I hope there's a sound techy out there that can help me. I am setting up a second karaoke system that I can run. Because of my size and age, weight is a real issue, as I will have to load and unload this system myself. What I have: CAVS 203G USB Player 7.7lbs VocoPro PKJ-9090 Mixer/Amp Combo. 450 watt amp. 25lbs. If I run two speakers off this amp, does that mean each speakers output will be 225 watts? Is that going to be loud enough for a small bar? My questions: Should I buy another amp to back up this one? I would like to run at least two speakers plus a monitor speaker. Could I put powered speakers with this system, and not have to worry about my amp wattage? I was wondering if I could get powered speakers and just run the mics and the monitor off the PKJ-9090. Also trying to find a case that will be light weight and have some room for expansion. Any suggestions or recommendations of what might make my system better will be greatly appreciated.

I looked up the spec manual for your VocoPro PKJ mixer/amp. If you use 8 ohm speakers, you will power a pair at 80 watts each or 160 watts average. If you use 4 ohm speakers, you will power a pair at 110 watts each or 220 watts average. The 450 watts is really the "maximum" or peak and is not what is usually considered the RMS or average power output for speakers over a long time of performance. If you can get the 4 ohm speakers it would put out more volume than the 8ohmn ones. That should be enough for a small bar. Speakers are also usually labeled as say for example: 150 watts RMS to 300 watts. That means you should use the 150 watts as your average use. Most of the time the peak watts on a speaker is double the average rating of the speaker. You can get a powered speaker for a monitor and hook it up to the Vocopro PKJ "booth" jack which is a 1/4 jack so you will either need a 1/4 inch speaker cable to plug into the booth and then into the back of the powered speaker. If the powered speaker does not have a 1/4 inch jack then you can probably get an adapter from whatever jack it has to the 1/4 inch size of the speaker cable.
I'm not sure if you can use powered speakers for your mains since the mixer has the built- in amp.
Something to consider is that if you buy the speakers and the powered monitor speaker, try to buy them within a day or two of each other so that you can test the whole system. If the speakers don't make the cut for you hopefully you could return them depending on the return policy where you buy them so check that out ahead of time too.
The lighest cases I know of are the molded type ones definately not the wood case which are heavy. You will need to make sure you get one that has a solid rack system and not a fragile one. Probaly a slant rack for your mixer on top and some space on the bottom for your Cavs player. Maybe Voco Pro has a case for the mixer/amp?
Economizing is a necessity in every walk of life, and so when a person is shifting, they would obviously prefer to get cheap moving boxes for the purpose. While moving boxes are a necessity, the cheapness can refer only to the price, because no one can reconcile with cheap quality. The common solution for this problem, which everyone resorts to, is doing as much cost comparison as possible. One should do both online and offline market research to zero in on discounts deals, which offer cheap moving boxes without compromising on quality.
Those, who have a large quantity of materials to shift, do end up getting cheap moving boxes, because many companies have package deals and combo packages, which work out cheaper than buying specific numbers of moving boxes separately. And those, whose job pattern or personal preferences make them shift frequently, will have no problem in having their own cheap moving boxes because they should ideally store the ones that they have used for a previous shifting, in a way that they will come in handy for the next shifting as well.
And those who have space to store, and know that they will have to shift sooner or later, should not throw away the packing cases, and packing material, in which their computer, stereo, printer, mixer, television, or any other gizmo, has come packaged. The original packing cases will always be the best suited for packing electronic goods, and will work out as cheap moving boxes of the best quality for shifting those objects, especially if you can afford to shift them in your own car.
One of the ways in which a person can balance the cheap moving boxes equation is by deciding whether he will be shifting by road, rail, or by air. Those who are comfortable with long distance driving, can drive their own luggage all the way, even if they are moving to a faraway place that will require two or three days of driving. Since they will be loading the truck themselves, they should be careful to load the heavier boxes below and lighter ones above. If loading can be arranged that way, they can buy cheap moving boxes of lesser strength for packing lighter stuff, and stronger ones for heavier stuff.
So far as one is moving within the same city, making some of the existing household stuff double up as moving boxes can solve the problem. Turn your blankets and bed covers and quilts into improvised cheap moving boxes by tying up things in them securely and loading them up in the back of your vehicle. Of course, when you load and unload your vehicle with these blankets or quilts, you might look a bit like a prehistoric character, or at least an 18th century farmer loading his mule on his way to the market. But then those bundles are the best cheap moving boxes that you can have!
