speaker system 1000 watt image
Reis
I currently have a 1000 watt Phillips home theater system and would like to get rid of the passive subwoofer and put in a powered subwoofer. The phillips system does not have component audio outputs. It only has the two small speaker wires that go to the subwoofer. Please let me know how I can hook up a powered subwoofer to this system.

As others have said you can't do much to an all-in-one system ... and changing to a powered subwoofer won't do anything for the midrange and treble, or for the power/loudness. So making the change you propose is questionable at best (You would be wiser to buy a better system)
That said, the other answers saying you can't change to a powered subwoofer are (probably ... it depends if the system is sending full spectrum sound to the main speakers) WRONG. If the powered sub has speaker input terminals (in addition to RCA input(s)) you can. These usually take the form of two sets of speaker input terminals (left and right), and two output terminals (left and right). The sub has a crossover built in, and by running the wires from your HT for the right an left front speakers to the sub, and then new wires from the left and right output terminals on the sub to the right and left front speakers (being careful to respect polarity to maintain phasing) you can get the powered sub to work. In essence the full range audio goes to the sub crossover, the bass notes are split off to the sub amplifier and from there to the sub speaker, and the mid and treble notes are sent on to the front right and left speakers. See the link for a picture of a typical sub interface panel.
Note that you need to make sure the HT is sending full frequency sound to the front speakers (use the "Large" option if there is one in the speaker setup). Your system probably doesn't have this setting, but more than likely you are getting bass sent to the main speakers and the above will work. If it doesn't you can either return the sub or use it with a new upgraded system (your best choice anyway).
Next time provide details of model not just brand!
Hope that helps.

Answer
Unfortunately, many HTIB systems and other similar home theater package systems just don't give you the flexibility that a modular system would give -the price you pay for budget-minded convenience. However, you should have an AUX OUT or an alternative AUDIO OUT that you may use as a SUB OUT. Even the CENTER OUT would work if you have one on your HTS.
Or, as a couple of options, you could either get a higher efficiency/performance passive sub if you just need more performance, or add a subwoofer amplifier to your existing sub.
I have some recommendations for excellent examples of powered (and greater performance passive) subwoofers at different price levels for you to put on your short list...
Happy listening!
