Types Of Car Amplifiers

Four major types of amplifier for car subwoofer currently exist in the market. These are:

Class A

These amplifiers are referred to as ‘always on’, meaning they are always active whether there’s any sound coming in or not. These are usually bigger in size, and the least efficient.

Class B

These are better defined as ‘switched’, meaning they can switch themselves off when there is no audio coming in. This results in higher efficiency than class A, but also less audio fidelity for the stereos.

Class AB

These are an interesting hybrid of both Class A and B. The biggest plus of these amplifiers is that even though they are always active, they can decrease the amount of current greatly when there is no output. As a result, these are the most popular, ‘full-range’ amplifiers used in cars, and provide great efficiency.

Class D

Class D amplifier works by quickly switching on and off the flow of current through it to maximize efficiency. However, these amplifiers produce quite the distortion when playing higher frequencies.

How To Choose Car Audio Amp?

While choosing a good audio amplifier for your car, keep in mind the following things:


The Number of Channels

Your preferred amplifier for car subwoofer should come with the right number of channels for your car. The rule of thumb is to have one channel for each speaker, like 2 channel, or 4 channel.

In case of sub-woofers, a mono-block amplifier should be enough. You can also choose multi-channel amplifiers that can support multiple speakers or sub-woofers interchangeably.


The Power Factor

The main reason audio car sound systems sound flat is that your speakers are not getting enough power from the amplifiers.

Your amplifier should have an RMS power rating (that is Root Mean Square – a unit of power for sound systems) that matches at least 75 to 100 percent of your speakers’ RMS rating.


Compatible Head Unit

Check your head units before buying an amplifier. It is best if your head unit comes with a preamplifier or kicker, as it can be connected straight to an amplifier or subs for crisp sound output.

If that’s not the case, you might need a more expensive amplifier with speaker-level output system.


A space Headache

Before buying a third party amplifier, make sure you have enough space for installation of the system.

You can compare the dimensions of the amplifier with the place where you want to install it, for example, under the seats, or in the trunk, before you buy it on a whim.

What To Consider When Buying Amplifier For Car sub woofer?

Your Budget

Keep in mind your budget before going through the products. There’s no point in choosing an amplifier way outside your price range and come out disappointed, right?


Available Space

As mentioned above, you should buy your amplifier and speaker system according to available space. Bigger amps can sometimes look cooler and sound amazing, but if your car can’t accommodate them, ditch that choice.


Streamline Your Expectations

What do you expect from your car amplifier in a car? Crisp sound? Thumping bass? Or out-and-out quality audio? Choose your model according to what you expect to hear as output.


Installation Hassle

Are you going to install the unit with all the wiring yourself or going to get professional help? Depending on the answer to amplifier installation, get a model that takes less time and effort to install.
