    I can turn sub off...when I take trips I will have 2-12's...I don't want the 3rd row bassed out completely...the subs will be off or down real low so it'll work

    I might look into the factory Pillars that he had pictured i love the placement of them i would just have to swap out the factory speakers. I also like the amps under the seats i might have to check if that will work for me before i install it in my rear panel cause i would really prefer to weld a battery rack in there

    For anyone interested, I'm doing this mod on my 2013 Expedition - add the OEM Lincoln speakers to the rear. The part numbers I got from the dealer for medium light stone colored trim (18978B) are:
    • 7L7Z-18978-DAB (LH $54.96)
    • 7L7Z-18978-CAB (RH $64.96)

    Thanks for the part numbers. This seems like a good addition to the sound system

    Just want to make sure you know that these are the speakers ONLY.


    They require the d-pillar trim / housing / pod for the speakers to mount to. This is the same trim where your 3rd row seat belts mount to.

    Here are some example part numbers for those. They vary depending on standard/extended length and interior color.

    * 7L7Z-40310-11AA dealer list price $184.57 driver side
    * 7L7Z-40310-10AA dealer list price $182.85 passenger side

    Unfortunately, these are the speakers + grilles only, as I found out when they arrived. The actual "D" pillar trim is <31010 IIRC.
