Why do I need power management if I have a great power cord?

I must be really really stupid not to understand much of these past several posts. I would hope the people commenting in such a technically proficient way would recognize that most readers have no clue what they’re saying.

They don't either.

OK. What is far more likely is that the 48 Amp value is actually how much current is present when the power supply of the amp is shorted. Its available to the output section in the form of charged capacitance. This is used to help reduce IMD in the output section and is not something that the output section can pass to the loudspeaker (if you see what I did there 😁).

Yup, caught that. Shorted or driving Acoustats 😁 Talk about a vicious load for an amp. They were the reason for Ampzillas and Crown DC300 amps! The DC 300 would drive a cast iron pipe or a welder! 🤣

I have a 300A welder.
However I do not use it for speakers.

And I would not consider a Pass amp for use as a welder, but it might be cheaper than some welding machines.

I just went from one to two subs and my wonderful monitor speakers along with an integrated upgrade. Just a couple of days a gi I realize I’m not getting any change in bass response and while my monitors sound great my home concert hall was lacking. Sure enough both sub fuses blew, yes power surge( Florida go figure) I had upgraded my wall outlets and power cord but simply forget to plug into my McIntosh power conditioner.  My one piece of Mc gear left. Simply over looked and now back to glorious sound. Yes that was an expensive piece but it will stay put

How much did the fuses cost?
Are ythe subs working with the new fuses installed?
