Really appreciate the tips here. The first system I put into a car, I just did basic H/U and speakers with no sound deadening. But I decided to do off-brand sound deadening on this next rig. Definitely some good pointers in this video. Thanks!
I highly recommend using brake cleaner to prep the surface! I just sound proofed a 20 year old car with lots of grime on the metal panels and it went right off with no scrubbing effort.
Always loved my 2010 Acura TSX V-6 Tech Package, but wanted to make it "quieter". Had entire car done professionally, and it cost me about 2500 dollars. Was it worth it? Yes. Each of the speakers sound totally better, clearer, cleaner, and accurate. The sub goes down to advertised specs, and the entire car is one fine speaker cabinet now. At 80 mph, I can hear the music as well as at 45 mph, and the volume can be turned lower and still sound great. Highs, lows, mids, everything is clear now. Any waste of coin by covering every possible surface, including roof, floor, trunk and hood? Well, maybe. But I have no regrets. If I ever buy another really neat car or restore a classic, Dynamat will be part of the process. This is an excellent vid, Anthony. You give a lot of great information in a short amount of time.
Thanks for your comment! It one of those items, once you've installed it in one car, you want all your vehicles to have it. I tell people I can talk about it all day, but until you try it, you have no idea how much better your vehicle is with sound deadening.
Hey guys. I'm a proud owner a 2jz Toyota Altezza here in New Zealand. Dynamat is definitely worth the extra money in advancing audio sound. I personally stripped my car and added Dynamat to the door panels, roof, floor, boot and rear parcel dash. After installation i found rattling heard on the outside of the car was not as severe and tinny sounding, road noise is eliminated more, my bass from my sound system seems deeper and i found the car is always warm even without the heater on a cold day. The big feature for me was the fact that during a soundoff contest i gained an extra 1.2decibels with same song, same head unit settings, same volume etc making my best of 137.6 decibels. That may not sound like much to some people but for my daily driven im proud haha
Great video and still relevant today. Explaining that it reduces resonance is spot on. I've put Dynamat in every car I've owned since I'm a huge audiophile. And a few times when I sold or traded my vehicle, I've gotten compliments from some people noticing it was much quieter in the cab. Dynamat isn't a miracle product but it will reduce the noise pollution from very specific spots in your cab. The more you spend the better it will work. Layering different materials is key. Knowing where the sounds come from can help you buy the product you need effectively saving on cost of material. Most sounds come from the engine, underneath the car (the floor), Fender wells (tires), and trunk. Putting dampening material on your doors is the easiest part of the process but the least effective. Though it will improve the sound from your speakers the most. Something that isn't mentioned in the video, Mass loaded vinyl. Mass loaded vinyl can significantly reduce sound frequencies between the Mid to High range. Low end noises are the hardest to dampen. Dynapad does reduce low end frequencies by design. MLV has different weights of material starting from .75. lbs to 2lbs. The higher the weight the more dense the material, the more it filters out certain frequencies. You will never make the cabin luxury vehicle quiet but using these materials will improve your quality of life in your car while enhancing your sound system acoustics. Dynamat = Reduced Resonance and some high frequency noise Dynapad = Reduces low end frequency road noise and acts as a heat shield. Dynaliner = Reduces temperature and some high frequency road noise and reduces in cabin noises from reflecting (softened reflection). Dynaliner is placed on top of dynamat. (in combination) MLV = Mass loaded Vinyl = Reduces mid to high frequency sounds improving your cabin acoustics significantly. Expensive Want a quieter car? Don't buy or build a race car and expect dynmat to dampen every sound. A lot of it depends on how well your doors seal or the tires you use and the shocks you ride on. Luxury cars come pre sound deadened from the factory but even they can be improved upon. Good luck out there and thanks for the video.
I just installed Dynamat Xtreme on both my doors.After I did the first one I sat in both seats playing various songs at different volumes.What a difference it made! The speaker just performs so much better with way less effort.Bass is tighter and sound is fuller.The door that wasn't treated sounded so hollow and tinny.Wow,I am glad I did it.It's not fun to do,like open the box up with your new amplifier in it,but it is very rewarding in the end.
Today I decided to try sheet metal over the big hole so I cut the dynamat away and fitted a piece of sheet metal over the hole.Put a thick adhesive foam around the perimeter to really seal it up and placed the dynamat cut out on back side of sheet metal to stiffen and strengthen. End result was no difference in sound at all.Didn't even bother doing the other door.Waste of time and sweat.The bottom line is that just using Dynamat to cover the inner and outer skins is plenty enough to get better performance out of your speakers.People can go nuts with sound deadening and I think a lot of it is ineffective.The only thing that I can see that is truly worth fighting for is getting rid of rattles caused by powerful bass notes.Usually the door card or areas in the trunk.
hey just wanted to say I want to throw this in my truck so bad, and it just so happens that today I CAN DO THAT!! it came as a suprise, and I'm very impatient, but your video gave me so many great tips, in a short time. now I'm confident to start this project, and I truly thank you for that!!! Great job. thank you.
Awesome video. Getting ready to add a new sound system to my Duramax and was thinking about adding Hushmat to the doors, but didn't really know how. The video helps out a ton, and the tennis ball is a genius idea!
+Vic Webley Glad to hear you're adding some sound deadening. You'll never go back once you've had it in a vehicle, it makes a huge difference. Also look into Hushmat's Wave Breakers.
What areas of the vehicle were you thinking of covering? It really depends how much I have to disassemble the vehicle, but I usually charge $50 per door on most vehicles.
