Wow - interesting info. Trying to tap into the data bus to yank out the line level feed seems like a non-starter. I see aux input adapters and similar. Maybe one day we will have access to aftermarket DSP/Amps with such compatibility...

Keep on rockin'
you mean like the mObridge most150 amp
not sure if theyre actually out but they showed them awhile back
EDIT - WELL - Scratch that - no mobridge compatibility is listed for Lexus at the moment (I'm literally shedding tears about now!)
I already have an Alpine H800 DSP + RUX C800 I yanked from my deceased 2013 4Runner (along with a W910 Nav/DVD HU I can't use in the GX ) , but looking at the new Alpine 12-Channel 0850S DSP (with the dedicated controller and BT module) to allow more seamless integration with the factory HU. And also for its lossless Blue-tooth capabilities to bypass the stock system all together (stream lossless BT direct to DSP from iPhone/Android).
I actually use FM more than I'd like to admit lately as I hit my mid-life crisis (lol) - plus retaining Hands-Free phone integration + steering-wheel/radio control of volume and source selection is EXTREMELY appealing to me (without having to switch sources from BT to Analog HU via the downstream DSP's input control). My installs are ALWAYS of very high-caliber, and GUI user-interface is also a part of the big picture for me assuming audio quality is not sacrificed in the end.
I'm sure it's obvious to us audio-snobs out there, but the factory setup has seemingly un-defeatable "loudness" EQ built in (bass-boost at lower volumes). This is with factory audio leveling and "Surround" functions defeated in the settings. Is that "Loudness curve" in the radio (Pre-MOST bus), or in the amp (POST MOST distribution)? Other-words - would the "DA3 DSP PROFESSIONAL MOST" bypass the factory "loudness" volume curve? I strongly prefer a linear frequency response at all volumes...
Thanks for all of the valuable info I gleaned from this forum in the short time I've been here. It is greatly appreciated
Toodles for now

radio receiver itself has MO and MI. There's a loop with the display/nav. The amp also has both. like other bus stuff, they are all tied. seems to me that the dsp could actually be anywhere in the system. or even in multiple places. if i remember correctly, one of the diagrams shows multiple inputs (other system functions, like SW driven, not hardwire inputs) to the sound from many places (systems).
I wanted to ask: for the JL audio amplifier you used, where did you route your power cable from the amplifier to the battery/where did you go through at the firewall? And where did you mount the ground for the amplifier?
Thank you!
Looks like that is done for.... Do you have another place you go for this info. I would love to check out the differences between a 2010-19 vs a 2020&2021 all the way around.
It does tap into the L/R door speakers and dash speakers. I let the center channel pass through. The tap is post factory amp. I used a T harness so I didn't have to cut any factory wires incase I wanted to remove everything (PAC APH-TY02).
Here is a picture under the passenger seat:
And the sub I added under the driver seat:
hey. I just ordered this same sub. I’ve got a base model 2013 GX. I see you are in SC too. The harness doesn’t say it works for 2010-2013 but your amp looks the same. I’d love to chat more to figure out which speaker line you used for the kicker. I might add an amp down the road for my 4 door speakers. If you got some time to walk me through what you did. I’ll send you me contact info.
