How do I hook up a 2 channel amp and a 4 channel amp to run 4 10's

I have a 1200watt 2 channel amp hooked up to two Infinity Ref. 10's. They arent bridged. And I have two Sony Explod 10's also to a 400watt 4 channel amp bridged. The 2 ch. amp has an output for RCA Jacks to go to an other amp. But When I hooked up the two amps the subs made a low pitch popping sound. WTF?
