At the highest level, and easiest to understand, amplifier classes are as follows:
Digital Sound Processing amplifiers go a little bit further than your average car amplifier. They perform like any other amplifier, taking input from your head unit, increasing the power in the signal and delivering more power to your speakers, but along the way, they add some secret special sauce to the signal increasing the fidelity performance; making your tunes sound better.
Some DSP's are able to connect up to 8-Channels and produce some true audiophile level results. These units are almost exclusively tuned via a connected laptop and specialist software. A little bit of overkill for your 2017 Toyota Corolla... unless you're entering Sound-Off competitions.
Almost exclusively used as subwoofer amplifiers, these units produce a whole bunch of power across one channel. These amplifiers are able to run at lower impedance resulting in higher nominal (WRMS) and high peak performance.
Depending on what you're installing, you may need more channels. For instance, if you're installing new speakers and want them to be amplified, you'll be shopping for a 4-Channel amplifier; one channel for each speaker. If you're adding a subwoofer to your amped speaker system, a 5-Channel is for you.
