I want to sell my 40.1 when it returns from the shop. I spoke with Nick at IA and he said that it failed due to low voltage and excessive vibration. I played it too long with the car switched off and blew the driver and output stages. Repairs are going to be around $450.00 so I'd rather just go ahead and sell it and buy me something new with a warranty this time. So if anyone wants it i'll take $775.00 shipped to you and it will be ready next Friday per Nick Wright. Price will be pretty firm because he's basically building a new amp replacing all 24 mosfets, driver board, and output board.
If price is too high, I'll entertain offers but no low balling.
P.S. If you want it, I can have it shipped directly to you straight from the shop.
