When wiring, try to use the audio cable with the same thickness or a little thicker, but if the connected audio cable is not connected correctly, it will seriously increase the line resistance and increase the loss of sound quality. It is recommended to buy a longer one.

The speaker cable is used to connect the power amplifier and the speaker, in which the current signal is much larger than the video cable and audio cable mentioned above. Because of the large signal amplitude, such cables often have no shielding layer. For this kind of wire, the key is to reduce its resistance, because the output impedance of modern power amplifier is very low, so the requirements for speaker cables are also improved, such as using large cross-sectional area or stranded wire.
