LAST UPDATE: Super happy with how this turned out! There is a slight rattle on the rear window in heavy bass, but I've realized that with the rear seat folded down that goes away and sounds MUCH better anyway. Happy to answer any questions.


Just installed sound deadening in all 4 doors and swapped speakers while I was in there. Shout out to flaberdoopin for the videos of the disassembly. The first one took a bit longer than anticipated as the trim brackets Crutchfield sent were a wonky fit (ended up using the packaged screws but also Gorilla Glue to be sure). I mounted the speakers to the trim plates first, then installed the plate+speaker into factory holes. That said, I finished all four doors - sound material and speakers - in about 3.5 hours. The last door took maybe 30 minutes bc I was a pro by then.

The JL speakers definitely sound better than stock, but the sound deadener its absolutely worth the time invested. Check the video below and you'll see how much of a difference it made.

Next week I plan to install a Kicker hideaway 10 with the Sounds Good KEYLOC.

In case anyone's interested, here's the parts list I used [updated to include all parts and tools]:

Siless, first layer (see pic)

Siless, second layer - This one is probably twice the thickness and clearly made the biggest difference.

I only used half of each box to complete all 4 doors, so plan for leftover material unless you can find a smaller box / maybe pick up on marketplace. Honestly, the difference in sound and 'feel' of the doors opening/closing are substantial enough that I plan to do the headliner next week. Its a PIA to take down but with leftover material and seeing the difference it makes, its a no brainer for me.

Rollers - must use

Trim tools - these were cheap, and I snapped a couple, but they got the job done in the end.

Fronts - came with the harness and trim plates. Harness was plug and play.

Rears - same as above. The harnesses for the rears were a tad short, and thus a tight fit around the trim plate. If they were 2mm longer they'd be great.

Various parts and tools:

Ring terminals

Inline fuse (may not need)

Strippers

Distro block - splits power to KEYLOC and Sub

fuses

quality zip ties

Inline fuse (tucked under hood near battery, used double sided tape)

Loom for power wire under hood

Fish tape for wire pulling

Kicker KISL RCAs

Velcro tape to secure the KEYLOC to the truck floor (only need hook side, carpet holds it)

Power wire (this was easy to work with and seems to be of high quality)

Connectors

Heat Gun

Torx set (you'll need a larger one for the seat removal that I already had laying around)

Extension rods

ABS plastic sheets for the sub mount - this was not super easy to work with, but it came out ok and I'm glad I used it.

Egg crate for between the mount and rear cavity


I left the tweeters and center as stock. The stock amp seems to power these decently. I'm sure an upgraded amp would be awesome, but as of now I'm going to keep it. We'll see if the Kicker sub changes my mind.

Hope this is helpful to anyone considering doing the same mod.

REAR DOOR WITHOUT SOUND MATERIAL, FRONT FULLY INSTALLED. WOW.



______UPDATE:


Install complete. It was a beast for sure, but mostly bc I kept having to go back to the hardware store for more tools & parts. The Hideaway, KEYLOC, and 8AWG power cable I ended up running were all different gauges, so fitting everything together clean and tight was more difficult than expected. The Kicker hideaway harness uses fairly flimsy wiring, but so far thats my only complaint. The KEYLOC from Sounds Good was plug and play, true to their word. Harness was clean and wrapped nicely.

The Hideaway sub doesnt have RCA inputs so I had to splice the RCA out (from KEYLOC) into the factory Kicker harness. Again, different AWG, making for a tricky connection even with the Kicker add-on kit.

Overall though, I'm impressed with the sound quality for the price. Not regretting passing up the JL Stealthbox at all.

I made a custom mount using ABS for the sub, added some egg crate material behind. The back of the rear seats seems to keep everything pretty tightly pinched - no rattles, as I was expecting.

For the power distribution block and the KEYLOC mounting I just used the hook side of some velcro tape, which seems to hold well enough against the factory Ford carpet.

Hope this was helpful to the forum. Overall I think I spent around $1,100 or so for: Sound deadening material, JL speakers (4 doors), Kicker 10 Hideaway, distro. block, KEYLOC, various wires, parts, fuses, etc.

Well worth it. The time invested was significant, but if I had all the parts at the ready I'd estimate 12-15 hours. Pulling the trim, rolling the sound material, running the cables, removing & replacing rear seat...all that added more time than I had planned. Luckily I'm between jobs so I was able to chop it up across a few days.

When are you planning on installing the sub? Interested to hear how much of an improvement there is over stock. I'm considering the same Kicker sub. Thanks!!

Nice write up. Thinking about upgrading audio but starting with tweeters.

nice work. I needed that video on removing the door panel. I had my RR about 5 days and some dumb@$$ have me a door ding. Looks like it's right behind the pass door speaker.

Take it to a paintless dent repair shop - they might be able to sort it out in a few minutes for very little cost

My uncle retired from body work and used to do paintless repairs for local car dealerships. I was hoping he still had his stuff to hook me up. There was a x dent franchise near me but he closed and sold his stuff off, I bought his shop fan and a few tools.

Nice work!

I did something similar to mine , but I didn’t change any of my audio equipment, but did notice a substantial improvement in the sound quality of my stock audio systems just from the sound deadening. It’s an excellent upgrade For several reasons.

Do you think just using the "second" layer alone would work?

how much does it reduce wind noise at highway speed? People say they can hear wind noise or road hum or something when I'm doing CarPlay phone calls on the highway 75mph. The phone sounds good during stop and go and is pretty clear. But on the freeway they can hear the underlying background noise. I don't notice it much as a driver and in the cab, but phone picking it up.

Great read ! Subscribed to follow your next steps.

Can't wait to install deadening mats and get going on my audio upgrade project.

I had a Audison Forza M5.11 bit (DSP 5.1 amp) laying around. Going bonkers with replacing all speakers with Hertz Mille Pro, dual amplifiers, all active. I'll use the PAC AmpPRO AP4-FD32 to get clean optical signal.


Can i suggest another route for your solution ?

Instead of going with a powered sub, at a way better price than JL stealthbox, I think you could look at another option.

We are a couple of owners that are going the Stealthtech Ford Ranger sub box from Austrlia. You can fit a 10" sub in there. I'm going with a shallow Hertz MPS 250 S2 which is a pretty good value (you can go even cheaper) for the volume available. It will sound way better than a powered box behind the seat.

Hideaway 10 + KEYLOC/harness is about 700$ ?

Stealthtech box is about 150$, plus a Kicker 47KEY500.1 (500w rms at 1 ohm DSP AMP that combines the smart KEYLOC and a 500w amp) about 240$, plus a 175$ 10" 48CWRT102 (400w rms dual 2ohms version, so 1 ohm, would fit better with the DSP Amp that is stable at 1ohms). Total 565$, cheaper and it will sound wayyyyyy better! You still need that harness though (without the KEYLOC) so might be a wash.

Just put some butyl around that box and some polyfil in it.

Here's my box ready to go, waiting for parts to get in.

The sound deadening stuff is the most interesting thing in these posts. I like how quiet the truck is now and cant imagine it being even more quiet. I will have to try this stuff out. Thanks for the tap video, that really shows the difference

I did the door sound deadening project last year. Very satisfying job. I had the deadening material put under the headliner a couple months ago. Huge difference!

I agree they are not super loud where road noise is concerned , nothing like a Bronco .
There is nothing insulating the roof, and a moderate rain storm can sound more like hail storm without the dreading materials being added.

I liked it enough after doing the first RR, I immediately did my other RR, and was one of the top priority mods for Godzilla project RR that just got its sound deadened done a couple weeks ago.
