The use of signal amplifiers to modify the audio host is poorly solved. "My car modified audio is changed to the host, the radio effect is not as good as before", the main performance is:
1. The radio is not clear and the noise is very loud.
2. Many of the stations that were previously received can't be received now.
The reason for the above situation is that many cars have abandoned the external antenna for the sake of the overall shape, but adopted a new type of windshield printed antenna. The ability of the antenna to receive signals is worse than that of the external antenna. In order to solve this problem, the manufacturer has set up a "signal amplifier" at the receiving end of the antenna to improve the sensitivity of the radio. This antenna amplifier requires power to work. When the modified audio is changed to the host, many refitting personnel do not understand this, and there is no power supply connected to the "signal amplifier", resulting in poor radio reception.
The following is a solution we have summarized about poor radio reception after changing the host:
First, some Japanese cars (such as Yuda), the original car host behind a dedicated antenna signal amplifier power supply line. For these models, it is OK to directly connect a blue line (antenna start line) in the new host power line group to this line when changing the host. The operation is relatively simple.
Second, many European models (such as Volkswagen) do not have a dedicated antenna signal amplifier power cord, but are shared with the core cable in the antenna coaxial cable. For this type of vehicle, you can not directly connect the blue wire in the power cable set of the new host directly to the core wire of the antenna coaxial cable (the host may smoke if it is connected directly...). The correct way is as follows:
1. Cut the antenna cable and peel off the shield and core of the cables at both ends.
2. Make a small change to the antenna. A small ceramic capacitor labeled "103" (0.01 UF, the size of this capacitor is not strictly required, from 0.001 to 0.1 UF) is stringed between the two coaxial cable cores cut at both ends. . Reserve a terminal for use at the end of the external antenna. The shield copper wires at both ends are still directly connected together. This is done.
3. After processing the antenna, connect the blue line (antenna start line) in the power line group of the new host to the reserved connector in the previous step, wrap it with insulating tape, and insert it into the host. You're done.
Is it very simple? If you have this phenomenon after modifying your car, try it now! !
Note: This method is not available for all cars. Only those cars with antenna signal amplifiers are effective. Not suitable for vehicles with external antennas or without antenna signal amplifiers.
