I just found out that my childhood friend (yes, we use to hunt dinosaurs on the way to school together) owns Second Skin Audio. If anybody is interested I could talk to him about a discount code. His stuff is US made and his business is located in Tucson AZ.

Cool. SS makes some great stuff. I have it all over my 110.

" worth mentioning .dynamat does not use asphalt. Yes you can get sound proofing for a third of the cost but if you would prefer the truck not smell like a freshly paved road on a hot summer day than pay the extra money. if you (or often more importantly the wife) doesnt mind the smell than go for the cheap stuff"



I have used the McMaster Carr copy in 4 different rovers for almost 20 plus years. I covered 150K in my last one and never had a smell of asphalt, ever! That includes several long multi week trips in Moab. Dynamat is great stuff. I have just been in the manufacturing end of the world for way to long. It cost pennies to make and they charge a ton for what you get. If you have the money and don't mind paying full boat great. You will get a good product. If you see that they over charge for what you get, you have a less expensive alternative that is equally great. I have used Dynamat and the McMaster copy and if you took off the logo you would be hard pressed to tell the difference.

Cant comment on Mcmasters product but I can say the stuff from Home depot sucked. It smelled terrible and I couldn't get rid of it.. Perhaps you don't think Mcdonalds fries are salty. everyone has different tolerance.

I just ordered a gallon of Al's Heat and Noise Reducer. Its kinda like Lizard skin as it is a paint. Its purpose is to dampen the vibration of the panels. Then I'll be going with a Mass Load Vinyl to kill any sound waves that make it through. Or at least that is the grand idea. I have nothing in the 109 and even with noise canceling earphones I'm getting tired of the ridiculous noise on the interstate.

There is one hole I have to patch and then after that I'll paint down the HNR.

Thanks for the McMaster carr link. I'll see if they've got MLV as it is stupid expensive on Amazon.

Here is our code for 10% off orders of $200 or more.
SUPER10

The owners name is Ken and he is a super good guy. Hope this helps, I'm going to do my door with their product in the next week or two.
If you do order please let him know you are from the Defender Source and hopefully he will keep throwing discount codes our way.

On my way to implementing multiple sound proofing measures (thanks Ed), but made one small change that was huge: added a foam pad under the shift boot (PN: ETX500050). The decrease was so dramatic, I'm thinking about stuffing another one in there for good measure.

Didn't get a DB measure before the change, but sitting around 84 right now (200Tdi).

Interesting - Anything special about the foam or could one make his/her own?

Not that I can tell, but I'm no foam expert. I would think you could make your own, plenty of google images available. Knowing defender parts, you could probably make it better

I made one of these out of some thick scrap foam I had from some packing materials. It does make a noticeable difference in road noise, given you can see the road when it isn't in place. If I'm ever held at gun point and forced to pull that damn early 80's rubber single piece footwell/tunnel cover again (WAPITA) I will splurge and get the right one next time.

I will second this. I went this the other way. I removed it and there was so much noise I put it back.

I bought a roll of 1/2 inch rubber to make that exact thing! Addressing that spot really is key. Thanks for the pic.

ive always had it in - guess Nene Overland knew - and jeez it makes a difference. Also the bonnet matt one makes a big difference...

I do know the next thing is firewall (engine bulkhead side) deadening material for me to complete all you can do

Any details to provide on the application of the fatmat? Did you buy a particular thickness / kind (not sure if there are options there). Also did the self stick adhesive alone hold it upside down without issues?

Put Dynamat Hoodliner on the underside of my hood, it took the edge off on the highway. The Isuzu is still loud but you can tell it's a little better. It was only $50 off amazon. If I were to do it again I would put some Dynamat extreme under it first.

I've just done the rear tub, rear footwell, and front footwells on my 110. I used a box of Dynamat extreme, and two 18x36" pieces of generic sourced locally froma an audio store. The difference?

Dramatic.

Road noise is greatly reduced, so much that at 75mph you can have a conversation.

The plan is to get two more boxes, remove seats and seatbox carpet, and do those areas and inside the doors. I also plan to remove headliner and rear window trims, and use dynomat and their closed cell foam product for noise and heat defeat. The two products together should reduce condensation between headliner and roof, which is the killer of headliners.

I have sourced new headliner fasteners, as I do not want to get into this and have to half ass it if a few break. I am researching part numbers for seatbox carpet fasteners, and for door card fasteners.

I have also noted 2-3 water ingress areas in the tub, which I will seal from underneath once weather gets warmer. I did not dynomat over the tub floor seams, as I do not wish to trap water, so I ran about 1/4 from edges.

I also noted loose and missing fasteners in the front and rear floor panels. These will get addresses under the CPO warranty I got from LR Europe. It may be built like a tank, but a Russian tank at that.

Double layer. Nice idea.

I did dynamat plus hood liner. Made zero difference and the hood liner soaks up water like a sponge.

The factory foam that should be there on all these trucks btw, is about 1.5- 2" thick.
