Best bet for that amp is checking out the Stinger forum or another Kia/Hyundai car that uses a similar Bose-branded system (unsure of the lineup). As far as I know, the system is CAN bus. Bad news for anyone wanting to retain factory head units.
You’re gonna have multiple remote lines and power for all channels and inputs mixed in there so guessing pinouts won’t result in anything great. You’ll need a signal converter if you just want to splice for subs - and you’ll need the correct pinout for the Bose module. If subs are all you want, I always recommend Gladen/Mosconi equipment over everything.
Be advised that if your dealer finds a splice, they likely have every right to void warranty.
