200 watts isn't going to be enough for a bar for a full band, particularly if they're playing amplified guitars. 1000 watts is about where I'd start, I think. More if I have passive monitors.
The Phonic is nice, too, but you can put together a bigger system on the cheap if you want, and then grow it according to need.
Amazon has these...
Mixer for $200 (I own this one and will vouch for it's quality)
http://www.amazon.com/Behringer-X1222US … amp;sr=1-4
1400W 2 channel (to power mains and monitors) amplifier $125
http://www.amazon.com/Pyle-PTA1400-Prof … amp;sr=1-1
2 500W speaker mains @ $65 each ($130)
http://www.amazon.com/PYLE-PRO-PADH1079 … mp;sr=1-52
2 600W stage monitors @ $60 each ($120)
http://www.amazon.com/PYLE-PRO-PASC12-T … mp;sr=1-12
Total cost for a complete 1400W 16x2 system around $600 after cables and taxes. This kind of setup is expandable and configurable. The drawback is that it's a PITA to haul around.
You can always upgrade different parts if you want to. These speakers can handle a total of 2200W RMS, so you can upgrade the amp without having to re-buy speakers but if you think you want bigger, spend a little more and get some more headroom on your speakers. Or you can just keep the volume down a bit.
Someday we'll win this thing...
