– Hey, welcome back to Car Audio 101. I’m Alan with Sonic Electronix, and today we’re gonna be
talking about amplifiers. (upbeat music) So, you might be asking,
what’s an amplifier and why do I need one? So, an amplifier essentially
does what it’s called. It amplifies. It takes signal from a source unit, which is typically a low-voltage signal, it amplifies that signal
to a much greater signal. Read this article to know about the best 5 channel car amplifier. Now, I can’t say specifically
what the output would be that it’s gonna amplify ’cause amplifiers come in many different sizes. It could be 75 watts,
it could be 100 watts, it could be 1,000 watts,
it could be 5,000 watts, but essentially all it’s doing
is taking the low-voltage signal and amplifying that
signal to power either your speakers or your subwoofers. While some speakers can run off low power, just from your car stereo
alone, amplifying your speakers will really bring
out their full potential and make your system shine. On the other hand, your
car stereo will not be able to power a
subwoofer, so an amplifier will always be required. So the benefit of an
amplifier is to give your system the power that it needs. If you give it the power that it needs, it’s really gonna sound a
lot louder, a lot cleaner, and you’re gonna have way less distortion, not to mention the filters
that are built into the amplifier which will
really allow you to dial in and tune your system to sound its best. So, one of the things
you’re gonna want to look at when shopping for an
amplifier is how many channels the amplifier has and
how much power output the amplifier has also known
as watts, or RMS power. The most common
configurations on amplifiers are four-channel,
five-channel and mono blocks. Mono blocks are a single
channel amplifier. Typically one channel would run one speaker or one subwoofer. As an example, on a
five-channel amplifier, a five-channel amplifier
would typically be connected to four speakers and one subwoofer. From there, amplifiers are
pretty much broken down into classes. So, here’s a few examples. Class A, Class AB and Class D. But we’re gonna touch more on those in detail a little later. So, when shopping for an amplifier, it’s really important to
match up all the equipment, look at the amplifier,
look at the speakers, look at the subwoofer
you’re potentially running with the best amplifier for car, so everything’s powered
properly so you can maximize your system and
get every bit out of it so it can sound its best. So, we’re gonna go over
all of this in great detail on filter settings,
amplifier classes, power, matching audio components to
set up a whole entire system on future Car Audio 101
