Help with mids n highs amp specs

Is 4 x 150 @ 4 ohms 150 watts per channel with 4, 4 ohm speakers? Also 4 x 230 @ 2 ohms i could drive 2, 4 ohm speakers at 115 watts per speaker x 4 channels, and bridged is 430 watts x 1st and 2nd channel for 1 speaker and vice versa for the 3rd and 4th bridged? Thanks for any helpful info new to doing door speakers n such. Im wanting the ct sounds neo 6.5s 250 watts rms x 4 for each door and was gonna run their meso 6x9s 200 watt rms in a box under the seats of my 2008 chevvy hhr and wanting to put at least 70% of their rms rating to all of them off this amp is it possible? Im thinking parallel the 4 door speakers on 2 channels and running the 6x9's on the last 2 channels, my car has a factory pioneer sound system and i was gonna keep that factory amp also and put a pair of old kickers i have on the factory amp. I already have 2 12 inch subwoofers on 1500 watts at 1ohm and as u can imagine they kinda drown out the factory door speakers even on the factory amp lol.
