Hey guys i have a problem.

I have a digital audio 4606c amp and it has 75RMSx4

Heres the problem:

I have two infitity speakers plugged in two the front two channels of the amp, and they work fine. But then I plug my audiobahn rear fill speakers in to the other two channels and the protection light blinks and every time it blinks a very high pitch kind of beeping sound comes from all speaker that are powered by that amp then i unplug them and the infintys work great again. it seems like the audiobahn speaks are causeing some kind of problem, what could it be? i havent done much trouble shooting yet but i figured you guys might be able to help.
