i have 2 l7 4ohm dvc, i plan and wiring it to 2ohm, my question is that i am running this through a 850.2. it says that will produce 425 rms x 2. does that mean each channel will get 425 or both channels will equal 425? also, if i do decide to bridge it, is it ok to run 2 positive and 2 negative wires when i bridge? any help will be greatly appreciated.
