The obvious reason is that i play my music too loud.
But, it's strange. My rear speakers are sony xplod dual channel. I have my speakers set up so that the right side doesn't play as loud as the left (My front right speaker would pop insanely fast because it's stock).

Same speakers in the rear and the right doesn't even play as loud as the left. But, it's the right that pops!
My rear right speaker has popped before, but i just thought it was because i played my music too loud and the old speaker couldn't handle it.

Any crazy ideas as to why? ? Or am I just being a crazy person playing my music too loud? ?
