Hello I have a Kustom 5 watt amp head and it has 3 outputs 1 - 4 ohm 1 - 8 ohm and 1 - 16 ohm. how can I use my stero 2-12 cabnet which has 2 - 8 ohm inputs. correctly? I know I can plug the 8 ohm output of the amp into one of the inputs of the cabnets but I'm hoping I can use both speakers some how and still have the ohms match correctly. I always get the math messed up to make this happen. Can I use a y-cable to input both speakers from one of the outputs? Thanks in advance
