• Answer:

  k pretty much all in all a sub is ur speaker haha. it puts out the bass, to do this u need a power source to run it. thats the amp. the amp runs the subwoofer. now wattage is pretty much the measurment for how much it takes to run the sub. so example, u got a 500 watt sub. so u want a 500 watt amp. theres also ohms, 2,4,and 8 ohm. all u wanna do is match the ohms with the amp u buy. so another example is that, 500 watt sub 4 ohm, u want a amp thats rated at 500 watts and 4 ohms.
