Brand new, never installed Arc Audio KS 500.1 amp. I bought this for the X but never used it. Great amp for the X5 application because of it's compact size. Can easily be hidden. Purchased from a factory authorized retailer so warranty is still intact. Willing to ship. Original cost $499. Selling for $350.
