I had read that the OP had already secured a genny (and a very nice one at that...) so I brain dumped that info just in case it may prove useful to someone in the same position. I wasn't aware that he was only running a small Lepai amp, so my requests to him to trip the genny may be a bit ambitious

I've run my XTi 2000 on a Honda EU series generator a few times in the past - always supplied by the event planner or client - and never had any issues with a single T39 and OT12s.

Planning on bringing single T39 and single OT12 for this one. It's Zydeco/Second Line themed, but we pre-game with Top 40 for the kiddos to get amped about Homecoming.

You'd be surprised! 2x T39 and an OT12, amplified with a Class D car amp would make quite a racket only pulling 5 amps at 12v, which is 60w...

As mentioned, this isn't really answering the OP's needs any more but moreso pushing my point that with some not-so-conventional thinking you can make decent noise without much effort.
I wouldn't suggest running out and spending $x00 on such a setup for a one-off event, but a SURE TK2050, MiniDSP and a 15AH SLA would be very handy to own if want to do events outdoors without the hassle of generators. Especially when generator noise and placement is a concern, for background audio and more social-oriented occasions than a straight out band/dj gig.

That said, there's a threshold with battery powered systems that a generator and lightweight amp ends up being a better solution, but that's when we're talking about needing 50kg+ of batteries and multiple 12V amps... but strike the balance and you can have an impressive portable setup with cheap and simple parts - high sensitivity speakers like BFM's are perfect for this!

that's my ranting done, for now

I'd love new toys, but considering I'm doing this for free... investment will be $0 from my company I don't do these kinds of things often - 3rd year in a row I've done this for my sister, but nothing I'd plan on doing consistently enough to warrant new gear.

So an update:

The gig went off fantastic. I powered my Macbook Pro and a Crown XTi 2000 off this generator:

Which was tiny! It was as deep as the Titan 39, but shorter and maybe 15" across. Fit very nicely in the bed of the truck. Played for over 2 hours and had zero issues. Single OT12 and T39 at almost full tilt.
