Hello, I have a Samsung 5.1 surround sound system, recently I had a lightening strike very close to my house. Immediately after the strike I could hear a loud humming noise... took a few tense minutes to locate :-/
So first, I unplugged the cable going to the sup out connection on the back of my amp... no change. Is it safe to say its fried?

The humming might be cause by a ground loop problem. Try plugging it in another outlet in different places in the house.

Playing at a lower volume, the sound settings is changed or maybe the amp is "semi fried" but I'm thinking the woofer might of got "semi fried", most likely the voice coil. Without knowing the model of your 5.1 system, if all other speakers sound good, the sub's voice coil got damaged.

Did you smell anything burning? If you can get into the sub(unplug and wait a few hours just in case for the capacitors to power down) or just don't touch any live wires and inspect the sub speaker. IF it looks melted, burnt and extra, the speaker is gone.

Edit: PS: All electronics, computer, TV, stereo and such should be plugged into a good surge protector and don't use those cheapo power strips. I use APC products, not so much for the battery backup(stereo, HT, TV doesn't need it) but for the surge protection.
I use old APC products and the batteries are no longer good but still offer excellent surge protection. You can find them cheap at a thrift store.
