Someone prove me wrong and tell me this is not the 6k Bass Clef, which I happen to own, before branding by Crescendo. I have already learned that MANY car audio products are simply items produced and sold in bulk, in and from china. I am sure they have non-compete clauses of some kind in their contracts when they buy in bulk, which these chinese sellers always find a way to skate around.
