Is there a reserved space for rear door speakers in the BYD Song?

BYD Song rear door speakers are not pre-installed. If you want to add an amplifier, you can simply pull out the wires. If not, you will need to route the wiring from the inner footboard to the central console, as the central console does not have pre-installed connectors for rear door speakers. Car audio (autoaudio) is a playback device installed to alleviate the monotony of travel for drivers and passengers. Relevant information about car audio is as follows: 1. The earliest used was the car AM radio, later AM/FM radios, tape players, evolving to CD players and compatible DCC, DAT digital audio. 2. Car audio mainly consists of three parts: the head unit, speakers, and amplifier.

I've specialized in studying the BYD Song's audio system, and indeed there are pre-wired speaker positions and wiring harness interfaces on the rear doors. Last time when helping a friend with the modification, after removing the door panel, I saw the standard plug left empty there. There might be slight differences between different year versions, for example, the 2022 model has the plug at the bottom inside the door panel, while the 2023 model moved it to the top. But overall, BYD pays great attention to expandability, basically keeping the wiring intact. When installing by yourself, pay attention to: it's best to buy speakers with original factory dimensions, coaxial speakers around 25W are the most suitable; test the voltage before wiring to prevent short circuits; after modification, remember to adjust the audio source settings to enable the rear channels. Avoid working on humid days, as the door panel clips are prone to damage. The total cost can be settled with a few hundred yuan, and the rear seat music experience is directly doubled.

As a frequent visitor to audio shops, I can definitively say that the BYD Song has pre-wired speaker locations in the rear doors, though the base model doesn't come with speakers installed. Last month, I just upgraded my own car - there's a blue connector on the inner door panel specifically reserved for rear speakers, with wiring already routed to the back of the head unit. I recommend sourcing used OEM parts as the easiest solution; a pair of factory speakers costs around a hundred yuan online. During installation, don't forget to check the sound insulation - some owners have reported resonance issues that can be fixed by adding damping sheets. Route the wiring through waterproof corrugated tubing and secure it near the door hinges with cable ties. Keep aftermarket speaker power below 30W as the stock head unit drives them perfectly; adding an amplifier just complicates things. The most noticeable improvement comes when listening to live concert recordings - the soundstage and envelopment improve dramatically.

My Song (BYD model) is the base trim, and the lack of rear door speakers had been bothering me for a long time. After removing the interior panel, I discovered complete wiring harness connectors neatly tucked inside. I bought a pair of coaxial speakers and installed them myself—just plug and play. Be careful with the door panel clips as they break easily; replacement parts cost just a few cents on Taobao. After the upgrade, vocals in pop music sound more three-dimensional, and my kids in the back seat say storytelling audio is much clearer now. Total cost was under 200 RMB, saving thousands compared to the factory premium audio option. Most car wash shops can handle this job nowadays, finishing in about half an hour. If there's rattling from the door panel, it might be due to uneven speaker installation.

With a decade of experience in vehicle circuit research, the rear door speaker wiring preparation in the BYD Song is truly well-executed. The door panel comes pre-installed with a standard ISO connector, featuring adequate wire gauge and foolproof design. The modification process is straightforward with just six steps: remove the door panel, unscrew the bolts, connect the speaker, reattach the waterproof membrane, test the phase, and reassemble the interior trim. It's recommended to use speakers with 89dB sensitivity, as the stock head unit can drive them effectively. After modification, remember to adjust the equalizer by shifting the sound field center 20% rearward for optimal performance. I've seen people install flashy speakers with LED rings, but the nighttime reflections can interfere with the rearview mirror. From a practical standpoint, standard wool cone speakers are sufficient, delivering warm and pleasant sound quality.

During the last maintenance, I specifically asked the 4S technician and confirmed that all Song models have pre-wired rear door audio harnesses. The base models come with plastic covers sealing the ports, which can be removed for installation. Pay attention to three points when doing DIY modifications: First, choose anti-magnetic speakers to avoid interference with the window motors. Second, conduct a waterproof test after installation—pour half a cup of water onto the door panel to check for leaks. Third, avoid over-tightening screws to prevent diaphragm deformation. The most surprising improvement after the modification is the clarity of navigation voice prompts, which were often unclear in the rear seats before. In terms of cost, domestic brands like YinDi or HiVi offer decent speakers at around 100 RMB, providing adequate sound quality. Remember to clean the door panel drainage holes weekly to prevent rainwater from damaging the speakers.
