So i have 2 dvc 4 ohm subs with 400w rms each. amp will do 300x4 @ 2 ohms or 600x2 @ 4 ohms. i want to get my subs to each get around the 400w they can take but i can only wire each individual one at 2 or 8 ohms resulting in only 300 watts max no mater how i wire them. is there any way with out adding another speaker or losing any power to either sub can i raise my ohms from 2 to 4?
