In the field of Car Audio (Car Audio), the amplifier also known as power. The use of amplifiers in Car Audio system aims to strengthen the voice signal coming from the main source or a head unit which will then be channeled to the speakers. So the charge amplifier receives a signal from the sound source and sound signal processing in order to have more power and strength so that speakers can make a sound for a maximum intake of energy required to remove the sound waves.

Amplifier for use of Car Audio, generally known as multi-channel type and monoblock. Multi-channel amplifier is commonly used to strengthen the output (output) Audio Sound signals in the form of electrical current to the speaker (Tweeter, Midrange, Midbass speakers or Coaxial), while for the type of monoblock, used specifically to enhance the signal to be channeled to the subwoofer are very requires large resources (Audio Sound).

While in particular, also known as the amplification some kind of amplifier (Audio Sound), the type of class (Class) A, B, AB, D, Hybrid, Tube (tube) and each type has a character, the power output of different , namely:

Class A: Having the best quality to produce quality sound, but very wasteful of energy and heat faster. Prices for this type are generally very expensive.

Class B: No quick heat and wastes no energy, but has a quality in producing good sound.

Class AB: It is the most widely used by car audio players, because it is a combination of amplifier class A and B, which can be more efficient and flexible for use in car audio systems and have better quality than class B.

Class D: This species is the most widely used to drive a subwoofer and used to the concept of SPL (Sound Pressure Level) for Class D amplifiers have a power (Watt) are large and can be burdened to below 1 Ohm, so as to produce sound more dynamic bass and usually kind of class D monoblock amplifier that is.

Hybrid: This type of amplifier is an electronic component using transistors and tubes (tubes). Merging these two components make this type of amplifiers capable of producing sound quality of character is thick with good tonal accuracy as full-tube amplifiers, but still be owned by a still affordable price.

Tube (Tube): car audio enthusiast circles recognize this type of amplifier can produce better-quality sound with a vowel sound character more natural, not thick and stiff / dry, but the type of tube amplifiers, generally have a very expensive price.

With the difference in quality, character and components of each type of amplifier, proving that the quality of the amplifier can also determine the character and quality of the sound in a sound car audio system. For that before buying the amplifier must be many who consider that not one choose, here are some tips on choosing amplifier (Audio Cars):

1. Select amplifier with the RMS (watts) the large and small THD.
2. The design and materials quality still must be considered also.
3. Adjust power / RMS amplifier with speakers need to be used. Power amplifier must adhere to or greater than the required speakers, because if the power is smaller than the needs of speakers can cause damage to the speakers used, because of the ’signal clipping’.
4. Select brand amplifier that has an official warranty from the brand holders
5. Look for information from various media or check with the installer car audio amplifier trusted before buying.
