Yet another subwoofer amplifier install project! Any advice?

I will post some later. Nothing fancy for this DIY. Just clean and practical.
No, I did not replace the factory sub. This is a completely separate aftermarket install. An direct OEM replacement sub may exist. Resistance matched and same size, but I haven't seen one yet. Most folks are modifying their rear decks to fit their sub of choice AND powering it with aftermarket amp. That is one way to go.
I too did my own installs in the past. Unlike the installs of yesteryear, our stock Lexus head unit communicates to the OEM amp over MOST Bus. A special wire that sends audio AND command signals to the OEM amp. There are no "line level" signal wires to tap. Only MOST Bus going into the amp. The only wires you can tap will be high-wattage speaker level signals exiting the amp. And those signals will be crossed-over. Highs get highs. Mids get mids. Subs get lows. This makes good use of the OEM amp.
Folks tapping anything other than subwoofer are probably combining multiple channels via a DSP to restore a "full range" signal. This makes sense if you're doing a full system replacement. But less sense if you're just adding a sub.
Hopefully this helps you.
Does anyone have a definitive procedure that has been tested and WORKS perfectly?
I've read a lot of people debating over which wires to connect and what line processors to use to get optimal performance from the factory ML system.
I have 2 JL 12W1v2 speakers and a JL 500/1v2 and ready to install.
I use to install back in 99-2002 but I worked for a large company that basically got me all the info I needed for cases like this as well as the vehicles weren't quite as technologically advanced.
Looking for 1 tried and true way to install this system.
What parts I need and what tips work.
Thank you!

It all depends on what you want. I like my to feel my bass and for it to be clean. So he advised a sealed box (which i had before, but now customized to fit the trunk) and to face the cabin so the bass goes directly into the cabin. if you face it outwards, there's more rattling, which i'm not a fan of.

cant wait to get my w7 and 1000/1 i had from my previous car in my new gs 350. I hope it sounds good with stock headunit and the regular non upgraded factory speakers. Im still thinking if i should use the stock red carpeted JL box which is huge and ill lose alot of my trunk space but sounds very good in it or get a smaller not ported sealed box to save space. Its a 12" and te box is dam huge. And i dont even crank my amp half way. Maybe i should get a 10inch in a sealed box and sell mine or find a local trade. Getting the mod bug started. Tints getting it done monday. Hot wired V1 radar already and subs next than some intake and exhaust setup than some window tire wheel setup at 16~17 inch and have some fun on te snow in the AWD. Cant wait. Car is sooo smooth. Good thing i choose the gs350. Still has the new car smell and only been a month loll.

Is tahat a w7 ? What inch? Im trying to get my w7 inside my trunk. I have the OEM box for the 12 inch. Did u lose alot of trunk space facing that inside the car? How does it sound with the OEM speakers? Do u have the upgraded speakers from lexus or just the stock speakers?
Nice setup.

I am asking because I have an appointment to install a Kicker 11PES10C powered subwoofer on July 1st. I like it for its quick disconnect, self-powered, small footprint, mounting kit, and great reviews. But - when I look at the design shape it makes sense for me to mount it against the back seat and have it facing the rear (towards the trunk).
I'm no bass head so I will probably adjust the bass out of the factory speakers (to stop door speakers from rattling) and adjust the gain on the sub just up to the point that you can start feeling the bass. I suppose I can always go back for the dynamat option if it rattles too much.

Does the GS350 trunk rattle more than a typical car? That would seem surprising.
