Cerwin-Vega SBL3 Wiring help.

[BigGreenWeenie]

Ok, so I know little to nothing about electrical and I'm trying to make this work. I purchased (like an idiot) a SBL3 - Ten Speaker Waterproof Soundbar System with LED
that's wired for a boat. I'm either going to send back, or if possible, wire to standard U.S. home outlet (this's the crux). I've included three pictures. The first is the power cords, the second is the auxiliary crap I don't really need as it's Bluetooth and that's what I'll be using. The third is their wiring diagram for use on boat/electric vehicle and gas vehicle. I'm hoping I can just purchase a convertor and move on so hence the questions. Thanks for anyone who replies, I appreciate it!.

I'm thinking this would work?

That will work. I was going to say likely overkill at 50A, but not sure how much the bluetooth receiver would pull...

That power supply may not be the cleanest power. If it hums, put a capacitor inline.
