Nowadays, many car enthusiasts are very enthusiastic about car audio modification. With the increasing demand, it has further driven the development of the car audio modification industry in Chengdu. The correct connection of wire ports is crucial in the process of car audio modification, otherwise it will affect the correct use of the audio system. Therefore, the LED Bluetooth audio system will introduce common wire ports for car audio modification.

1. USB

USB is a serial port bus specification used to connect computer systems and external devices, such as recording interfaces and main control keyboards. Nowadays, the USB interface and SD card slot on most car models mainly support MP3 and WMA format audio files.

2. RCA

RCA is mostly used for signal transmission between sound sources and amplifier devices. If it is simply transmitting audio signals, a single RCA cable can only transmit signals from one channel, so generally, RCA cables used in audio systems are grouped together as one on the left and one on the right.

3. AUX

This port can transmit sound from both the left and right channels with just one plug, so it can be considered quite unique.
