connecting mono amps to pre amp


Newbie here. I'm 56 and this past year and a half, I've  gotten back into 2 channel. Various amps/pre amps and receivers. I would like to know how to properly connect (2) Mcintosh 2120's to a Mcintosh MA 6100. Have several mac pieces as well as others. But seems Mac is kind of like BMW/Mercedes -European cars with the fact of over engineering or over features, for a lack of better words. Can someone shed some light here with regards to the MONO bloc connection on these? Thank You in advance!!

Go to the rear of your 6100 and you should see 2 small U shaped pieces of metal. Pull them out. Plug the left and right interconnects for the amps into the 2 rca jacks that are labeled preamp. 
Al is right. I thought you had 2 mono amps. It never occured to me that you wanted to bridge 2 stereo amps.
Not to confuse you, but since you already own both amps, you may want to try a vertical biamp. (I'm assuming your speakers have 2 pairs of binding posts). For the most part, people feel that bridging a stereo amp degrades sound quality. How much will vary from system to system. A vertical biamp will allow you to use both amps unbridged and avoid any power differences that usually come up with horizontal biamping.

If you want more info, have a look at this.

Personally, I think APJ is the best reference on high end audio ever written. There's an incredable amount of useful information in it.  
The people at Richard Grey said their stuff was better. Who do I believe?

By the way, does your unit protect against a direct lightning strike? If it does, how?
