Why buy a good car amplifier?
The role of a car amplifier is to amplify electrical signals transmitted by your car’s audio unit to deliver more power to your car speakers.
Not only does the amplifier produce more power, but it even improves the sound quality and allows you to connect a larger number of speakers. Most cars are factory-equipped with a powerful enough amplifier for standard speakers.
Installing a new car amplifier is usually done when you want to upgrade your factory car speakers. If you want to add more bass sound to your car, you can use a car amplifier on a single channel that can connect to a car subwoofer.
The professional installation of a car amplifier is recommended to ensure that you do not damage your equipment by improper wiring. Incorrect installation of audio equipment in the car can also lead to accidents and injuries.
The Best Car Amplifier: What to Look for
Most of the cars are equipped with integrated amplifiers in the audio unit, but adding an amplifier is about adding an external stand alone amplifier. It must be compatible with the audio system present on the car and you need to consider the number of channels and the power you want.
If you like an awesome sound, you’ll have to choose an amplifier with a dedicated channel for low sounds (bass). Knowing from the beginning what you want will help you choose the best car amplifier for you that will deliver the desired sound.
Number of Audio Channels
The best car amplifiers are equipped with a specific number of channels. These channels refer to the number of audio outputs or the number of speakers you can connect to the amplifier. Each channel includes two speaker terminals (one positive and one negative).
A mono amplifier usually offers a single channel and is used most often to add a subwoofer. A 2 channel amplifier (stereo amplifier) is used to connect two car speakers (one on the left and one on the right).
Multichannel car amplifiers can have two to six channels in this way that can couple a whole complex audio system. The latter are quite bulky and require more space for installation.
The maximum power of a car amplifier is given by RMS (power) or total output power to each speaker. It is important to know the amount of RMS power of the speakers you own and then to choose an amplifier that has a power of at least 75% of that power.
For example, if your loudspeaker has a power of 150 watts, you’ll want to buy an amplifier that can generate between 125 and 175 watts of power per speaker (or channel). If you do not pay attention to these values, you will not get the best results for your car’s audio system.
Warranty and Service
Warranty of the chosen car amplifier protects you if it fails after it has been installed in your car. Depending on the warranty conditions, some manufacturers also provide warranty for damage to car speakers if they happen due to a manufacturing failure of the amplifier, provided that the installation has been made by professionals.
Take great care of who you buy the car amplifier from, many manufacturers have the mandatory requirement to purchase from an authorized dealer to provide the warranty for the product.
Although factory-installed car amplifiers are much better than they once were, buying an additional car amplifier will help you get the most out of your car audio system. Making an informed choice you can be sure that you will choose the most suitable car amplifier for you.
