2006 Audio Options for S677 (USA)

Bought a used 2006 3.0 back in August. The sound was pretty amazing I thought until about a month ago. It now sounds like every speaker is completely shot which I am told is likely the amp has died on me. I have checked connections to the amp and the fuse and don't see any issues. I have not pulled out the head unit to see if there is a connection issue there.

(The previous owner did install the GROM BT3 addition to this system)

Assuming it is the amp, it seems like a complete PIA to upgrade this system. I have read this post:
https://www.zpost.com/forums/showthread.php?t=1480355

My understanding is 677 is the highest of the 3 audio options? Is that correct?

Regardless, if I need to replace the amp, from a quick search, it isn't cheap. Do I have any other options for replacing the amp?

If it makes sense to do a gut, then I would love to install a single din flip-up head unit but that looks like a pretty big DIY job.

Any thoughts/pointers/tips would be greatly appreciated as I can't stand the sound right now.

There are a lot of threads on replacing head units, search should be helpful there. As for the amp I'd scour eBay for a used one. I suspect the same unit is used in various models so it might be easier than you think.
