I've only ever owned 1x subwoofer, and that had a single cable. Yesterday I received a new Pioneer Ax5Ai amp with a dedicated subwoofer output and a Canton ADS 25 sub. The sub came with a Y-splitter (out of the amp) but no cable, and accepts seperate L&R phono inputs. Luckily I had a cheap phono cable lying around, but now I'm confused as to what cables to buy. I was looking at QED sub cables which all seem to be single connectors at each end. Assuming also, that my Y-splitter is a reasonable cheap connector, I want to replace it with a single phono to double phono lead. Would a decent quality stereo phono lead be the right choice? Is there something special about dedicated subwoofer cables, and do they come in the configuration I need?
