The impedance levels are different between your amp and subs...I have the exact same amp and problem, if you figure out how to fix it let me know...

Do not know how to remove blade

Take knife cover off.unplug.get a tapered punch about 12" long rotate the blade where as the nut in the middle of the blade has a flat side horizontal.right is tight left is loose.counterclockwise to loosen.Put the punch on the left side of thre flat and hit the punch with a hammer sounds odd but it works well yes it will bang up the side of the nut but it will not hurt anything.If done right it will loosen nut easily.I work on slicers all the time this is the only method I use.It may take a couple of good wacks but it will come loose as you already noticed a socket or wrench will not stay on the nut .good luck.

Problem(s) Description(s): Initially intermittent output with good audio quality on all four speakers/channels,( five minutes of output then maybe two minutes of silence) then no output at all on all four...

yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Stihl bg 55 blower runs good for 5 min. then loses power

1) carburetor gaskets/diaphragms may need to be replaced

2) ignition coil may be breaking down when hot

3) check compression when cold, then after it stops, when hot

4) could have a vacuum/pressure leak

*I would investigate carb first

Rockford fosgate punch 700s gets very hot

Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.
