OEM Subwoofer help..

[snapperhead4888]

I have been researching this and have had no luck with this question... I want to put the OEM subwoofer in my 2021 Ram 2500 Cummins with the basic speakers; I have upgraded the radio to the infotainment UBD Radio Uconnect 5 With an 8.4-inch Display, Including Wireless Apple CarPlay. The truck has the wiring for the OEM subwoofer, and under the dashboard, attached to the emergency brake lever, has the amp, which is part number 68402059AF. I connected the subwoofer and turned up the bass, but I got nothing out of it. I pulled fuse F71 and all the sound stopped coming out of the radio, so I am now at a loss of what to do or where to go next. Any help would be appreciated. Thank-you

Did you ever get this resolved? I have a 21 3500 with the amp on rhe parking brake release handle and want to add the stock sub to my system if possible

You may need AlfaOBD to enable the sub.
