Since it sounds like you've already blown a couple pairs of cheap powered speakers and have security problems, I would take a different approach. You will never be able to secure the gain knobs on the back of an amplifier short of modifying the speaker with a metal box over the knob.
Instead of taking a powered approach, consider a pair of passive speakers. You can get excellent sounding slightly older passive speakers on the used market if you are willing to trade weight for price. For instance, look on your local Craigslist for a pair of EV SH-1502 speakers. You should only have to pay $300 a pair and if you can deal with the fact that they're 70lbs they sound much better than any Alto speaker or the cheaper EV ZLX, ELX, etc...
You then need an amplifier - preferably one with a security cover. The EV SH-1502s are very efficient, so you can use a small amplifier. QSC CX 302s are expensive new but very cheap on eBay.
You will also need a stereo rack mixer - again, you should be able to find what you need on eBay. Pick up one of these to protect the mixer: http://www.amazon.com/Raxxess-Locking-Security-Cover-Space/dp/B0006ZXF7O
Put the electronics in an audiopile rack (http://audiopile.net/products/Cases/RUE_Roadracks/RUE_Case_products_page.shtml), put it somewhere safe, and run the cables as far as you need.
