In the audio field, in particular car audio, amplifiers commonly referred to as sound power cars. The use of amplifiers in car audio systems aimed to strengthen sound audio signal originating from the main source or a head unit which will then be channeled into an audio speaker sound. So the charge amplifier receives an audio signal sound from the source and process it for car audio signal has more power and strength so that the car speakers capable of removing the maximum sound due to get additional power is needed in removing the audio sound waves.
Amplifiers for car audio use, generally known as multi-channel and monoblock type of audio sound. Multi-channel amplifier is generally used to strengthen the signal output of car audio in the form of electric currents into sound car speaker (Tweeter, Midrange, Midbass or Coaxial speakers), while for the type of car sound monoblock, used specifically to strengthen the signal sound cars that will be channeled to Subwoofer who desperately need a big power.
In particular, amplifiers sound the car is also known by some kind of amplifier, the type of audio sound class A, B, AB, D, Hybrid, Tube, car sound cheap and each type has its own character, the power output is different, namely:
Class A: Having a car the best sound quality to produce quality sound. Prices for cars sound of this type are generally very expensive, but even then it depends on the brand and there are also sound cheap.
Class B: No quick heat and not wasteful of energy, resulting in sound car audio is pretty good.
Class AB: It is the sound the car’s most widely used by cars audio players, can be more efficient and flexible for use in cars sound system and have better quality than class B.
Class D: This type of audio cars are most often used to drive a subwoofer and used to the concept of SPL (Sound Pressure Level) because the cars audio class D amplifiers have a large and capable Watt loaded to below 1 ohm, so that they can produce more bass sound dynamic and usually it is the type of class D monoblock amplifier.
Hybrid: This type of sound amplifier is a cheap car that uses transistors and electronic components are also tube, but still can be held by audio cheap prices that are still affordable.
With the difference in quality, character and components of each type of audio amplifiers cheap car, proving that quality amplifier can also determine the character and quality of sound produced in cheap car audio systems.
For that before purchasing an amplifier should be much to be considered in order not one chose, here are some tips on choosing a cheap sound amplifier:
1. Select an amplifier with RMS value (Watt) are large and its THD is small.
2. Design and material quality also remains to be addressed.
3. Adjust power / RMS amplifier with the speaker needs to be used.
Tip: Do not let a cheap audio amplifier is not used within a period of time, because it can cause damage electronic components.
