Guide To Choose Stereos Car Amplifiers

Here's the guide to choose stereos car amplifiers.

Have you ever been driving your car and suddenly your favorite song comes on the radio? Also first, what is your natural inclination to do? Pump up the Volume, of course! For some this may be a great experience, but for others, and say that maybe left feeling a little disappointed. What is the crucial factor that separates the two? That is good, if you have an amp or not.

Amplifiers are one of the most overlooked components of a good audio system. For those who are still in the factory installed stereo in your car, have you ever noticed that the volume is increased, if at a certain level, you begin to hear strange scratching sounds coming from the speakers? This is the result of saturation. This happens when the amp is out of power and can not meet the requirement of the level of service that you are calling from. This is exactly what happened when they decided to crank up the volume of your factory car stereo amplifier in the radio, with the car you can not the service that you call A. You need an amplifier. So, if we are only in the choice of the best amplifier to our needs? Well, that's what we're here. Here is a guide to buy the best amplifier for their needs.

For those of you with a limited budget, the best place to get through the improvement of the Main Unit, better known as radio. Update on the device can be a substantial increase in performance and a very marked difference in sound quality, even with the factory installed speakers.

Now is the time for great things. For those of you who have already updated your device, but still craving for more power, the best in sound quality, and / or think about a subwoofer to your system, you must create a completely separate amplifiers, or better known as a power amplifier . "It is an independent unit with the exception of his device. These amplifiers are generally well under the seat or in the trunk of his car. The installation is also a little more difficult than installing a new radio.

Amplifiers come in a variety of different flavors. There are many different types of amplifiers and a variety of specifications to deal with them. Given all this information, where to start? The first place to decide the number of channels. Car amplifiers are usually one to six channels. A channel is another name for a speaker. For example, if you want a power amp for the front and rear speakers to buy a four-channel amplifier (the left and right speakers on the front and the left and right speakers on the back). For those who seek power only one subwoofer, it is very likely to buy a channel amplifier, also known as mono amplifier.

Although five and six-channel amplifier is rare to see, offers a solution that allows you to feed your door speakers and a subwoofer with the same device. Anyway, you have to be an amplifier that suits your needs.

After the number of channels that are to be the next thing to consider is the amount of energy they need. The amount of power an amplifier can be measured in watts. In the decision, it is important to ensure that the amplifier is rated CEA. CEA is the Consumer Electronics Association. Have a way of measuring the power amplifier. In essence, make sure that when a manufacturer gives a 100 watt amplifier that is 100 watts. After buying an amplifier from a manufacturer claimed that its production was 200 watts per channel. I bought it and was very disappointed. I could not even my power door speakers to a reasonable level. Then they have him, and bought an amplifier from another manufacturer. If only 50 watts per channel, but CEA was. The difference between the two was night and day. This amplifier has a lot more power than the previous one by the manufacturer. I must be careful, sometimes, or I'll blow my speakers (or my eardrum to the case).

These specifications are the top two most important things that are for the purchase of a power amplifier. There are other important characteristics that I believe should be taken into account, and I will continue below.

Classes of amplifiers

Amplifiers are available in different classes. These classes determine the efficiency of the amplifier. Each has its advantages and disadvantages. There are a number of different classes available in the market, but we are only the two most popular on the market today. Are Class AB and Class D. Ninety percent of the amplifiers can be divided into two categories. Class AB is the most popular. Offers a much better sound quality, but produces more heat than Class D. Class D is quickly becoming popular on the market, especially with the subwoofer amplifier. Provides a lower sound quality, but is much less heat and requires less space. Class D is used to power subwoofers. Most experts recommend that the Class D is for the subwoofer and class-AB power for the door speakers. Because our ears are less sensitive to lower frequencies, the lowest sound quality of Class D is not so audible.

Crossovers

Most amplifiers come with an integrated circuit in the junction. Crossovers block certain frequencies from the speaker foods. The two types of low pass and high pass. Junctions to low-pass only low frequencies pass, high pass crossings while only high frequencies pass. The frequency with which this happens in court may be in your amp. How can you? For example, if you have a subwoofer, you do not want your subwoofer to the production of medium and high frequencies, ie, a low-pass crossover, to ensure that the SUB is only producing low frequencies.

High-Level Inputs

For those who do not want to change your factory radio, you can still be a final stage, a condition requiring a high level of inputs. This allows the speakers to your factory radio to supply the signal to your amp.

RMS and peak power

Sometimes, the manufacturer also amplifiers. Both ratings are RMS and peak performance. RMS is generally known is that you should make when buying an amplifier. Often, only the RMS rating list. If only one classification, is usually the RMS On. The RMS rating is the amount of power an amplifier can be at a constant speed (full). The peak power is the amount of power an amplifier can demand for a short time. For example, if you listen to your music and suddenly a score of heavy blows, the amplifier peak power depends on the time because he was forced to draw more power to deal with this note.

This is our guide to buying a car amplifier. There are many different amplifiers on the market for all types of data to search. In this guide we have on the most important. Remember, first, how many channels you need to power and how much energy is required. Also, remember to make sure the device is compatible with the CEA will ensure that you are really all you pay.
