2023 audio upgrade JBL

I am working on an audio upgrade for my 2023 Taco using https://axxessinterfaces.com/product/AXDSPX-TY3. Looking at adding a 10” sub behind passenger seat. Replacing all other speakers with new. And adding a 5 channel amp. Has wondering if anyone has experience with this type of upgrade to the JBL system?

 

That part is for the non-JBL system

 

Actually, This is the one I have

 

Axxess module with DSP installed behind stereo. All power wiring remote turn on and rca cables have been installed to the amp location under the drivers seat. I will post pictures as the installation continues.

 

What amp is going under the seat?

 

Kenwood Excelon 802.5

 

Installed a speed wire and a subwoofer wire between amp location under drivers seat and new subwoofer location. Probably going to take a few days off due to waiting on new rear door adapters. Sonic missed the adapter part of my order. I am doing a similar install to my son’s 2016 Tacoma and that begins with a new head unit at Christmas.
