how many watts (rms) will my amp be distributing with 2 speakers and 1 sub?

I have a powerbass 1280watt amp. According to the powerbass website, the amp can put out 100 watts x 4 at 4 ohms, 160 watts x 4 at 2 ohms, and 320 watts x 2 at 4 ohms mono...but I downloaded the installation guide and it shows that I can hook up 2 door speakers, and 1 sub...wouldn't that be 3 channel? the website or the owners manual doesn't give details of how many watts it puts out for the 3 channel mode...the door speakers are 350 watts peak power, 60 watts rms max and the sub is 500 watts peak power 150 watts rms i think...

yeah...that sounds about right...100 x 4 wat 4 ohms with 2 speakers would be...200 watts lol do you think i'm going to be overpowering these speakers a little too much? i already have the door speakers installed and running and they sound pretty freekn good

that will be way to much power for the speakers , just turn the gains down a bit,set the front on hp at 120 hertz to. it will help
