    1. Blue Wire - Amp Remote turn on

    2. Red Wire - Ignition Wire

    3. Orange Wire - Illumination (not neccessary to connect)

    Yopu need to connect the blue flying lead on the adapter to the power antenna or "remote on" lead on the HU. It will usually be another blue flying lead clearly marked

    Try re-earthing the HU, chassis to chassis of the car

    Yes you could if you want to reamplify the distortion from the Bose amp.
    You'd be far better off running a new RCA from the sub pre-out of the new HU, this will also give you independent control of the sub
