Yes, roof / floors / rear inner wheel arches are all on the to-do list. Already have the materials, just need the time…

Just completed the dB test, before & after sound deadening all the doors and rear lift gate.
I’m going to tell you here before I post the next video on my channel since you guys have been so patient.
The dB levels dropped -1.8dB bringing the total measured level to 65.3 dB. It was previously 67.1 after doing the hood & fenders, and 79.2 at the start of all this.

Oh yea, the audio quality has improved immensely. I’m driving around the city at volume 5 and highway at volume 10. It’s plenty loud at those settings with the JBL package.

Rear door video is live!
FYI one of the 5 clips for the fender liner cannot be removed on the 26 LC. I’m not sure if they made a small change but I can’t access the squeeze clips. I know you were able to remove all 5 somehow from your video but no clue how I’d access the back. Planning to just screw the bolt over the liner and it should be fine.

Bummer! Worst case, drill it out and install a new one after the liner is back on.
i'm planning to let the washer on the bolt hold the liner in. worst case scenario ill drill out the plug like you mentioned.
Props to you Gio on the amount of work that goes into this. I did 80% of what you did on the front 2 doors and I was wiped. Also tired of scraping my hands on the bare metal constantly. Planning to do the rear hatch this weekend with some light mods…

Thank you! It is super time consuming and tiring for sure, but the end results are totally worth it.
I’m now working up the courage to start disassembling the entire interior. I think I may take a few days off work to knock it all out in one shot.

i'm down to around 64-65 db on the highway with the fenders, windshield, two front doors, and the GX 550 windows in. i haven't added the windshield strips quite yet but that's where i noticed most of the noise coming in on the highway.

Just curious in all this. Did you look at LC Peak? Like the people passing you that make noise? Or different road types? I’m finding a 7db difference between asphalt and concrete.
No, mine wasn't super scientific. I used a decibel measuring app on my phone once i got up to speed and had my passenger hold it in between the passenger and driver around ear level. it gave me 64-66 while going around 70 mph on the highway. i measured again on street driving and i was around 50 db.

Looking back on my tests the LC Peak stock was 106.4dB and now after a few phases of sound deadening it is 100.9db. All my tests are on concrete on the freeway.
That’s how I do it, and I try to average 1.5 minute test time.
Hi Gio - I am going to start on sound deadening my truck this weekend. At the 17:20 mark in your video on the front doors you hook up the door lock switchs to test to make sure the remote unlock is still opening. How did you remove the switches from the interior door card? I could not figure it out when I replaced my windows with Lexus windows.

I popped the switches off from the inside of the door panel when the panel was off the door. It has to be off the door in order to release the prongs by hand. I don't think you can safely pop the switches out with the door panel on.

I've still been working up the courage to start the massive interior sound deadening project 
but I have been doing some homework before I get started.
Found these photos of a well stripped down LC250 to see the inner structure and come up with a game plan...
