If you are familiar with my amps then try to be specific with ur answer but if your not then at least tell me the general idea thanks.

I have a FENDER PX2216 (MIXER/AMP) - 300W per channel and a QSC USA400 200W per channel AMP.

1)How do I hooke them up to end up with more power? (like 500W per channel maybe or what ever comes out).

2)Do I have to pay attention to the MAX watts on my speakers? If my Speakers are 300W (per 8Ohms) can I still drive 500W power to them?

I am a rookie when it comes to sound engineering and stage setup, so the more details the more I learn , thanks.
