Welcome to the forum!
Unless you have 2 main outs on your preamp you'll need 2 Y-splitters. 2 females into 1 male. 1 for each channel. Then plug your interconnects into these.
May I inquire as to what you are doing this for? And what with?

WHAT IS THE ADVANTAGE TO BRIDGING MORE POWER

In that case you wouldn't need the Ys, just a standard set of ICs will work as long as the end leads are long enough as the amp ins will be further apart than the standard side-by-side ins on a single amp. With bridging the amps you wouldn't be able to bi-amp. Bi-wire yes, but not bi-amp. I don't know enough about the 2140s to give specifics as to how to bridge these.
Yes, more power. You'll also have a dual mono system which is usually better than stereo. Better channel separation and such.
If you want to bi-amp, you'll need the Ys. Use one amp for each channel. This is what I would try first.
