4 channel vs 2 channel

Okay i just wanna know how wrong i am here... If I'm looking to get 2 12 inch subs that run at 300 RMS dual voice 2 ohms, i want to get a 2 channel amp that runs at 300 RMS at 2 Ohms.. so then each channel gets 300RMS and/or a 4 channel amp at 2 Ohms that runs 150 RMS each channel then bridge...
