Since this is DIY audio, I'm going suggest that you take your powered speakers apart and see how much the amp section weighs, and if it's possible to mount it in a spearate box/rack case. Also, I strongly advise the use of a subwoofer, most PA mains have very little bass, except for large cabinet 15's or 2x12's, etc. A small 15" sub will work wonders.

Does the sub replace the woofer? Do i mount the one of the amps in the box then configure it to power both speakers?

Kinda gotta spell it out for me, since I'm learning

Most basic PA speakers ("tops" or "mains") are 2-way, with a horn tweeter and normal woofer. The woofer, even 15's, handles much of the midrange usually well over 1000hz. These woofers are very sensitive, but typically have poor bass response. Once you go and put them up on stands and out into a room, it gets even worse. Subwoofers ("subs") are intended to be used in the bass frequencies below the range of the main speakers. Typically with an active crossover and amplifer, but having a sub on a passive crossover is possible.

In a nutshell: keeping "small" speakers (say 10"+horn) as you seem to have now, will keep their weight reasonable.
As suggested above, going for digital amps + NEO speakers + plastic cabinets (all of which scream "MODERN" speakers) will save you a ton of weight where it matters: over the mounting poles.
The subwoofer will be large and heavy, but it lives at floor level, and may be fitted with wheels.
So *total* system weight won't be low, but you won't have to lift the heavy component.
That's something.

Ok coming out of the Numark mixer, I have left and right outputs for the speakers.
1. If I add an amp, do I get a "Y" cable going into the amp out of the left & right ?
2. Do most of the amps have left & right outs?
3. Got any suggested manufacturers for the speakers, amps and subwoofer?

There are several ways to plug a mixer into a pair of mains and a sub. Most larger mixers have a 2nd output pair on the same volume control, so you could use that. A splitter cable is an option and should work. In both cases, you would want to have at least a low pass crossover built into the subwoofer (or amp) to cut out the higher frequencies, and possibly a high pass on the mains.

Or if you were to use a separate crossover box, it would have both a high and low output.

Or, if you got a powered subwoofer, it may have a line level input and output, with a crossover built in:

I agree with that.

I have a pair of cabs using eminence delta 12's, rated 400 wrms. Also using a selenium DT205TI with horns. There is a cup in the bottom.

The cab is sealed, .7 Q. I put two input jacks on this cab. One goes in full range, the other is into an additional 100 hz hipass. I'll use them alone for a smaller venue.

When I do a larger venue, I have a pair of 15 reflex cabs with a cup in the top that I put a pole into for the upper cabs. I connect a small cable from the 15 cab to the hipassed jack in the 12 inch cab.

I use an RMX 1450.
