Amplifier - Car Amplifiers - Information You Should not Be Without

An amplifier takes the signal from the source and make it bigger. This makes the sound louder. The hard part is to amplify the signal without adding distortion. Amplifier must have a power supply strong enough to make them run and had to save quite a while to give all the transients in music.
How they work
A radio cassette or CD player produces a maximum of about nine real watts into four main speakers will be given power from the electrical system of the car. So what if you want more than nine real watts to power each speaker you obviously need an amplifier. Amplifiers provide more power that allows you to play your music louder. Amplifier also improves the sound quality of music at all volume levels.
Car Amplifier Features
Here are some important facts you should be aware of if you want to choose a right amplifier ...
o Bridging the amplifier is very versatile because it can be used in different system configurations. The amplifier can be used to power one two three or four speakers.
o Speaker level input is the only way you can get a signal amplifier if your radio does not have RCA-type output jack.
o Preamp output is very useful when creating a multi-amplifier system because they allow un-amplified signal to pass from one to another amplifier.
o Remote control available in some bass amplifier that has a port for adding optional control buttons. It varies the amount of power going to the subwoofer driven by an amplifier.
o High-pass filter and low-pass filter crossover gives you the flexibility to remove the frequencies you do not want to send to the speakers powered by an amplifier.
o increase the Bass available in multiple amplifiers. It allows you to significantly increase the bass up to dB through the circuit.
An amplifier can have one production line or as many as eight channels. The most common amplifiers are two and four channel models but mono amplifier is also becoming popular.
