You are a cheap ***, this is why you bought a refurb item. You got a 90 day warranty from the date of purchase. You had a problem, they replaced the sub. You still have a 90 day warranty from the original date of purchase.
You seem to think that because the rep told you that because it was a new model, that you are entitled to the 1 year warranty. Did you also tell the rep that you had bought refurbs with a 90 day warranty? Probably not, you are a skid and are in this for yourself only. Buy one from a store and then swap it for the bad one, take it back and get a refund? You are a scamming POS bud, that is all there is to it. This is called fraud FYI and had you done it in my store I would have kicked your a$$ to the curb. Dude, call the kicker rep again so that you can believe what he tells you. When the Kicker rep tells you to "go eat a dick", I guess it means that you should.
