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 reciever 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.
