A dealer's primary obligation must be to his customers. In this case he should be communicating diligently with ARC to quickly resolve the issue without you needing to be involved. A dealer deserves to make a fair profit on the sale, and as part of that implicit agreement he has to be there for you if and when such problems occur, effectively taking ownership of your problem. If the dealer repeatedly ignores your requests or is very slow responding, your options are (1) let ARC know of your dissatisfaction with the dealer, (2) do what you have been doing and get it repaired by an authorized ARC service technician under warranty, and (3) sell the amps after they are repaired and move on to something else less troublesome.
This is not to say that instant response is due, just that weeks or months shouldn't pass before you have your amps back up and running.
Good luck and listening.
