Facts of Car Audio Amplifier

Amplifier can be considered as an energy generating system for a system sound. Each audio system would require an amplifier.Although the head unit you already have a built-in amplifier, but when you use an amplifier addition, the results of his voice would rise dramatically. Amplifier is a sounding speakers. When the amplifier head unit you sounded weak, it is because energy is not enough to ring the speaker to get optimal sound. That's why many people add amplifiers addition, especially for sound sub-woofer. When installing an amplifier, there are some things to consider, among others, always use a fuse that is placed adjacent to the battery. Give a protective layer on the positive wire from the battery to the amplifier, because the whole body of the car you are negative. When the cable is not well protected and there are parts that peeled off, you may cause a short circuit occurs and even fire. RCA cable from the head unit to the amplifier must be set on track for not having contact with electrical lines to prevent cars from Storing or noise. Amplifier I say such a generator energy, because it's the way it works is to receive signals from the head unit, then enlarged without adding or reducing the quality of the original. That is why the amplifier is often referred to as power, which means power. Energy received is in the form of 12 volts DC, then by converted into AC power supply and applied to the speaker. Positive pole will drive the speakers and the negative pole will attract speakers, then timbulah sound.
Amplifier power supply using MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) are able to work more efficiently, can be invited to play at a low impedance and heat resistant. Impedance is the resistance of a speaker, expressed in units of ohms. Usually the speakers car using a standard 4 ohms, while the speaker 8 ohm impedance house. When the amplifier to work at 2 ohms, he will issue a power of two times greater than when working at 4 ohms. A value of 2 ohm can we get from combining the twospeakers berimpedansi 4 ohms with a parallel formation, meaning that the positive pole coupled with the positive and negative poles are connected by a negative and a new terminal connected to an amplifier, be a 2 ohm impedance. For example if on the 4 ohm power an amplifier out 50 watts, then when at 2 ohms would produce 100 watts, and when one ohm will produce 200 watts.
There are things to consider in selecting an amplifier for car audio, which was to determine the number of channels required before deciding to buy an amplifier. Amplifier for car audio four channel example, you can use for a pair of speakers front and a pair of speakers behind. Other formations, you can set to ring thespeaker front, and two more channels in the bridge to ring a subwoofer. Can also fourth in the bridge channel into two channels to ring a pair of subwoofers. Or a more complicated again, the amplifier is played with six-channel active crossover system to ring a 3 way system consisting of a pair of tweeters, a pair of midrange and a pair of midbas. So you think about it what kind of system you want to make, determine the number of channels needed, buy new amplifiers are needed.
