300W RMS sub
100 W RMS x 2 for front components
100 W RMS x 2 for rear speakers
So you are looking at a 700W RMS amp to fill the power requirements (don't be fooled by the RMS "range" of the speakers...you must use the highest RMS available when planning the system, otherwise your speakers will be underpowered).
Choose any amp that fits your budget. I prefer Kicker myself, but that may not be someone elses preference. What matters the most is the amps RMS output, not it'* max (which is what alot of amps are rated at, so be aware of that when shopping around).
