Default adding powered sub

Long-time lurker - First time poster now today because my problem is stupid im sure
2021 A4 S-line - B&O sound
Got a steal of a deal on a JBL BassPro SL as I wait for delivery I went ahead and began prepping the car by getting the pillar trim and rear deck off. Not replacing oem sub just needed access to the connections to add my pigtail. Anyways amazon delay delivery so I hooked the connections (1 sub 2 speakers) back up to enjoy tunes until the equipment arrived aaaand Nothing...... No Sound from anything in the rear deck!?!

All I did was unhook speaker connections and removed trim, is there some MMI reset? - did I fail to unhook power/fuse? Man as kids we would toss all kinds of speakers in cars and just hook up red and black with a double box of 12s on a tiny amp wired through the cabin what gives in these new age cars? What did I miss

Yeah these cars are not like putting a stereo in an older Toyota, lol. Try the MMI reset by holding volume **** down about 10 seconds. Are you getting any sort of error on the VC?

nope no errors and only back deck not doors. I really only removed trim and connections I'm flabbergasted which is why it must be something stupid simple, I've had the car on/off and did the 10s hold. It was a Toyota
