Sharing my Dynamat project

And +100 to eliminating the foam smell. Clean it out of the carpets as best you can, but scrape away and replace this section.

I did a 100% interior Dynamat project back in 2012 and can definitely agree with what others have said: it didn't make the car quiet, by any means, but the effect of "Stuck a 20 gallon rubbermaid tub over my head and beat it with rubber mallets" was much less afterwards



FWIW, and you may find the same - I had to cut away sections between the seat track mounting posts, as it was just thick enough to interfere with the seat sliding.

Very cool, I think I suspected going in to it that it wasnt going to make the biggest difference in the world but it almost seems like it would be silly not to at this stage. Even it makes a tiny difference. I also cut out for the seat mounting just in case. Your dynamat job looks great

This was definitely a messy job scrapping away the residue of this section. I laid dynamat and also considering adding on top the thicker firewall type dampening. Is that what you did?

Yup! You know what made that foam removal SO easy for me was just soaking the foam down with the Dow Scrubbing Bubbles cleaner. The kind that foams up real high on contact. After about a half hour sitting, the foam and adhesive all just wiped away and it smelled great in there to boot.

I put down dynamat on the triangular section as you can see, as well as on the firewall. Then I bolted my amp to the firewall board from the other side (the wooden one, not the structural fiberglass) and put new carpet pad foam on the wooden board before re-covering it with the carpeting. I wanted to preserve some of the squooshiness.

I see your fuel shut off bottom right. Have you found that you use or need that? Also do you have a picture of your finished back panel, area behind seats?

I’m not sure what you mean by fuel shutoff - do you mean the battery switch? I use it all the time, it’s a fantastic help when working on the car!

As for the parcel shelf, sure thing - this is after the total electrical compartment rebuild, the amp is installed behind the backer board, all the dynamat is in and the speakers are all replaced. I don’t keep the net installed because it’s really annoying ��



If you’re curious what’s behind the board, here it is. I got pretty creative with this install and was really happy with the results.

Looks good man. Yeah it must be a battery kill. Good idea. You are thorough with the install. So to access your fuses for example you would remove the large grey panel, Then the black triangular piece to reveal fuses? I got the car semi taken apart so its interesting to see all the pieces for assembly.

Ah, mines no different than anyone else’s in that regard. You just lift that thin piece of carpet that lays across the shelf, then pop out the wooden triangle that covers the electrical compartment. Easy peasy

Thanks for sharing this. Very clean install. How does the section with the amplifier install? How did you address air flow around the amp? I thought about doing something similar to hide the amp behind the bulkhead carpet but was concerned about not getting enough airflow around the amp (thought about installing small cooling fans).

I deliberately bought a very expensive Class D amplifier (JBL XD400) that’s solid state and not prone to heat issues as a result to combat this. It’s not only smaller, but draws much less power and generates nearly zero heat as a result.

The board is just the stock parcel shelf back, so those wire loops at the bottom slot over the vertical black metal brackets, then the cargo net hooks secure it with screws from above.
