How to install the power amplifier and how to install the car power amplifier?

Wiring: 1. The signal input is connected to the two lotus seats with low level.

2. Two groups of horns, one on the left and one on the left.

3. The positive end of the power supply is connected to the positive power, the ground wire is connected to the negative pole of the power supply, and the control termination is connected to the control output of the CD or the vehicle host, and it is directly connected to +12V when using at home.

The installation is very simple, the audio source (computer, DVD player, etc.) - power amplifier --- speaker, and the middle cable is connected.

How to install the Japanese Onkyo amplifier.

Wiring method: In parta, connect acc, b+, ill to +12v, gnd to -12v, and everything else is empty;

In partb, four "4 and 5W" speakers are connected accordingly.

The maximum total power consumption of the measured power supply is about 60W, and the average power is 45W;

The maximum measured power of each speaker is about 5W, and the average power is 4W;

No load (remove the four horns or turn the volume knob to the minimum, i.e. be in a silent state), the power is W.

1. Car power amplifier refers to the car audio power amplifier, which is a power amplification device added to the middle of the speaker input and the sound source volt output; 2. Before installing the power amplifier, it is necessary to carefully check the speaker parameters (radiated sound intensity, rated power, input form, etc.), audio source output parameters (output power, interface form, attenuation, impedance, etc.), and match the signal parameters and power parameters of the power amplifier itself before it can be installed.

It is more troublesome to install power amplifiers in automobiles, because the country does not stipulate a unified standard, and the output socket of the automobile amplifier (it is the power cord, signal input, and output line is in the form of a socket) and the car plug need to adjust the plug position according to the drawing, and then plug in.

1. Select high power output. In a sound system, the greater the output power of the main unit or amplifier, the greater the linear range of audio they can control, and the less powerful the ability to drive the speakers;

2. Matching is more important than equipment. Whether it is a large-scale system or the original car system, how to skillfully match is the key, so the owner in the selection of equipment, to have a good communication and exchange with the audio modification technician, to the personal preferences, modification requirements and economic affordability to tell the technician, so that according to the performance of each product for the best matching, design a cost-effective and reasonable modification program;

3. Gradual upgrading. Modify the audio to consider the long-term of Minghu, if the picture is cheap for a while, some parts "will" be used, once further upgraded in the future, it will be found that the things installed before have almost become a pile of waste, but cause waste.

How to install a car power amplifier? Installation method of vehicle power amplifier:

1. The car power amplifier refers to the car audio power amplifier, which is a power amplification device that adds input vertical margin type and audio output in the middle of the speaker;

2.Before installing the power amplifier, it is necessary to carefully check the speaker parameters (radiated sound intensity, power rating, input form, etc.). ) and sound source output parameters (output power, interface form, attenuation, impedance, etc.) , and only if they match the signal parameters and power parameters of the power amplifier itself, can the power amplifier be installed. When the parameters do not match, the sound quality, sound effect, and volume will all be affected. When the imbalance is severe, noisy and harsh current noise and interference noise will occur.

3.As an intermediate stage of the signal, the power amplifier can be cascaded, i.e., multiple power amplifiers are connected in series. The car audio and video device Yuchai usually integrates its own first-level power amplifier, and it also needs to be matched step by step when it is cascaded.

4.A power amplifier is a high-powering appliance in a car. When installing, it is necessary to consider whether the load capacity of the battery and generator is sufficient.

When the engine is turned off and the generator is not working, do not use the battery for a long time to make the audio work. This will cause battery feeding, affect the use of electrical equipment such as ignition, and shorten battery life.
