Oh, sorry for that confusion, I really just was talking about the cost of the "solution", when the original question in the thread was adding an aftermarket amp. Yes, of course when you add the cost of the amp and summing device (that I guess is necessary) it does add up to more. Sure, add the cleansweep, summing device and a good amp and you're definately pushing a grand. If anyone really wants a final tally, I'd be pleased to provide it. It figures I'd see your option after I got my CTT done last week. I'd like to think the shops just weren't aware of your technical solution, I know my guy wasn't.
