hey, i was just wondering about playing music at its loudest and the bass turned high, would this cause the bose speakers to lose their crystal clear sound and quality after years or possibly months?? or they will always work fine like the 1st day?

 

Like most everything else it will degrade after a while, if you blast it with the Bass turned up it may be sooner that someone playing at half the volume. However in the stock BOSE system if you turn the BASS up all the way and your volume up the BOSE system automatically adjust the BASS level so it is not distorted.
