can you run 2 subs off 4 channel amp?
Minimum speaker loads for wiring a 4 channel amp to 4 speakers and a subwoofer. ... As I mentioned above, most car amps today can handle a 2 ohm load per stereo channel (left & right channels) and 4 ohms minimum when bridged to drive an amplifier (called “mono”).

When choosing an amplifier, the most important thing is to pick one with the right amount of power for your subs. Once you've decided how much power you need, you'll need to decide which type of amp to use. For most bass systems, you'll want to choose either a mono (single-channel) amp or a 2-channel amp.
80 watts of power is more than enough for most applications. But the real #'s that count are the sensitivity of your speakers and the powerband of the amp. If you speakers have a sensitivity of 88db they will sound half as loud as speakers with a 91db sensitivity.
