500 watts...boy thats some speaker, I've seen $3,000 speakers that can't handle that much power!
He's got to be joking, why would you want anybody to know your selling White Van Speakers. That would be like selling a used car and saying...yes, this car was totaled, but it's fine now, even though the right wheel is inside the wheel well 2" farther than the left and it drives down the road crooked.
