I personally find all of this talk about PA doing the job misguided.
At BEST CASE scenarios, you get to run through the monitors enough where it feeds yourself. Typically, running bass through PA monitors isn't the priority, melodic instrument and most importantly vocals are the primary inhabitants of monitors. A LITTLE bass in there usually suffices for when you are far from your amp. And yes, if you had your own submix, yes you can do the job. but the amount of people who say to rely on that seems crazy to me. Yes I play mostly at venues and events with PA, and this is almost always the case IMO.
That said, if no one has said it, different amps have different watt ratings but all watts aren't created equal. My main travel rig is 2 2x10s and a Little Mark III head. Totally takes care of a lot of volume. That said SLEEP is a huge rumbling on the low end. But I would think an older GK800RB would be the cheapest way to get that kind of wool. Other than that, tubes to get that kind of tone.
Personally, I wouldn't worry about that and just get a setup you don't mind moving a lot, and a head that you won't have to replace. Do what you gotta do to get the right head, get cabs off craigslist or something. Maybe the head as well.
As for an actual number, 350-500W. Ampeg watts probably need closer to 500, Markbass and GK should be good around 350.
