Nuts and bolts.

blocks of 35 x 70 pine cut slightly larger than the wheels.
cut the black 'carpet' from the corners, glue blocks onto MDF then nuts n bolts through, then screw the wheels to the blocks

Can you access the inside of the cabinets? If so then, as the others have said, nuts, washers and bolts. If not, make a plywood dolly of the same size as the bottom of the cabinet, attach castors to that, and use it with the cabinet either permanently or temporarily attached. The larger hardware stores usually have a ‘cut shop’ where they will cut the plywood to size for you.

variation on this good idea above, get two strips of pine bolt the wheels to this pine the. Screw the life out of it to the base of cabinet,

Thanks folks, these were the two answers I was expecting. Not sure how accessible the innards of the cabinet are for bolts, hence the perhaps unrealistic hope of finding strong enough screws. A dolly might have to be the way...

My son was a roady for 2 years and when they bumped in or out everything was done on dolleys

Also be careful about fixing anything to a speaker cabinet as it may affect the resonance

Edit. Sorry, just scrolled up and noticed it was an amp, not a speaker.

tee nuts are pretty standard here
