There is no such thing as too much. There is however such a thing as too few. What you want is four. When using four they can be smaller, placement is a lot easier, and the resulting bass is so much smoother and real than two you will find it hard to believe.
You can connect three subs easily to your Naim- one each to the pre-out, plus one to the sub out. Don't worry about L/R, it does not matter with subs. Then you can add more, either daisy chain off one of the subs, or use a Y-adaptor. Off of what does not matter.
Another solution, right now the Dayton SA1000 amp and subs are on sale at Parts Express. One amp, four subs. Killer deal. What I did.
