Sub woofer connection

    Ok, where are my connections for a sub into the 2023 factory system? Looking for info before I tear things down too far!

    I'm installing a Rockville power sub under the driver seat.

    TIA

    I have a 2017 with an aftermarket Sony receiver. I just ordered a Cerwin Vega under the seat powered subwoofer. wanted to save storage space and still get a better sound. Due in next week. Good luck!
