I want to run a Yamaha CP2000 poweramp bridged into 2 Aguilar DS-112s for the massive headroom. The Yamaha only has binding posts for bridging, and my cabs have Speakons and 1/4" inputs. Is it OK to use binding posts on one end or a cable, and 1/4" on the other? I realize it would be better to use the Speakon, but I already have 10-gauge speaker cables with big 1/4" plugs. Another query: I'm using huge 10-gauge cable, and the binding posts on the amp have a hole to put the stripped cable through. The hole is much smaller than the cable, so I had to cut down the stripped cable quite a bit to get it to fit through the hole. Does this greatly reduce the power going through the cable? Sorry for the dumb questions, but in almost thirty years of playing, I've never used a separate power amp and preamp; just heads.
