Hi, I'm knew to this forum. Just wondering what you guys think of this setup. I have 2 alpine sps-1042D 10" subwoofers (300watts RMS each) in a sealed box. Now the amp I plan to use is a soundstorm vanquish v900.2 which puts out 320 watts X 2 at 4 ohms. Am I better off going for a mono amp or is a 2 channel amp like the soundstorm a better idea?
