Cool. Thanks again for all your help. I started my build thread today. Hopefully it goes smooth.

What is this solid piece that is sitting on top of the new speaker? Was it included with the speaker purchase? If not, does anyone have a link for this item?

The speakers come like that from Focal, the ones I have have them too.

This week I took out the Focal TNF tweeter from the dash and mounted up a pair of 2.5 midrange speakers that have a decent frequency curve from 700 to 20K. The off axis response does the normal stuff at around 4K but I was planing on wedging both the 2.5 and the tweeter in the same spot.

I will say, after a quick tune using REW and a house curve that suites a no tweeter application I'm quite impressed with the sound of just the 2.5 only, no tweeter.

Right now:
Focal 6.5 Flax (Doors) - BP 24db LW 80-700 Hz
2.5 Mid-Tweet (Dash) - HP 24db LW 700-20K Hz
SUB - JL12Tw3 - LP 24db LW 80 Hz (Ported and tuned to 34Hz)

As a 68-year-old guy that has put way too much money into car stereo starting in 1970, I can't justify a huge expense for upgrading the horrible unit that comes from the factory.
Can anyone recommend the best speakers to plug in the front, rear, and sub? No amp this time.

Thanks in advance.

There is no best speakers when comes to sound. It's more of a personal taste and the type of music you listen to. I would just stick with the brands I like and find the speaker model that fits.
Most people here just change the dash speakers makes a huge difference. I changed the front door speakers as well, the difference not as big as the dash but noticeable.
I don't think the stock amp can push any decent sub.

To update this post I've finally settled on this:
JL 4 Channel (Bridged) - Doors
JL 5 Channel (1,2) - Morell Tweeter (Dash)
(3,4) - Morell Midrange (Dash)
(5) - Sub

You know, I replaced all my factory door speakers with the stuff from my previous ride. As luck would have it my Scion doors and my NX doors are similar shapes, and took some of the sound deadening from my Scion and made it fit onto the Nx. Bass response was increased, now I’m getting itchy and want to add my amplifier to the system as well as tweeters into the a-pillars and replace the front corner dash speakers with the remaining speaker from my Scion. I’d like to use the factory amp for the rear doors and maybe center channel. But use my amp for the front doors , corner dash and tweeters, that I’ll be using. And eventually try to build a sub box under the rear seat for my 2 8 inch woofers, and sub amp.

It sounds like you did not use a harness, and just used the factory wiring to feed your FiX82, correct?

If I am understanding this correctly, I should cut the wires for the front door speakers, and feed one side into the FiX82. Then after all the processing and amps, I'll run wire from the outputs of the amps to the other end of the wire that was cut, for the purpose of using the factory wiring with aftermarket amplifiers?

I have wires ran for new tweeters already, but am hopin to amplify the dash corners and center dash as well as I'm running AudioFrog's in the corners and a Hertz Milli Legend in the center. Front Doors are Focal ISU 200 components.

I've got a sub that I've been using for awhile but all I did for that was tap the sub wires on the amp harness, and feed that to a Kicker KISLOC2, which feed the AudioControl ACM300.1 sub amp. Now I'm hoping to have this sub processed throug the FiX82 and TwK D8 as well as front cabin speakers since they have all been replaced.

I have no clue what factory speakers are in the 2024 IS350 F Sport plus I have no idea what factory integration your have planned, I would need lots more details.
