bridging two home amps

could some one explain how to plug in the rca interconnects from two amps to a preamp

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?

i was going to bi amp my polk rta12 speakers ..so i have two nad 2140 amps ..and one phase linear preamp 3000 SERIES II.. ON MY AMPS THERE ARE RCA NORMAL IN L&R ,AND LAB IN L&R RCA PLUGS AND A BRIDGE BUTTON ON EACH THAT IS COVERED BY A PLATE I THINK ONCE YOU BRIDGE YOU REMOVE THE PLATE AND PUSH BUTTON TO OUT POSITION.MY PREAMP HAS LEFT AND RIGHT FRONT OUTPUTS

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.

Nice rig!
