How to not install your shit

I dont even know where to begin, 2 separate boxes, 2 separate size subs, random wires, boxes held together with a capacitor, A CAPACITOR. It amazes me how dumb some people are and why they would even bother to have shit look so raggedy. If your going to have some beat, install shit correctly. Why drive down the street with a fire hazard in your trunk, like a non secured/mounted battery. Fix this shit homie.
