The thread title sound weird, I know. But here is my situation. A while back I bought a new GK MB115 combo. Shortly after a year the head died. I was so busy with school and work that I wasn't doing any gigging at all, so I let it slide when I couldn't get the repair covered. Fast forward! I've been using my trusty Fender Rumble for bedroom practice, but now I have gigs coming up and I need a bit more oomph. My plan is to use a TC Electronic BH250 on the GK cabinet with the old head removed. I dissembled the amp/cabinet today and it's pretty basic from what I was expecting. The wires connecting to the 15" speaker use "slip on" style quick connectors with a simple red/black wire situation, so my main question is can I use the red and black wires and connect them to a speakon plug and run it to the BH250? Edit: I just remembered that I have a horn/driver on the cabinet as well. I'm not sure how to go about wiring that....hmm My apologies if my wording is hard to understand. I am very new to wiring and all this.
