The mono thing was just because of the number of amplifier channels I had available at the time. I've since upgraded to a 12 channel amp and running rear fill in stereo.

That said, the device is set up to preferentially direct rear fill to the door speakers instead of the rear c pillar speakers due to their tiny size and inability to be replaced by anything aftermarket due to space constraints.

If you do end up buying and want to direct rear fill to the C pillars let me know and I'll make a modification to your unit so that it can do that. Not a problem.

Sorry for the slow response - I've been manufacturing harnesses for a large distributor order all weekend. Regrettably, I no longer have analog T-harnesses on my pipeline as I need to focus all my R&D energy into next-gen digital integration (which includes your 2026 Si).

Sorry for the bad news - the upside is that by September I will be fully focused on the A2B integration R&D once I get these orders processed. I have purchased some of the proprietary technology needed to reverse-engineer Honda's protocol and hope to be doing prototype testing by mid-Fall.

Hey at least A2B allows for daisy chaining and nodes... I wonder if that would allow cleaner subwoofer add-ons or not, or if whole system DSP would still be needed.

That would be very hard to do because the master A2B node has burnt-in registers of what nodes it expects to see when it wakes up. I think you'd have to reflash the master first before you can add anything that doesn't belong.

In the case of an integrator replacing a node (ie a factory amplifier) you are just fooling the system by replicating the address of the former OEM node.
