Tips for Buying an Amplifier for Your Car Stereo

An amplifier is an electronic device that is used to provide power to speakers for maximum sound quality. An amplifier is capable of receiving sound signals from the source of the audio and increasing the sound waves without distorting them before transmitting them to the speakers. This function of an amplifier essentially results in a much louder yet cleaner sound output.

Notice the poor sound quality given out by speakers without accompanying amplifiers. This difference is especially discernable when the speakers’ volume is put to its maximum. If you want to maximize your listening experience while stuck in the notorious city traffic to and from work, then consider doing yourself a favor by getting your car an additional amplifier to complement your car stereo system.

• The first consideration is audio power. When talking about audio power in terms of amplifiers, there are two industrial ratings used – the RMS (Root-Means-Square) Power and Peak Power ratings. RMS Power is measured in watts. It represents the electrical capacity the amplifier is able to absorb and give out without failure or interruption under normal operating conditions. Peak Power on the other hand is the maximum amount of electrical power the amplifier is able to accommodate when it is pushed to its limit. It is very important to consider the audio power ratings not only to maximize the amplifier’s full functionality, but to protect the speakers as well. Too much audio power and your speaker system will surely explode. When buying an amplifier, it would be best to take the RMS Power into consideration as Peak Power rating is quite misleading. Bear in mind to match the amplifier’s RMS Power rating with that of your car stereo’s speaker system.
• The next thing you need to look at when buying an amplifier for your car stereo are its channels. The number of channels available in an amplifier will determine how many speakers can be hooked up to it. Newer models of amplifiers have now equipped each channel with both the right and left signals for that surround sound feel. If your car already has existing speakers, then you might as well check how many there are so you know specifically which amplifier to purchase.
• The other thing to look for is heatsinks in an amplifier. Since amplifiers generate and store electrical charge to accommodate fluctuations in the audio being played, heat is naturally produced. And as we all know, heat is the greatest enemy of any electronic device. In most cases, an amplifier that feels heavy enough is likely to be installed with sufficient heatsinks.
• Lastly, consider getting an amplifier with the preamp provision. This will allow you to extend the signal chain and add more sound enhancing equipment to your car stereo. This is just in case you intend to pimp your ride by adding more amplifiers in the future.
