How to install a car amplifier?

1:Look at the car host is the original model (most of the original models do not have an audio signal output interface, then you need to do it yourself to add a, or do not change, and in the speaker line to add a high to low as the signal source of the amplifier.) The mainframe, which has been modified, generally has an audio output port, and the signal line is directly connected to it.

2:Find an amplifier control line, amplifier connector for REM, to be positively charged (some hosts have amplifier control line, if not, connect an ACC at the ignition switch).

3:From the positive terminal of the battery to connect a special fuse for the amplifier, the line from the fuse out of the line to the amplifier's +B.

4:In the vicinity of the amplifier connected to the hitch (the hitch must be solid with the real), connected to the amplifier's GND.

5:Connected to the speakers, depending on what you use the amplifier, the four-way can be connected to four speakers, or two speakers and a subwoofer. and a subwoofer. The two-way then connect two speakers or a subwoofer. In fact, the installation of the amplifier is very delicate, this is just the basic connection, there are about the fuse selection, alignment, signal shielding, capacitors, audition and other tedious process needs to be completed slowly.

Extended information:

Normally a car amplifier to be used, the power connection part of the composition of the input line is:

1. B +: that is, the positive 12V, connected to the engine engine battery.

2. GND: that is, the amplifier's hitch wire, connected to the car body on the iron.

3. Amplifier power control line: generally connected to the +12v output of the audio host or the key start ACC line.
