If the sub has a volume control, turn it down then turn up the volume on the amp to the very high volume you mentioned. If it still has very low muffled sound, then we know the problem is about the amp.

Subwoofer channel no longer has output

Is your sub powered (amplifier built-in)? If so, connect your MP3 player directly to the sub input and see if you hear audio. If you do hear audio, check for cable problems from Panasonic to sub input. If the sub is unpowered then it's either the speaker wiring, an intermittent sub and/or your Panasonic at fault.

Have you looked at the manuals?

If the unspecified sub isn't self-amplified it won't work with this receiver.

If it IS self-amplified you still needt o set up the receiver to run a sub.

Replacing a Surround Sound System Receiver

the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)

The subwoofer is the low frequency contribution to your sound. The "boom". Any brand will do...obviously, there are quality differences. Some units are powered...others not. This is probably not. Find a major store like Best Buy or Circuit City. They've been through this before. You can probably get info from Panasonic at their website.
