Gang,
Got to work on a 2020 G23 today. The owner bought the boat with no tower speakers or amp so it only had one amp for the sub and cabin. We added another amp for the tower and speakers. The wiring is pretty straightforward.
These new amps do not have any switches or dials on the outside to configure them for zoning, bridging, etc. It's ALL done with the JL software. I downloaded that to a laptop and connected to the amp with a USB cable. At first, it is VERY confusing. There is a LOT of functionality here. Mostly we needed to map the inputs to the outputs to "tell" the amp what to do. This is much easier if you label everything. Label the low-level cables going into the amp. Label the speaker out wires. In the software, label them there as well. Having them labeled "Tower Starboard 1" is far easier than remembering that it's "Output 5" or something like that.
Once we had everything labeled and mapped, you just send the configuration to the amp. It takes effect immediately and we had them going. There is so much functionality here. You can set high and low pass filters on each channel individually. A full equalizer is built into the amp. You can bridge channels, set gains, reverse polarity on wires (I would not do this. I would fix the wires instead).
The software is free on the site and will run in simulation mode if you're not connected to an amp.
