Old Kenwood E-Servo?

I have a car in the shop with an old Kenwood Amp, model number KAC-816. On the speaker barrier strip its laid out in the following fashion.     E-Servo-, speaker -, speaker +, E-Servo +. What the heck are these E-servo terminals for. I remeber seeing them before and for some reason I thought they needed to be looped into the speaker outputs on this amp but I cant remember now. Im hooking up a pair of single voice coil pioneer 12's. Any help would be appreciated. Thanksdouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
