Sound deadening/insulating 3rd gen Tacoma

So I recently finished sound deadening and insulating the floor and back wall of my 2019 TRD sport m/t and figured I would share some pics of the project. I also installed an alpine mrv-m500 amp for the JL audio stealthbox I just ordered. Im not good at writing detailed posts but if anyone is thinking of undergoing this project I’m happy to answer any questions. I’ve definitely learned a few things in the process.

 

Solid work man. Looks really well done, and I'll bet that thing is whisper quiet now.

 

So anecdotally does it seem a lot quieter? I feel like my 2017 makes an inordinate amount of noise for a vehicle made post-2010 (rather arbitrary year).

 

I would love to have that done, but fuck it's a lot of work!

 

Hell, if I tried that I’d have enough leftover parts after putting it back together I could sell some

 

I also wonder if it is worth the work and makes a "night and day" type difference. If so I would tackle the job because my 2018 is ridiculous as far as interior noise goes. Coming from my 2011 grand cherokee overland edition it is like driving my old '88 civic again. Unreasonably loud inside the truck.

 

Been wanting to do the back wall in mine, just haven't found the time yet.

 

I have always found it really doesn’t make a huge difference in road noise. Great for reducing vibrations, but not so much for road noise. You will also hear more wind noise from the windows once you deaden the floor.

 

That's a lot of work, looks like you really took your time and did it right. You didn't mention the before and AFTER results, so if you can pass on any thoughts we'd love to hear them (pun intended).

 

Thanks for kudos fellas. So the main reason I did it was to try and block some of the drone from mbrp catback exhaust i put in last year. My first project when I bought this truck was replacing all 6 speakers. I also put a little bit of sound deadening in the doors just behind the speakers. The result was great but when I put the exhaust on it kinda over powered the speakers. Now with the sound deadening/insulation I’ve feel like I’ve definitely got some more clarity and volume out of my speakers. You can still hear the exhaust but I feel it’s not a completion between the 2 anymore. I mean, why put on an after market exhaust if you don’t wanna hear it. Lol. Overall I’m happy with the outcome but yeah, it was a lot of work. 2 full days of daylight to be exact. I’m gonna to go back and the doors the right way soon with both materials. I feel like it equalize the road noise as well help with insulation perks. If I didn’t specifically answer anyone’s questions feel free to ask directly.

 

Did you happen to take before/after decibel readings from the drivers seat on a identical stretch of road, same speed?

 

I did not, but I traveled the same routes I usually do since I did the install and it has made a difference. This will not make your cab completely sound proof but will definitely make your speakers sound better and take away some road/exhaust noise. I’m sorry I can’t provide you with that exact info.

 

How many square feet did it take to do the floor and the back wall?

 

@Captainsuperrad
Nice work OP, hope it was worth it. Where did you get the shift boot from? Yours is the first I've seen. I can't stand the leather one.

 

God that's a lot of work. I did mat in all of my doors and foam behind the speakers, mat on the interior side of the doors, and mat and foam on the back wall in an effort to reduce road noise. I'm not sure it helped bc it was shortly after I added a roof rack and noisy tires. I will probably do the underside of the roof and stop there. Sliced the crap out of my fingers doing it without gloves on the first day.

 

Nice MDFM31! Yeah, I collected quite a few scratches from the noico myself. Lol. The sounds deadening doesn’t really help block the outside noise that much it’s more to dampen the noise made by the vehicle. The sound insulation is the one that provides a barrier from external noise. If you do the roof please post some pics I’m a little hesitant to do mine do to the sunroof.

 

@1taco2motos

Overall I’m happy with it and I can certainly tell a difference. That is the factory shift boot, it doesn’t have the leather on it because I had to remove it with the rest of the center console.

 

Surprised someone has not made a spray on sound reduction product

 

Lol, thanks.
After I wrote that I thought, "oh wait, that's probably underneath the leather"...DOH!

 

Nice job! Since you’re still running the factory deck, where did you tap your remote wire for the amp?
