What do I need?

[ShinyC10]

These are all the "upgrades" I have to my truck and am currently facing some electrical issues. Looking at these things would I have to have a high amp alt and/or aux battery? Or would upgrading the wiring in my charging system do the trick? My alternator and battery are pretty much stock right now. My system ran for around 8 months with no problem then my start got stuck engaging while driving and ended up melting my alternator batt wire. Any help is appreciated
