Hey all, new member here. My 2018 Tahoe LT has the bose speaker package. I'm trying to locate the factory sub, to tie in a line out converter for a sub amp. Everything i see online says it should be behing the rear drivers side panel where the jack is stored. I havent pulled off the hole panel, but i removed the cupholders, and the access door for the jack. I cant seem to locate any speakers back there. Im starting to wonder if i even have a sub at this point. Any help would be appreciated

 

My '11 with Bose the sub is inside the front console between the seats.
