do you have to change or add an amplifier or just pop out the speakers? I have the upgraded sound for my x5 3.0
Thanks.
I'm not so sure about not needing to change the amp. Other persons have been told that crossover problems may require one to change the amp. Apparently the crossover specific to the factory speakers resides in the factory amp. If your drop-ins don't use the same crossover frequencies, you may have compatibility probs.
