Electrical issues 3G TL

What’s going on guys,

My interior lights and power for mirrors stopped working, also unable to use key fob to activate/deactivate factory alarm/

unlock doors.
All problems began simultaneously.

One day I was trying to take this big ass sub box out of trunk and this thing (picture attached) sparked.
I do not use this car as my daily, I had it sitting in the backyard during winter but I noticed soon after that sparked happened.
Its been like this for over a year now and kinda annoying.

I had someone check the fuses under dash and some under hood which were all good.

Any ideas?

Thanks in advanced

- Lou

Small lights fuse under the steering wheel probably blew. Be more diligent and check all the fuses under.

Easiest and cheapest fix first would be to check all of your grounds and ground points. I've seen a lot of these cars start doing really strange stuff like this when the electronics have a poor ground. Had a family members car do the exact same thing, windows, door locks and some other accessories either quit working or started acting funny. Took all of 5 minutes to do.
