"Your amp will make 4000w of power if it is on life support and there is a power surge. On a good day, going downhill, all oars in the water, the turbo wide open, the gerbils running at full tilt on the treadmill, all batteries charged to the top, 20 cans of JOLT cola + Red Bull, it is going to make about 800w rms of power into 4 ohm mono. Are you after one sub or two and what price range?"

i saw this and it sums up a good point "just becousr the kid who sold it to you said it do does not mean it does "
