  1. Beau, you would need five components:

    1. Car Subwoofer
    2. Car Subwoofer Box to house your car subwoofer.
    3. Car Audio Amplifier that matches your subwoofer power needs and ohm rating.
    4. Car Amplifier Wiring Kit that can handle the power needs of your amplifier.
    5. RCA Line Out Converter to feed an audio signal from your factory radio to your aftermarket amplifier.

    First run all your amplifier power from your car battery to where you plan on mounting your amplifier. Next, run your ground wire from your grounding point to your amplifier. Wire up the RCA Line Out Converter to the rear speaker wires to get a full range audio source. Next, connect one end of your RCA jacks to the Line Out Converter and the other end of the RCA jacks to your amplifier. This will provide an audio signal to your after market amp. Lastly, connect your subwoofer to your after market amplifier using the speaker wire in the amplifier wiring kit. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2003 BMW X5 amplifier and subwoofer installation.
