What is overkill for Vandersteens?

Hi, I recently came into 2 McIntosh mc2500 amps, and I just bought a pair of Vandersteen 3a's. I was going to sell one of the amps, but should I just keep them and run them mono, or is that just ridiculous. How much power do most 3a owner use? I know I can put them in and listen, but they are heavy, and I've already hurt my back, and my 4 year old is no help. It would also bring up other issues (ie. another power cord, explaining to my wife where the chair went to?) I would rather not have to deal with unless everyone tells me I have to do it.

Thanks,
Mike
