Jeep Wrangler audio issue

Long shot here but had no luck on Jeep forums or with Crutchfield. My son has a 2015 wrangler jku with the factory Alpine system. He wanted to update to a radio that had CarPlay and other modern features. Ordered the new radio, the idatalink and harnesses through Crutchfield and everything works except for the factory sub. I’ve spent over 8 hours with tech support and we’ve changed all of the components 3 times and end in the same result of everything works but the sub. Anybody dealt with this before or have any thoughts? Almost at the point of ripping everything out and just putting the stock radio back in.

Do you have any amps in the picture or does the head unit power everything? I would expect the sub needs its own amplification.

Yes, that setup was an upgrade and it has a factory amp (i believe it’s a 2 channel). The amp powers all the speakers and the sub. The speakers work great, just nothing out of the sub. Tried every setting, switch, etc and can’t get it to work. I put the factory radio back in and it works great. Apparently the way Jeep setup this system is almost proprietary.

Can you play the sub on the regular speaker outputs (or are they pre-amp outputs and the sub is powered by it's own amp)?
Have you tested everything with a multimeter?
This isn't possible. To power "all the speakers and the sub" it would have to be 5 channels at a minimum.
ETA: Looks like the sub has it's own amp. Is the head unit sending a signal to switch on 12v power to the amp?

Either that, or check if you need an auxiliary power wire to the amp. If the new unit isn't sending power, but is sending a signal for the music, you may need to tap into the battery with a power cable directly to the amp. Or use this as a chance to upgrade.

How many ducks are blocking your speakers?
