How to upgrade the Roewe i5 from two-channel to four-channel audio?
2 Answers
The method to upgrade the Roewe i5 from two-channel to four-channel audio is: You need to reposition the wiring behind the car audio bridge. Taking the 2021 Roewe i5 1.5L Manual Platinum Edition as an example: The manufacturer of this car is SAIC Motor, classified as a compact car with a naturally aspirated engine. The car's dimensions are 4607mm in length, 1818mm in width, and 1489mm in height, with a wheelbase of 2680mm. It is a 4-door, 5-seater sedan with a 5-speed manual transmission and a top speed of 185 km/h. The 2021 Roewe i5 1.5L Manual Platinum Edition features ventilated disc front brakes, disc rear brakes, and a handbrake parking brake system.
Last year, I also upgraded my Roewe i5 to a four-channel audio system, and the sound quality immediately became much fuller, like having a mini concert in the car. The specific steps were: first, install two additional speakers in the rear doors or behind the seats, as the original car only had two speakers in the front doors—a two-channel system with only stereo input and output. You need to buy speakers compatible with the original car system, such as those with matching power, and then check if the head unit can support four-channel output. For my own car, I used a small amplifier that supports high-level input to drive the rear speakers. When wiring, pay attention to the connections of the power and signal wires—don’t cut the original wires directly; using plug-and-play connectors is the safest. I bought a set of tools and spent some time figuring it out, working on it all afternoon before finally getting it done. The sound quality improved, with richer bass details, but the modification cost about 800 RMB. You also need to consider the wiring layout to avoid affecting the door seals, otherwise rainwater could seep in and cause big trouble. I highly recommend this small upgrade for music-loving car owners—spending a little money can bring the joy of surround sound.
