Adding subwoofer to 2016 Suburban LT bose

Hey everyone, I know there's lots of posts about adding subs and amps but I'm having trouble finding the info I need for my situation. I have a 2016 Suburban LT with Bose option code UQA. I do not have a center speaker in the dash, I have front tweeters, front doors, rear doors, and possibly rear tweeters. It does not appear that I have a factory sub that I can tell.

I was planning to follow the instructions here to install my sub and amp using a line output converter.

2015 Tahoe LTZ aftermarket amp and sub install

Over the next few weeks I'll be putting a single 12' sub in a ported box that will fit behind the 3rd row seat. At this point everything has been ordered and the box came in today. I wanted to start a thread to document my journey and allow feedback/suggestion of those whose foot steps I'm...

My question is will tapping into the same wires on the amp harness get me a sub signal? or is mine going to be different due to the fact that my speaker setup is not the same?

Has anyone had experience with this mid level bose setup?

If you are remaining stock and just adding a sub woofer I would not recommend a "line converter" it will sound like trash and you will not have much if any base at all
what I would recommend is a audio control lc2, lc2i, etc or compatible bass restoration module.
reason being the bose system filters all the channels out HEAVILY. adding the module restores the bass signal and depending on the model also gives you a bass control knob.
it's well worth dropping a extra $70 for a bass module.
other than that you are ready to rock, the small factory sub is in the center console but it does practically nothing.
tap into the signal at the AMP in the rear drivers side compartment, easy to do the panel just pops off and walla everything is right there, just run your power wires as usual for the sub amp. the audio control should also give you a amp turn on signal.

I appreciate the input, I'm considering the lc2i or possibly doing the PAC harness that just plugs inline with the amp. I'm really looking for someone else with an LT like mine just to confirm a few details as this is not the same 10 speaker system as the ltz or Denali have.

the audio control is what I put in the wife's 2016, bose not the 10 speaker
tuned it and works pretty good for just adding a sub, the rest is all stock

@Doubeleive I have a question for you I have a 2003 suburban I recently purchased the guy before me put the g pack interface in it well I have four 12s that I had in my Tahoe I put them in my suburban now and with two amps powering the 12s I have a problem when I crank the gain up on the amp barely even at all it shuts the whole thing down I believe it's because from what I understand that the bose amp turns it off. how do I go about fixing that. when I say I have like 5,000 Watts I have about maybe 400 watts coming out of my amps right now because if I turn it up at all it it makes it just go silent it turns it all off. I'm trying to find the easiest route in the most effective route I don't really want to put it aftermarket amp in here to power all the door speakers because I just really rather not have to do that at the same time I want to have I want to have my Mac output that I can have because that's what I built 10 cubic square foot box for was to maximize every bit airspace so I can put to the speakers. But I have an aftermarket head unit it's an aftermarket Kenwood double DIN head unit and I have my RCA's coming off of the rear subwoofer output going to my subwoofer amps I've read a couple different things on how to bypass it but I don't want to bypass it and not have the door speakers have any power to them I don't know how that would work so I just need to know what I need to do and what I should do and if I have to put it aftermarket amp in here I mean I guess I have to do what I have to do
