For what you want to do I'd suggest you build light portable powered boxes, and add-on as many as you want, depending on venue size.
The basic one would be a 12V powered bridged chip amp.
Either the 2 x TDA2003 yiu suggested above, or a TDA2005 which is the same, but packed on a single chip, or one of the more modern TDAxxxx (do a search) which replace them.
A simple light 10mm plywood box might carry *two* 8" 4 ohms speakers, each driven by its own bridged chip amp and both powered by the same internal 12V 7AH gel cell.
Quite carryable, cheap, and *loud*.
For highs add 1 or 2 LeSon TLCsomething tweeters, *very* loud because they have internal voltage booster transformers.
Somewhat piercing sound, but in your particular situation, that's an asset, makes it reach longer.
For speaker(s) I suggest Guitar speakers, much louder and more articulate than regular Hi Fi types. The Jensen MOD 8-20 in 4 ohms is very good and costs around U$23, how's that?
To show that I do what I preach, here's one example of my "Callejero" ("Street Guy") amps, in this case with an 8" 4 ohms driven by bridged TDA2005 and a LeSon Tweeter driven by a TDA2003 , custom made for a Street Tango Musician.
LOUD and CLEAN
The lonely unmarked knob between channels is a separate volume/attenuator for the LeSon driving amp, because 10W of "just highs" is usually TOO MUCH ... although in a large, boomy Basketball court or in a noisy Subway station, it sure helps.
Mind you, I'm suggesting you build double this in a somewhat wider box
PS: Et oui, mÍme moi, je suis aussi Francophone, mais laissez-nous continuer en Anglais pour nos bons amis
