Cargo Area Carpet / Dynamat

[Lightweight]

I spent Saturday finishing a long overdue project. Since the Defender is a daily driver for me I wanted a little less noise from the rear cargo area, I researched a heap of options and came up with the Dynamat extreme underlay with high grade marine carpet over the top. I stripped the back out and gave it a thorough clean, then laid the Dynamat and then finished with the carpet. I am extremely happy with the result both from an aesthetic point and a noise reduction point, when a rock flung from the tyres into the wheel arch it sounded like a gun going off, now it is just a very slight ticking noise! And I can probably stop getting "dad, your car is noisy" each day when I drive Miss 4 to school.

The only issue I have is the very slight lump in the carpet from where each panel of Dynamat was overlaid, but I did follow the instructions.

Gday! looks a really nice job! I've got that on my "to-do" list, just wondering if you used any bonding agent, or did you mainly use fasteners? I'm considering using Scotch Velcro with self adhesive backing, so that I can quickly remove the carpet from the floor for cleaning/drying. The side walls could be bonded. I'm also looking at installing cargo rails onto the floor to aid in securing the carpet....

Anyway, certainly improves the sound deadning, great job, thanks for the photo's!

Hi Dave,

The Dynamat has a self adhesive backing on it and it is bloody sticky. On top of that I used commercial contact adhesive and then the fasteners are there from the seats, child restraints and the fasteners on the back seat floor around the edges, also there is some capping near the back door where high chance of lift would be. Some purists would say i have detracted from the easy hose out philosophy of the cargo area in the defender, this is why I used the best available marine carpet as it can be hosed out and will last for the life of the car. The noise reduction for me outweighs the disadvantage of the carpet.

Where abouts did you get your Dynamat from? I found some a ‘Strathfields car Stereo’ last time I was home, only place I’ve seen it in Oz and it was pretty pricey.

Good work!

This is what I did, and I'm really happy with the results. Key is also making sure there are no holes anywhere either.

I got a whole heap of velcro to stick the carpet down but was too lazy to install it. Don't think I'll bother now - it hasn't moved at all.

Top job mate.
A few questions.

Did you do the whole way through to the front seats? So under back seats also covered? The Dyno stuff, is it rolls of material or is it patterned for the defender? Can imagine a stanley knife was needed regardless?

Also where did you get it?

The Dynamat came from Ryda in Sydney somewhere, i ordered it online, and was $200 for 9 sheets, about 13 sheets are needed so if you can get the sheets in individual or smaller packs I assume you could save some money, I have also seen it on flebay and available from the US. It comes in all different shapes, but I have never seen templates for individual cars. It is pretty easy to apply, peel off the backing, stick down and roll with a vinyl rolling tool. It is very malleable.

>>Jimb,

I removed the back seats and all of the brackets and carpeted to the vertical panel behind the front/passenger seats. There are 8 or so bolts here that i wasn't keen to remove at this stage as they look like they hold the cabin to the tub and If I removed them I was worried that the tub would not realign correctly. Maybe someone here knows more??? I may get around to doing from there under the front seats one day.

Ill post pics when I do the front, after the new firewall us in.

It's really important to wear gloves when you handle dynamat.. it cuts like nothing else and you can't even feel it. I had no idea until I saw blood everywhere..

Thanks for the info gents. All good stuff.
I was just looking around when I spotted the Dynamat in Strathfield, being a Chip Foose fan I had to have a sticky. The guys there quoted me $300 plus for the large pack. I can't remember the exact price but it was over $300 and I can't remember the type of mat is was?
Now I'm a little bit more knowledgeable, I can research it properly.
Cheers

When you say $ 200 for 9 sheets , what is the size of the sheet?

My mate supplies the Avesco cars with a heat and noise shield stuff but I think it's pretty exxy.

I measured up at approx 9.0m2 to do from front firewall right through to rear
