Boost Your Power with a Car Amplifier

A car amplifier will give you a loud and clear sound on a consistent

basis. It will boost the power flowing from the receiver to the

speakers. In doing so, it will reduce the stress put on all the other

components of your car stereo system, including the receiver.

Choosing the right car amplifier is important. Your decision should

be based on five important features. Make sure you address them all !

The first item on the agenda is the number of channels. This will

depend on the number of speakers in your system. Two-channel amplifiers

will feed well two speakers or a single subwoofer. You will want to

consider a four-channel amplifier if you have any of the following

combinations :

¤ Four speakers

¤ Two subwoofers

¤ Two speakers and one subwoofer

Then you want to look at power. An amplifier with an output

two times the one of the receiver will give you enough added volume

with less distortion. Make sure the wattage of the amplifiers is

within the speaker’s range. Also, make sure your electrical system can

support the additional wattage.

An important feature to consider for your car amplifier is the

connection structure. Many factory-installed receivers only come

with speaker-level inputs that will require special adaptors.

This will normally work very well. However, you may experience some

distortion through the speakers. In that event, you may want to

consider a new CD/MP3/AM/FM receiver, depending on your budget and

sound requirements.

An amplifier normally includes a device to filter different

frequencies and minimize distortion. This is called a crossover.

Your amplifier should have one crossover for high-frequency notes

and another for low-frequencies.

We should discuss one last feature. Most car amplifiers can combine

the power of two channels into a single one. This is called bridging

and is used to boost the power of the amplifier. The downside to

this technique is to create some distortion and limiting the number

of available channels. Since the cost of a an amplifier is more

and more reasonable it might be wiser to buy a more powerful one !

Here you go ! You are hopefully better “connected” to the important

features to consider for your car amplifier ….. and more knowledge

means ….. more power …. to make the right buying decision.

Practical Tips for Choosing the Best Car Amplifier

You want to enjoy the best audio entertainment in your car. This is perfectly possible with the right car amplifier. There are numerous models to select from so you have to evaluate each model’s benefits and drawbacks. Here is some essential advice which you will need for making the right choice.

Determine the most suitable type of car amplifier for your sound system.

There are models which are designed to boost the signal sent to two, four, five or even six speakers. You should choose the number of channels based on your current system or on your plans for expanding this system. If you plan to upgrade, you should definitely go for a model with more channels.

You should know that there are two types of channels. The stereo ones deliver either a left or right-side signal while the mono ones provide both left and right audio. If you have a subwoofer, you should certainly consider a car amplifier with two or more stereo channels and one mono channel which will give you the super deep bass that you want to enjoy.

Evaluate the power of the device extremely carefully.

The technical capabilities of the device are among the most important factors which you should base your choice on. There are two types of power measures to watch out for. The root mean square power or RMS power measures the amount of continuous power which the device delivers to the speakers. The RMS power of the amplifier must match that of the speakers.

The other measure is the peak amplifier power. It indicates how much wattage the device is able to use for short and unexpected increases in sound. This number is always higher than the RMS power number. The higher it is the better the device will perform so that you can enjoy even better sound quality.

Look for capabilities and features, which match your needs precisely.

Since your stereo system has a built-in amplifier, you have to choose the additional one in line with the capabilities of the original unit. Take into account the amplifying power of the built-in unit and ensure that the additional one provides between 75% and 150% of the power limit of the speakers.

If you want to get super deep bass, you should go for a device with low-pass filter and built-in bass boost. That way, you will literally feel your heart pounding with the beat of the music. If you want trebles with amazing clarity coming out of your tweeter speakers, you should go for a device which features a high-pass filter. That way, you will protect the speakers and ensure that they will have a long useful life in addition to enjoying music even more.

Get all the accessories which you need for installing the device.

Most amplifiers designed to be used in cars do not come with all accessories which are necessary for their installation. That is why you should check what is included in the package and get the rest of the items separately. Alternatively, you can consider purchasing a complete car-wiring kit.

Finally, you should certainly consider buying a car amplifier from a brand, which has solid market performance and excellent reputation. That way, you will not have to worry about quality. Besides, you will get a warranty which is comprehensive and sufficiently long.

Features to Look Out for a High-Quality Audio Amplifier

When it comes to an audio or integrated amplifier there are a lot many things that can influence one’s choice. An audio amplifier is important equipment for those who want to amplify the low range audio waves or signals into a high range audio signal which can be heard through headphones or loudspeaker. For the first time buyers, specifications and several features of an integrated or a simple audio amplifier can be confusing, and thus one needs to be sure of the much-needed specifications which matters. Now, that one can make an informed and clear decision according to one’s needs and requirements, certain features are listed below which one needs to keep in mind while buying one.

Total Harmonic Distortion

One should check the total harmonic distortion and inter-modulation distortion level of the audio amplifier before buying. One amplifier may give any one kind of distortion only. Having a THD means the unwanted signals will be given out at the output due to the harmonics and IMD means that the unwanted signals are present at the input and interference occurs at the output due to other elements like diodes.

Output

The next important thing is the output power of the amplifier, which means the amount of electrical power it can supply to the output speakers without any kind of damage. One should check the nominal power labeled which will be the value of the continuous power that will be supplied without any kind of damage or distortion.

Frequency

The frequency response is the relational response between the input and output level of the signals. Always check that the frequency response is between the audible band that is in between 20 and 20,000 Hz to get the best quality of the output.

Sensitivity

The sensitivity of the amplifier refers to the feature that states the minimum input signal that is needed to cause a maximum level of the output signal from the amplifier. Having a sensitivity which it is too high or too low can cause a lot of distortion in the output signals. Lower the value greater the sensitivity mentioned of the amplifier.

Impedance

Impedance is important to find the voltage adaptation between the amplifier and the sound source and one can find different impedance for different sources of audio input. Amplifiers tend to have both output and input impedance, and one should look out for a higher input impedance to get the proper voltage sourcing.

Gain

Next thing to check is the gain of the amplifier. It is a source of signal power between the output and the input power of the amplifier which is denoted in the form of decibels.

Signal to Noise

In amplifiers the higher signal to noise ratio will always enhance the output quality. It depicts the difference between the noise level and output level of the amplifier and sound level. It is the magnitude difference which is specified in hertz. Also one should find an amplifier which can amplify various types of audio sources and channels to prevent the crosstalk.
