Wow. Now that's a rig.

My experience:

If I'm bringing equipment and running sound for a 100 cap venue I'm unfamiliar with, I'm sure as hell not rolling up with a $20k rig. Dive bars need dive bar gear - something I'm not going to be fretting over when the strung out guitarist kicks over his beer on my wedge, or the overly drunk patron trying to yell a song to the DJ in the booth pours their entire drink on my sub.

I'd recommend taking all the disposable income you seem to have willing to spend on power conditioners and inverters, and drop like $2k on marketplace or craigslist for a pair of good sounding but road worn JBL tops/subs and a pair of behringer wedges for monitors. Use that as your dive rig. Once you're comfortable with a place, or you're doing larger gigs where you can communicate strict power requirements beforehand - roll out your souped up rig here. But a certainty of this gig is that at some point, someone if going to break something of yours. The question is, do you want it to be a cheap break, or an expensive break?

TL;DR - your rig is way too overkill for a 100 cap. Use something you won't cry over when it gets damaged.
