Hi All,

This might have been asked before but just posting again, I have 66 plate x3 it comes with HK sound system how the system sounds really flat. I checked to see if the Sub where integrated under the seat however it seem that they are not present. Any one else be able to shed some light on this. I have 2 other BMW all with HK 65 plate 535d and 66 plate X1 and both sound great with the heavy bass.

Any help be much appreciate

Kinds regards
