Upgraded my front stage amp to a an Arc Audio FD4150 to match the other two. This one was bridged and powered a set of Boston Z6s. Includes amp. box, all paper work, and bass boost knob. Notice that the ground screw has been replaced. Selling this one will supply the cash for a new HO alternator. No feedback here, but 100% positive on ebay under Surfjimc. $400 obo
