I was reading through the instruction manual and noticed one of the included items says "AAMPPRO OEM Interface" so I assume this means it comes with the PAC AMP PRO...which explains how they are getting an RCA signal for their included amps. Based on this, I went ahead and pulled the trigger. It was $959 with the jeepbeach2021 discount. Shipping was free and there was no tax. I will post an update once it arrives, but it might be a couple weeks until I can find time to actually install it.
I have a problem.
Hope it's as good as MB Quart of old.
