Even if you keep the OEM navigation system, it is possible to add a subwoofer.
In practice, you would extract the audio signal from the OEM navigation unit and connect it to a subwoofer amplifier, so you can reinforce the bass without replacing the head unit with an aftermarket one. This is an easy option for those who want to add more sound thickness and stability without significantly changing the OEM look or ease of use.
Especially with OEM audio, the overall balance may not be bad, but the bass alone can sometimes feel a little lacking. Adding a subwoofer gives the impression that, rather than making things unnecessarily boomy, it creates a foundation for the entire music and makes it easier to listen to. Vocals and instruments also tend not to sound as thin, so you should notice the difference even during everyday commuting or driving.
However, depending on the vehicle model and the configuration of the OEM system, the required installation method and parts used may vary. Also, guidance may differ depending on whether there is an OEM amplifier and the specifications of the existing audio system, so for accuracy, we will provide instructions after confirming your vehicle’s specifications.
How much bass you want to add and how much you want to use the cargo area will also affect your choice. If you’re unsure, it’s helpful to organize your thoughts based on what kind of finish you want while keeping and using the OEM navigation system.
