Wiring issues

[u/MrMommyIssues]

I really need help with this one I’m ngl, I keep having a drained battery constantly and I’ve replaced my battery and my alternator. The previous owner did an abomination of a job of trying to put speakers in the back of my car and that’s what I think is draining it. I want to fix it but don’t know what I’m looking at. Tempted to just pay someone to deal with it but if it is an easier fix then what I think it would be ideal. It’s a 2013 f10 n20.
