How Much Dynamat For Whole Car – The main appeal of a brand new car is often attributed to the things that wear out the fastest. In terms of appearance, these are usually high-contrast parts such as the headlights and exterior plastic exposed to the sun. For sound, a sense that is often overlooked in this context, it is attributed to the isolation of internal noises and the elimination of noises from the outside. As cars age, the walls, gaskets and door frames that filter out unwanted noise begin to weaken and wear out. This leads to a sip of road noise that increases the longer you keep your vehicle. However, if applied correctly, sound deadening material can actually make your car
New again. My sales pitch for Dynamite was, “You have no idea how much you want it until you already have it.” This is actually the holy grail of car acoustics. This post goes over everything you need to know about adding noise to your car, focusing on my B7 Audi A4. Muting the sound serves three purposes; Keep outside sounds out, keep inside sounds out, and reduce vibrations and vibrations inside and outside. The downside is that a well-dimmed material means added weight; Fifteen pounds for the doors alone, to be exact. If you’re the type to rip out back seats, tire cards and doors for race week, this isn’t for you. For casual racers who don’t care about their quarter mile time since the finish line is the grocery store, read on.

When it comes to choosing a product, it becomes an equation of budget, surface area and diminishing returns. I mean, how much are you willing to spend to squeeze the last few decibels out of this app? If your budget is unlimited, go with Dynamite. It is by far the best, as the app is often called

Your car Indeed, turning off the sound is as dynamite as copying newspapers for xerox. My budget is not unlimited, however, so I bought Noiko sheets. My thinking was that I would rather spend the same amount of money and cover double the surface area because I believe it would have a much higher return than less surface area of the better product. The phrase “a little dynamite goes a long way” may be true, but I argue that “a lot of dynamite will go a long way”.
A sound deadening material is often mistaken for a shield against outside noise. It should be more accurately thought of as a sound absorber, which attaches to the surface to reduce the ability of the surface to vibrate. Imagine an empty can sitting on the table. Now imagine flicking it with your finger and the
It does later. Now imagine holding the can firmly in your hand and giving it the same squeeze. Where before it rang and rang, now it emits only a short
. The same principle is applied to the noise of your vehicle. The carbon steel sheet that makes up the outer body of your door acts just like an empty can. Thick tar, supported by aluminum, which together makes the material a sound barrier, works the same way your hand works around the empty can. Instead of trying to cover all the spaces in an attempt to block out the noise, try to find spaces in your body and in your door frame that you can turn to

. Literally, if you tap a piece of metal and you hear a low clang, apply something to it or around it. Most luxury vehicles already offer a light dressing of rubber on the door body to absorb road noise, but this also degrades over time, hardening with the hot and cold cycles until it sets completely. If your vehicle is more than five years old, it has seen thousands of hot and cold cycles, so it is probably safe to assume that your factory muffler is cured and therefore less effective if not completely useless.
In this DIY we’re focusing on the doors, but if you have an open car (ie hatchback, station wagon, SUV) or other side panels, that’s worth doing too.
Then, remove the speaker housing completely. Then screw the control unit (three screws – top, side, bottom) and gently let it hang. Now carefully remove the strip of metal tape at the top of the foam liner, then the foam liner itself. We will reapply the foam piece, so try not to damage it too much. Peel off the factory sealing string. At the end of this step, all four doors should be bare metal. Note: On titanium trims and maybe some others, there will be one or two cube shaped plastic pieces. The purpose of these is to provide an airtight seal, but, as you can see, they have probably hardened and no longer serve a purpose. If you have them, remove them. We will replace them with a much stronger material.
The next step is to thoroughly clean the inside of the doors with a cleaning solvent. The tar from the dynamite will need a clean surface underneath to ensure a tight seal. Check out the pictures below to see where you apply your sound suppressant.

First we will focus on the door body (the flat part behind the frame), as this is the first line of defense against road noise. Start by laying out your dynamite and cutting it in such a way that it covers as much surface area as possible (red dashed line). Once this is complete, cut it into smaller pieces that will more easily fit through the holes in the door frame (pink dashed line).
After cutting the pieces, apply them to the inner panel and vigorously press the roller into the material. Many sound tanks have ridges that let you know you’re rolling when the ridges flatten. Here is an example of this application:
After you have dynamized all four door bodies, turn your attention to the frame. Tap your knuckles on the metal to find such spots
And again they started applying material aggressively to the places, using the same technique as seen in the video above. Where you find rounded edges inside that the rolling tool is not enough, use a tennis ball. Below is a heatmap of where I found the most ringtones:

The last step is to permanently plug the holes in the door frame. Something to consider about this step is that anyone who needs to fix the window, track or wire loom in the future will need to cut the sheet of dynamite. Below are the 2-3 holes we will plug. Green is recommended, blue is optional.
An optional step at this stage is to cut the matching recesses of the black foam door insert we removed earlier, as the holes where the recesses were placed close up. In order to let the surface material stick to it, start placing overlapping strips of automotive repair tape inside the holes.
Next, cut and apply your healthy silencing agent. Be careful not to trap air between the tape and the tar. Repeat this process for all the holes you want to plug.
Finally, in preparation for reassembly, draw a line along the track of the foam door insert and let it rest until it is tacky.

Then, remember to slide the handle hook through the hole, re-gluing it to the door frame. Then screw in the speakers and control units.
Replace any door latches that were damaged during removal, and reinstall the door cards and trim pieces, then you’re good to go! In September, I went to St. George, Utah for the Scion XB. It’s about a 300 mile drive. While I was there, a 16 year old girl left and barely missed my CSB, but hit the small trailer I was towing right through. The damage was extensive enough that I had to leave the trailer behind for a week while I picked up a new axle home in the SLC. Two trips a week to St. George and back made me realize something: at 80 mph, the XB is very noisy inside. So I ordered two boxes of dynamite and got to work.
There are different levels at which Dynamat can be installed. You can cover the floor, doors, roof, firewall, underside of hood and trunk, etc… I bought two bulk packs from Amazon.com. This is enough to cover the entire floor panel, the inside of all the doors, the inside of the quarter panels and the inside of the rear hatch on the CSB. (With some spare sheets.)
The internals were removed, I started sticking dynamite to everything. I quickly found that trying to use full sheets (about 18″ x 36″) was very difficult. My recommendation is to cut them into smaller pieces that fit the dimensions of the area you are trying to cover. This is especially true inside the doors. To make the doors, I carefully peeled off the plastic covers, cleaned the inside surface and reached, trimmed and squeezed the dynamite until they were completely
