i have a 400 watt behringer cab, and i read that you should get a power amp that produces double the wattage of your speakers, so i found this

http://www.bestbuy.com/site/olspage.jsp?skuId=8568016&type=product&id=1210981699352

i've also got 50 dollars worth of gift cards at best buy, so why the hell not

so can i do this-

microphones--->into unpowered mixer--->into that power amp---->into my 400 watt behringer cab?

or i also have a 120 watt crate cab, but i was gonna use that for my guitar, but i could switch the duties of the two...


another question-
i have a 120 watt randal head(rg100ht)and i was wondering if my sound would be any better if i used that same power amp between my head and my 400 watt cab?


so it would be-

guitar-->randal 120 watt head---->800 watt power amp--->400 watt cab

would i notice any difference?

No, you're cab should have a higher wattage than your power amp.

Otherwise the speakers will blow.

When you're matching a Power Amp to a PA Speaker, a good rule of thumb is to pick an amplifier that can deliver power equal to twice the speaker's continuous IEC power rating. This means that a speaker with a "nominal impedance" of 8 Ohms and a continuous IEC power rating of 350 watts will require an amplifier that can produce 700 watts into an 8 Ohm load.
