Modification Car Audio

There are three car audio device that can determine the sound quality of these audio and these should be known by the owner of the car. As for the audio device is the Equalizer (EQ), Pre-Amplifier (pre-amp) and Digital Processor

Equalizer (EQ)
This device has a function to set (adjust) the frequency of the sound to be flat. Almost all types of head units have generally been the equalizer feature, however, generally only have to 3 or 5 band EQ, so that the tuning process becomes limited.

Meanwhile, if using a separate equalizer device, then the installer can get more leverage in the process of tuning, because the separate EQ can have more than 10 band EQ can be adjusted, alhasilnya sound frequency can be more regular and evenly so that it can be heard with good quality in car. For that much fitter who apply separate EQ product.

Pre-Amplifier (pre-amp)
This one device has a function to strengthen the signal from the head unit to the amplifier. Most pre-amps used in audio systems wing SPL (Sound Pressure Level). This is because the settings are very easy to be able to quickly change the signal strength from the head unit to the amplifier, so the sound is high or low could be stronger or weaker adjust quickly at any time.

Digital Processor
Digital Processor or better known as the processor is a device which in it already has a function as an equalizer, crossover (X-over) and various other fiur for tuning the sound of a car audio system. The existence of time correction feature is very important for the system of wing SQ (Sound Quality). Due to the processor, the process of tuning the sound quality ranging from color, clarity, linearity, attack-decay to the sound staging and imaging are all important points that must be obtained in the flow of SQ can be adjusted and shaped with a maximum.

Currently, several types of head unit also has a built-in processor and automatic equalizer features and x-over-active too, only has a limited ability, so many car audio enthusiast SQ wing using the additional processor, for audio system capable of a sound that very quality that meets the point of flow SQ.
