Unfortunately those power rating are advertising fiction, in reality those subs have 500w amplifier and the tops are about 250w, I have the amp module from a TH18s on the bench right now and look at what is printed on the circuit board in the pic below...

The good news is those are the numbers you need to estimate power requirements, 1500w in speakers and maybe a another 200-300w for the small signal electronics means this will run off a 2kw generator, if you want to factor in some additional headroom make it 2.5kw to 3kw.

own/have owned for a decade now, a Honda EU2000. I can get by with it running (2) old mackie srm450 tops and a single mackie SWA1501 sub, plus small analog mix console and wireless mic setup. Could I run a second sub?  have never tried over the years, but the math looks to be really close.
Most of my outdoor/no power weddings I just run a bose L1c and power it with a battery pack (1200) unit that really is only pumping about 750watts, but it'll run the bose for several hours.
Largest non-commercial generator stage I've had to mess with used a honda 3500 for the band's stage gear..keyboard, (2) guitar amps, 1 bass rig, pedal boards and if memory serves I tossed the stage DMX lights on that same rig...then the PA was on a honda 7500..that was a pair of 3-way powered tops, pair of 18 subs, (4) powered monitors and a digital console...
back to the lil eu2000, it is quiet enough  if it's not running WOT and it's been great to have it when needed. But yeah, they are definitely finicky about their fuel mechanism...I always use non-ethanol, but if it's going to be a longer term storage , I'll disconnect fuel line and drain it best I can so the carb can run dry, cause the "off" switch does not let the fuel run out, so it kinda creates it's own problem.

I've run an outdoor House music show with my Yammie EF6300.  Four Th118, two SM80 on a DNA20k4, plus 2 DXR15 and 2 DXS15 (texas headphones).
The power meter on the Genny was at about 25% max.  Ran almost all day on a tank.

For long term storage, use a fuel stabilizer.

Update- Sorry I think i posted this in the wrong section. I'm new to this site!

My go-to is a Honda eu3000is (23 amps) for my 3-way rig (with Crown power amps: XS4300, XTI4000, IT6000), digital mixer, etc.
It handles the PA plus guitar/bass amplifiers well.

I have used the same PA (but with an analog mixer) for outdoor DJ'd events powered by a Predator4000 generator and it worked well.

The Honda is an inverter thus it is quiet thus you can keep it close-by the stage. The Predator is non-inverter, ....it's loud.....thus it has be be rather far from the stage or behind a barrier (truck/wall, etc).

Try renting one first.  If you are in the US, Home Depot rents the above Honda units (at least the Home Depots in my area do).

I rented one of the larger Hondas for a demo on the Red Bull HQ parking lot in LA. Two stacks of SH-96HO over 4x TH-118.  That demo rig was set up for 240v operation so I got the converter cable (IIRC that's the part that does it) and I got it as loud as anyone wanted it and the generator did not care.
