Car audio systems are becoming increasingly popular as time goes on, simply because technology has provided people with a way to listen to their car with tremendous power and quality. Most people install a power amplifier in the speaker system of their subwoofer. However, if you are a bass freak who loves superior sound quality, another good thing is to have the preamplifier.
Many car owners rely on a preamplifier to improve the quality and power of the sound of their subwoofer speaker system. It is not always necessary but is becoming increasingly popular in car radio systems. The preamplifier is great if you want to add a brighter bass with a lower distortion level.
What is a preamplifier and what does it do?
The main function of the preamplifier in the subwoofer speaker system is to prepare the signal from the power amplifier. There are various types of preamplifiers, such as USB, tube and phono preamplifiers. However, the preamplifier that you would use in your car's subwoofer speaker system would be a stereo preamplifier.
The preamplifier is used to improve the overall sound quality in the audio system of a car. An important thing to keep in mind is that the preamplifier only provides voltage, no power. The power amplifier is the part that supplies the power, so you can not have one without the other. Think of it as a team where the preamplifier throws the ball to the power amplifier and the power amplifier shoots the target.
In the stereo system of your car, the preamplifier is the "middle man" for the audio input "stereo" and the power amplifier. When you switch on your stereo system, an audio signal is sent to your pre-amplifier. The preamplifier then takes that signal and adjusts it when it is too low. Then it sends the level signal to the power amp and the power amplifier adds the gain or power needed to get the best signal to your speakers.
Some stereo systems are equipped with both a pre-amplifier and a combined amplifier. There is a debate about the quality of this method among serious audiophiles. It is safe to say that if you have the power amplifier and preamplifier in separate parts of your car radio system, you do not have to compromise on sound quality. The preamplifier in your car's subwoofer speaker system will also be a control panel. From here you can manage connections, levels, volume, etc.
Preamplifiers are a great piece to have when you install a subwoofer speaker system in your car. They add the overall quality, power and sound to your car's audio system. Some people choose to leave the preamplifier completely, but if you want the best quality, you want to be sure that you record it.
