So, I have a Line 6 HD150 head hooked up to a Marshall MG412A cab. Now, everyone is saying if you do not hook up the head right and play at loud volumes it will overheat and blow. They say to hook up both the left and right outputs in the head. I see both the right and left outputs in the back of my head BUT my cab only has ONE input. Soooo, what do I do? And i bought the head used so I have no instruction manual.

I believe that cab is wired for mono only.

Your amp head should have an option for stereo or mono. You want mono. What you need to do is measure the cabs resistance (amperage or ohms) with a multimeter to be sure. It will either read something close to 4, 8, or 16. The set you amp to match that. If you have no tubes in that HD then it probably won't matter too much.

There was a very similar thread recently about these HD's. Where you a part of that thread?

Gnereally match head to cabinet on ohms. Multimeters are like 11 dollars...

He doesn't need a multimeter, it's going to say the amount of ohms on the back of the cabinet.

Cool.

Don't use a multimeter then.
