    If the blue/blue-white pair and the orange/orange-white pair went to the speakers in the headphones then you should be able to connect each. Left speaker connections to Left input, etc. if you remember which went to the positive speaker terminal then that is plus for sure. If you get the polarity wrong it will still work but the woofer will retract inward when it should be going outward on a kick drum.
    The output may be too high for the input of the HTiB so make sure that the volume is all the way down and bring it up slowly. If it is too high there will be distortion noticeable at all volumes. You can connect a stereo volume pot to reduce the output if needed.
