maybe RGB. $1.5k for the lighting.
Liquid Lumens RGBW with a little discount would be right at $1500 for the lights and controller. But the light is outstanding!

Beyond those, id suggest the Lumitec Seablaze X Spectrum RGB. A pair and labor might get you under $1500 for a decent light.

have a shop fab a sub box
Arent the 19' coming with all Wet Sounds? if so, and there is not an enclosure behind the woofer, then I would speculate that its the Revo FA woofer, no small enclosure needed. id confirm this before moving too far on this.
