How do I wire this amp/sub up?

How do you wire a light fixture that has a white wire black wire and a ground wire if you only have a white wire and a black wire coming from the wall?

• Answer:

  It is strange that a ground is not currently installed. For safety a ground is required. However, the good news is that a ceiling fixture provides little chance of a shock hazard except when servicing the fixture. However, the missing ground should be a warning that other things may be wrong with your wiring and you should consider having an Electrician check your overall wiring for issues. It is likely that someone has done some rewiring in your house and they may have screwed up other things.
