Seems you bought the service plan when u purchased your subs correct? Now, this is what you do, like everyone else has said, blow the fuck out of the subs..go to customer service, tell them blah blah i have the service plan, my shit blew... I'm not sure if U.S bestbuy policy is the same..but anytime a speaker is blown, you get a replacement right away, given that you bought the plan (or unless u can bitch real good without the plan)... so anyways..pick up the clearance subs, buy service plan on them AGAIN..wait till 6 months..blow them the fuck up..and be like GIMME NEW ONES..now, since you said they're clearance, meaning new models will come out eventually, they will have to replace it with the newer model, they cannot give anything worse..it must be better or of equal value..
