I've just been told that the infotainmentsysteem of Kia does not have a connection for a subwoofer. Why is there no connection? Some people want to upgrade their sound quality and a high class subwoofer is perfect for in the car to improve the sound quality significantly. When I hear the term infotainmentsysteem, I think about a complete audio/navigation system, which will provide the possibilities to attach several devices and sound improvements. However, I've just been told that this infotainmentsysteem does not have any connection possibilities at all. Quite disappointing to be honest, whilst having one of the most complete and luxury cars in the A-segment, without having a possibility to connect a simple external Subwoofer. And because of the fact that this infotainmentsysteem does not have any connection possibilities, there is no other way to enhance the sound quality.
