Choose amplifiers have tips gm tech2

Car audio as flow of the concert hall gm tech2  GuLv becomes a kind of enjoyment. Whether or not the car audio enthusiasts, in the face of these full of metallic simple sense equipment will be its unique magnetic deeply attracted. But perhaps for most people, how to choose and buy satisfaction of the audio equipment is a difficult problem.
Below we will introduce some amplifiers selection of some tips.
Determine the same benchmark amplifier power
Power is sound system is the most important parameter, said a sound system with load ability. This is also our when buy should be paid attention to in the first place. But if each manufacturer with different measurement datum to mark product performance, the lack of enough know it is difficult to make objective comparison. Power amplifier is also so, in view of the power amplifier logo should pay attention to the following three points:
Firstly, the battery voltage.
Car battery voltage is  gm tech2 often change, for the two kinds of common logo: 14.4 V / 100 w, 12 V / 100 w power amplifier are two different power description. Because of the car in the process of driving voltage basically in the 12 v or so, so in 12 v voltage condition the measured power value is more close to the truth. And with the constant voltage 12 v as the datum mark power amplifiers in reach more than 12 v can attain greater power.
Second, the harmonic distortion rate THD.
In comparison of the power amplifier continuous output power, should be in the same (or more close to) under THD value. Different THD value test out quality difference is very obvious, sometimes the identification of the maximum power is very high, but is likely to its distortion and noise is also very high. So in check maximum power at the same time should also pay attention to the identification of THD value.
Thirdly, frequency range.
Power amplifier of continuous power output should be in its actual use frequency range for detection. For the power amplifier, should ask the identification complete detection range, only mark a frequency power value doesn't make any sense.
In determining the same reference,volvo vida dice  we can to compare the power amplifier. Usually, in the choose and buy when sound system generally follow the principle of high power output. The greater the power amplifier output power, showing that they drive the speaker's ability is stronger also. The power amplifier should be greater than horn instructions power, if choose power partial small, in the long-term use of high power output, easy to burn out, still can bring about quality difference, distortion and the emergence of the fault.
High quality power amplifier should have the factors
Of course, only by high-power some text is not better able to understand amplifiers stand or fall. The high quality power amplifier must also it can respond quickly to the music signal peak, at the same time corresponding to strong heavy bass, and in low distortion/low noise condition can provide stable output. To meet these requirements, we must have the following:
