would it be a good choice to get an Audiobahn A4002T and an Infinity 1232W 12" DVC 4 ohm sub 300rms, and then bridge the amp so it puts out 400rms, but then wire it up to 8ohm? and about what rms do you think would be giong to the sub? would this be a good solution i can get a good deal on it and am tight on cash. thanks
