What do you mean by "experience"? And "subjective"? I'm not sure what you're talking about.
By experience I mean anything which we detect with one of our senses.
The subjective part is, IMHO, the key to qualia.
Suppose that you've never seen red light, and that you are then told all of its properties in perfect detail. You would still gain new information by actually seeing red light, because you still don't know "what it feels like" to see it. The qualia is not the objective facts, but rather what seeing the light "feels like", your perception of the effect produced on your brain by the light.
(Qualia are usually taken to be an argument against materialism- because after you know every objective fact about something, you still gain new information (qualia) by experiencing it.)
