Sound Deadener - Before & After Comparison 

Phteven Phtuart thanks for the feedback! Definitely a noticeable drop in road noise that’s for sure!

From memory every 3 dB is a 50% reduction in energy so it’s heaps!

3dB is double, or half. So 5dB is 3x

5dB is a healthy drop. Would add lots of comfort.

Thanks mate. I’ll have a suss on the 3M door kits, might be worth it!

Thanks David, really happy with it all! Glad you liked the vid. Cheers

So much more solid

Thanks mate, tried to get is as accurate as a amateur can with so many variables when measuring noise! Thanks for watching!

Very loud vehicles with thin panels; plus when you add bar-work, loud exhaust and roofrack that creates huge amounts of wind noise it becomes excessive!

razbarb thanks mate, the head unit is from VMS, who do navigation GPS software. I wouldn’t buy it again though. Probably get one of the next Kenwood headunits witg apple car play or something.

Thanks mate, glad someone was able to make use of it! I’m super happy with the effects of mine! Cheers

Pleasure hope it helped

haha Yeah thats it mate! Luckily, you shouldn't lose any V8 rumble, but even if you do slightly; it's worth it to cut out some of the road noise for sure! Let me know how you get on!

BruceTheSillyGoose $150 per door near my house in Atlanta, looking to do it my self

mass = weight tho...

Thanks for the question. I don’t really have any measurable data in regards to temperatures. I think the dark tint plays a big part in keeping the cab cool in summer. I definitely noticed a different in temperature coming from the trans-tunnel and with less heat emanating from around the gearstick into the foot wells. I guess adding any extra insulation would help with temperature retention, but I find the aircon unit in the landcruiser very efficient in all conditions anyway.

@@4wdAdventure well I went ahead and did it in my floors, doors and roof as well and i can tell from owning so many jeeps that it holds heat a lot more now than it ever did before and that the heat from the trans tunnel is now hardly there

Awesome!!! Glad to hear!! Thanks for the reply

@@4wdAdventure thanks for havin the confidence to make the video my man

Thanks mate. No noticeable difference, the aircon in my 76 is really good so it’s hard to tell. The biggest improvement for temperatures was dark tint for me!

Thanks for the educational comment! It’s a massive drop, I found it made a huge difference. It was the best measurements I could take using a phone under similar circumstances from the multiple test drives. Would be good to have been able to measure it with a calibrated instrument

gary tardiff It Is a big difference when you put one, two or three layers

What did you put in? From my experience foam mats lower db more than bitumen stuff.

Thanks mate

Yeah you use the roller to go over everything to press it down and make a good seal

Exactly 18kg - 6kg per pack

Wytch Hunter it’s a custom 4” stainless steel snorkel but powder coated matte black. Got it from CAM Fabrications. Found them on Facebook.

total weight for my cruiser was around 18kg

I was only talking the short time while it was being filmed. The sound meter was on the whole drive at the same speed and driving conditions and that was all being recorded too. Obviously never going to get perfect conditions for audio recording or a decimal point accurate reading on sound difference; was just trying to give everyone a rough ball park figure of acoustic improvement

Haha dogo was absolutely no help at all!

Cheers for the feedback mate!

Thanks for the message mate, thought it was worth a shot to try the comparison

Thanks mate. Glad I could help. Cheers for the feedback

Yeah nice one mate! I didn't even think about doing that! Do you have a GXL or a workmate? You could literally just keep going if you could afford to buy heaps of boxes haha. I totally reckon the three boxes I put in are worth it though!

Defo worth it mate!!!! I have a 2014 GXL, you can basically stick your fingers up between the inside body and the door as you drive and feel the door flexing. I did try some Ebay door trim that was sorta of shaped like a "D" if you can imagine it (hard to explain) to see if that would work when the door was closed but had no luck so through doing some investigating I see some people have yanked on the top of the door and bent it in and had success. Windows would have to be down and it would only have to be a slight adjustment but seems like it makes sense to me :) Like you said, you don't want to add to much weight so doing the doors alone is a big improvement over standard!

Thanks mate

I wish we had a few of yours here too! Love the big trucks

Hey mate, sorry about the late reply - I missed this comment! Interesting! Would definitely be an good thing to compare; I think it’s made the whole shell of the cruiser a lot more “deadened” but the improved listenability to music in general is GREAT; solely from having significantly less road noise inside the cab and not having to drown the road noise out by turning the stereo up. Can now actually hear the music a lot better without having to crank it up if that makes sense!

@@4wdAdventure it does. Thanks for the reply buddy.

Ray Bush haha sorry for costing you more money!! The list never ends!!!

Yea Im hearing you mate

Hey mate thanks for the comment - I didn’t think about that one! It’s one of those things that you could just keep going with, I am happy with the dampening effect that has been achieved so far. If I was building again I would do the whole firewall as well.

Nah the engine bay on the cruiser is so jam packed it’s almost inaccessible. It would be possible, but I never looked into it!

Thanks Oscar, I have 2x Sony 6x9 speakers in the wagon, 2x Sony 6” speakers in the rear doors, 2x Sony 6” speakers in the front doors, 2x Sony 4” speakers in the dash and a 10” MTX sub in wedge box (to suit the angle of the rear bench seat in the back). I have rewired all the speakers with new thicker gauge speakers cable. All 4 door speakers and the sub are running off a 500w Sony amp under the back seat powered off the ignition. And the rear 6x9s and dash 4” speakers are powered from the headunit - this is so I can have music playing while the car isn’t running and I’m not worried about extra speakers/sub and amp draining the battery. The headunit is a VMS in dash GPS which fits the space. I would recommend getting a newer unit with Apple CarPlay support and just using google maps through your device. The VMS is old technology now. Hope that’s helps!!

Awesome mate! Did you buy the Troopy kit from CarBuilders or are you building your own kit?

About $500 all up I think!

You have to be kidding...

@@enterBJ40 You have got to be kidding. Everyone loves an old toyota off roader. You gay bro?

@@4wdAdventure thanks chich!!! They look great

One more question mate, what offset are you running. -5 or -50. 16 X 8 yeah?

16x8 yup, but running 0 offset all round
