Just got a Spider 3. My old Behringer GX210 digital PCB has stopped working but the cabinet speakers are good, powered through a separate system and are Jensens - 10” x 8 ohm. Can I use my 1/4” pod style/line out on the front of the cabinet (next to the on/off switch) directly into the back of the Behringer with a Y cable for left and right? Seems a waste of a decent set of 2x10” speakers and would boost things right up.
