A:Answer This is a four channel speaker app, you could dial this thing down to two channels to push two separate subs, but you'd only get 300 watts per channel. It's best to purchase the mono block if you are pushing subs. I have this amp, and it makes my type r components and 6x9's roar! Check out the 1.2KW PDX M12 for your monoblock. Mine pushes two type R 12"s beautifully.
