Product introduction: (audio filter)

The use of high-quality audio cables can eliminate car audio noise, or other high and low frequency clutter noises, allowing you to listen to all kinds of wonderful music comfortably.    

An example of the number of audio filters used:

Example 1: 1 audio cable (i.e. 2 audio plugs) from the host -- 1 audio filter -- 2 one-point two-wire (turned into 4 audio heads) -- enter four-way amplifiers;

Example 2: 2 audio lines (i.e. 4 audio plugs) come out of the host -- 2 audio filters -- and enter four amplifiers.

How to connect the power filter:

Both ends of my car are grounded. There are two 12V wires on the car, one red and one black.The machine is also one red and one black?

Answer: There is only one way to connect the power filter. There are three wires on the power filter, one red, one blue and one black; one red and one blue are 12V output and input, and the other black wire can be connected to the car shell.Iron will do.

Question: Are the black lines on the 12V black line and the black line on the car receiving the black line of the filter?

Answer: As long as the black of the filter is grounded, it is fine.

Question: It means that all the black wires can be connected to one piece, and the main point is to connect the input to the red and the output to the yellow, right?

Answer: It can be said that, but the way we connect it here is that the black wire is generally connected to the nearest car shell (metal part).

Q: The problem is that there are no metal parts in the recent car shells?

Answer: It can also be connected to one of the black wires you just mentioned.
