IMO you can do better with products from a different manufacturer. I can't really comment on the speakers. I've never heard any DJ speakers I thought were listenable.

That Pyle power amp, well it really is a "pile". The wattage rating is for peak not continuous power. You can rate an amp at any peak power you want especially if there is no time listed for it delivering that peak power.
Any decent manufacturer will list an amplifiers continuous power rating at 8 and 4 Ohms. I would guess that "pile" actually produces ~200WPC@8 Ohns. Personally, I wouldn't buy anything from a manufacturer that doesn't practice honesty in it's power ratings.

Check out B&H Photo or one of the musical instrument retailers that have a web presence. See examples below.

I mentioned B&H and listed them first because I've had very good experiences ordering from them and they have free shipping. The last order I placed with them was done over the internet before noon on a Monday. I received my order the next day. Usually when I order with them on Monday I get a UPS delivery on Wednesday.
