Infinity IRS Betas Make Loud Noise When On


I just recently purchased some used Infinity IRS Betas. With both base towers hooked up to the crossover, the system makes a loud noise when I turn the control unit on. If I unhook the left speaker, then I don't get the noise and the sound is fine, but I hear a low hum. Same thing if I unhook the right speaker. I only hear this loud noise when both speakers are connected. I have checked, double-checked, and triple-checked my connections, and all looks correct according to the manual. Also when I disconnect the servo control unit and play them as full range speakers, they play fine. Does anybody have any idea what could be the cause of the problem?

I have an Aragon 28k preamp. I have an Emotiva XPR2 amplifier. I am doing all the hook ups without the mid-high panels connected because I don't want them to get shorted out, so I am only hooking up the base towers for now. I don't have anything else plugged in. I am using Monster cable interconnects and using the stock servo wires that came with the towers originally. Any help would be greatly appreciated.
When I hit the power button on the xover, I hear both. As soon as the green light comes on the xover, it pops really loud and it goes into protection mode.
