: X3 2004 Sound System Upgrade

I have just recieved my new 2004 X3! Now I want to add more punch to the system without voiding any warranties. Is there a way to add a sub or more punch to the premium system with going overboard and freaking out BMW. :rolleyes:

Not really. Any modifications to the wiring allows the dealer to void your warranty for the components you modified (i.e. the stereo system). If you have a good relationship with your dealer you might be fine, but they have the absolute right to void your warranty on anything you modify.
