@PATS4LIFE Yeah! That's exactly what I'm looking for. No indication that particular one is compatible with a 2018, though :/

I love my maxima. I got in for $4k nearly 10 years ago. It's always been easy to work on because I just threw an after market head unit in it. Currently 4 amped 6" speakers and 2 12" w a 500watt rms amp. I'm planning on keeping the sub amp and getting a single 500 watt sub (I figure if I'm getting a grown up car, I might as well see what having a trunk is like for a change I might hold on to the 4ch amp and think about swapping the speakers out later but for now my goal is adding a sub with all stock everything. I've come to terms with the fact that I'll probably just be tapping the rear speakers to run to that AudioControl LC2i. I really wish I could find an adapter that sits between the harness and the head unit to do it but if I have to physically tap them, I guess it is what it is. I wish there was some sort of crash course on OEM head units. Like - are they the same across all models in the same generation? Or are the empreza head units wired completely different from the Legacy. I'm not having much luck finding diagrams or anything :/ I guess all I need to know are the rear LR speaker colors on the harness so I can tap them.

Thanks @KJS2023. That's inspiring. I see that Maxima too; I'm currently driving an '01 haha.

I've decided on a 2017-2019 Subaru 3.6R limited and I'm shopping around. I've been doing some research on installing aftermarket subs. I've always had subs in my car and done my own installs but I've never done an install with a stock head unit so this is a little new for me. My understanding is that I'll need to tap the rear speaker outputs and run them to a line output converter like this https://www.crutchfield.com/p_161LC2IB/AudioControl-LC2i-Black.html I'd like to do this without cutting anything - ideally with an adapter like this https://www.autoharnesshouse.com/82191_info.html if possible. Only, I haven't been able to find a harness adapter that specifically says it's compatible with the 2017/18 legacies. I see a lot for the 2015/16 models but I'm not clear on what the differences are on the back of the head units. Some pictures might help. It would also be nice to know if anyone else has done this and get some reassurance I'm on the right path. Aside from getting that sub out, the rest should just a matter of powering the amp and wiring the subs which is pretty standard.
