商务车改装步骤一：安装完以后，先检测整套系统

Business car step: after installation, the first set of detection system

1、 检查线路连接（最重要是检查功放的正负极是否接反）

1, check the line connection (the most important is the positive and negative pole power check whether the reverse)

2、 喇叭、功放等的牢固程度

2, a strong degree of the power amplifier, loudspeaker

商务车改装步骤二：给电容充电

Step two: business car to charge the capacitor

商务车改装步骤三：设置分频点 根据扬声器的需要设置分频点。

Step three: business car setting points frequency divider setting point according to the speaker needs.

不同扬声器具有不同的重放频率范围，根据这些特性来设置功放的分频点，如果主机有独立超低音信号输出，我们在低音功放选择全频信号就可以。

Different playback loudspeaker with different frequency range, to set the power amplifier according to the characteristics of the crossover point, if the host has independent subwoofer output, we choose the frequency signal in the bass amplifier can.

商务车改装步骤四：增益的调节

Step four: business car gain adjustment

1、 将主机和功放的增益调节到最小的位置。

Regulation 1, the host and the gain of the amplifier to the minimum position.

2、 设定好主机的新有功能（包括BAL、FAD、LOUND等）一般情况下都调零。

2, set up a host of new features (including BAL, FAD, LOUND) are generally zero.

3、 用一张以人声为主的CD作试音碟。

3, using a test disc with vocals based CD.

4、 逐渐调高主机的音量直到听见失真，再往回调低音量直至听不到失真，主机的音量就固定在此位置。

4, gradually increase the volume until the host to hear distortion, the volume can not hear until the callback distortion, the host volume is fixed in this position.

5、 逐渐增加功放的增益，直到你所期望的音量，注意不要产生失真。

5, gradually increase the gain of the amplifier, until your desired volume, do not produce distortion.

商务车改装步骤五：检测喇叭的相位，包括试听低音的正反相效果，（如果音量在增大的过程中低音变弱，就可肯定低频反相了）。

Step five: business car horn detection phase, including reverse effect audition bass, (if the volume in the process of increasing the bass is weak, you can certainly reverse the low frequency).

步骤六：汽车音响的功能基本调节 让顾客坐在驾驶座位上，将车门关紧

Step six: car audio function regulation for customers sitting in the driver's seat, the door shut

1、 选择适当的试音碟 来福的产品在音质上以清晰、层次感分明为优势，尤其适合重现大动态交响乐、流行歌曲（人声）、古典音乐等。在一套来福的汽车音响中我们很容易感受到中高频清晰的细节。如果在您安装的系统中有超重低音喇叭，那么您完全可以体会到什么叫有"Body"感的淳厚低音。厚实但决不拖泥带水。 注意：无论您采用什么样的试音碟，请不要将音量调得过大。

1, select the appropriate products to test on the quality, with a clear sense of hierarchy for the advantage, especially suitable for large dynamic reproduction symphony, pop songs, classical music (vocal). In a live car stereo, we can easily feel the high clear details. If you install the subwoofer in the system, so you can feel what is called a "Body" sense of strong bass. Thick but never do things sloppily. Note: whether you use what kind of test, please do not adjust the volume is too large.

2、 声场的定位 调节BAL、FAD选项，使顾客在车中能够体会到声场在车内前、后、左、右的定位，如果该机器具有S.P.S（车内聆听位置选择）功能，千万不要忘记给予演示。

2, BAL, FAD sound field positioning adjustment options, so that customers can feel the sound in the car before and after, left, right position in the car, if the machine has S.P.S (select the listening position inside the car), don't forget to give a demo.

3、 声音的处理 在声场定位功能演示后，我们可以进行各种声音处理操作，如BBE、SOUNDNESS、DSP声场模拟、环绕音效、L.P.S等。

3, the sound processing in the demonstration field positioning function, we can carry out various sound processing operations, such as BBE, SOUNDNESS, DSP, L.P.S surround sound field simulation, etc..

4、 调节高音的方向，利用高音的指向性特点来调节声音效果。

4, treble direction, using directional characteristics to adjust the sound effect of the treble.
