Do you have the original box and papers that came with the amp ? I know you said you dont have the birthsheet but I wasnt sure if you still had the owners manual and original box for it i'm not sure if those came with remote gains either. But im currently installing a system for a friend and the ideal amp for it is a tantrum 1200.1 so this may save him a lil $. I'll go ahead and offer 285 shipped and let him know about it do you accept paypal ?