You made it look fairly easy I'm gonna try it out myself in my trunk. Good video gave me confidence to do it on my own I was gonna pay a guy $500 bucks to do my trunk and doors.
With great difficulty. It is really designed to be a permanent install. The material is very sticky and if you can manage to peel some of it off, you're stuck with a lot of residue. Plan ahead.
Hey guys, I am looking for more opinions on the placement of the dynamat. I am replacing the backdoor speakers(mids), and the dynamat should make the sound a little better. Some say put it on the door just under the door panel, some say put it on the door skin. In my mind it makes more sense to put it on the door skin. Any opinions?? Thanks..
i want dynamat so bad. i have two kicker cvrs under the backseat of my truck in downfiring boxes and they rattles a lot. only for certain songs though. i ended up taking one out
hey i have a hatchback. how would i put this stuff on there, it has a bunch of small holes not really big enough for my hands or a tool to fit under neath there. would you just recomend having some one like a proffesional doing it?
FYI, generally for every 100lbs of weight you can remove from your car, you essentially get the equivalent acceleration increase equal to an additional 10hp.
On the drag strip it's equivalent to about a tenth of a second every hundred pounds. The questions you have to ask yourself, is your car that low on power you need to think like that? Is it a street car or a race car? And do you like music?
That was not the point. The point was only to provide information via easily quantified figures. What you do with your car is your business but you are also correct, everything in life is a delicate balance of compromises. Similar to the adage: "Cheap, Fast, Reliable; pick two."
definitely looking into this. just did a pioneer overhaul on my factory system, new pioneer double din stereo and all pioneer 3 way speakers only to be disappointed by mushy sounding bass at higher volumes. I mean I get the fact you can't really get deep bass without a sub but I can't even turn the bass up at all past volume 40. sounds good if I keep it in straight treble blasting mode but I'm pretty sure it's just poor acoustics causing the issue, like a concert at a football stadium
+AnthonyJ350 not yet but I think I'm going to do that too, at least for the rear 6x9's. think there is a combination of poor acoustics and lack of power there. front speakers are 4x6 and pretty much are at nominal wattage from the deck and stay clear just have an obvious vibration problem there.
Cory Wilson Ya power is a big factor and what you do with the power. Make sure you also seat your cross overs appropriately so you only play frequencies the speakers were designed to play.
AnthonyJ350 yeah actually on that subject do you know what the -12 and -24 mean on pioneers high pass filter? Noticed every frequency has those 2 options and not sure what that means
Cory Wilson It's how many decibels change per octave. If you slope the head unit and the amplifier it will stack. For example, -12 db and the head unit and -12db at the amp you will end up with -24 db slope.
Great video so thanks for posting. My primary concern has always been with finding someone that knows how to R&R the clip panels etc. Even a certified installer may just slap it in and be done with it unless you're watching the process. Most shops don't allow for this so they may not roll out every nook and granny. I know there are tricks to getting those panels off and on, especially the roof/headliner. Then, of course, there is the seats and carpet. Tough call to find that special someone.
If you're that concerned I would go to the local auto parts store or dealership and purchase extra clips for the installer (because yes they can break). Make your concerns aware to the shop and ask to see pictures of previous work to give you a sense of workmanship. Be prepared to pay a little more because if you're asking for a meticulous job you're adding to shop time. There are only 3 factors in anything and law of economics only lets you have 2 out of the 3, Time, Quality or Money. It sounds like you want a job that requires Time and Money. And yes practically all shops (mine included) do not allow the customer in the back. First for safety and second it puts added pressure to a job where there is a plethora of ways to come to the same result to creativity is on the higher end. You asking to oversee the whole process (when you're technically not the expert) says right off the bat you do not trust the technician and they will question why you want them to do the work in the first place. Hope that helps.
Thanks for the information and tutorial. I thought I had to cover the entire area including the holes so I already ordered that much. I should have enough to do all four doors and the rear hatch now.Also, you kind of sound like Beavis and Butthead's teacher.
How much road noise is reduced covering the inner skin completely vs covering just the metal parts and should I cover some of the outer skin too. My main goal is to cut down on road noise.
+William Ahlers That's a hard question to answer. It depends on how loud your tires are already and vehicle design. You will notice a slight difference by tackling the lower portion of the doors, but if eliminating road noise is your goal you'll also have to do the floor to be really effective.
Im planning to do it in my Accord Sport trunk, but when i popped the trunk lid out all i see is wire. Should i remove the wire and apply to the body or i can just overlay the wires?
AnthonyJ350 so I did the trunk and the shatter really reduced. But the back seat speaker, like the piece of plastic that cover the rear speaker shattered so bad. Is there any way to reduce the shatter?
Looks not too expensive but then you really have to do it on ur own even if it's very long and somewhat a pain in the ass because otherwise paying someone to do it will cost much more than the actual price of the sheets.
Crutchfield_Eectronics also Ebay a number of company's sell from Ebay. Crutchfield gives you $10 off for 4 day shipping instead of two. Also Check other reviews from different sound deadening products that are almost equal to Dynamat as I feel Daynamat has really priced itself out of reach of the average consumer.
Mind to share then? It's pointless to say (USA makes better thing blablabla) if you don't say what it is and where to get it. Is it also cheaper or actualy more expensive than Dynamat, simply because it isn't made in China?
I like ur videos, but have you ever wondered just what exactly this thing is MADE OF? and why it's so expensive? There was another competitor NVX that seems to be the same, and the whole thing looks like aluminium tape, in fact ive seen USEAL in hardware stores which seems like the same shit if not better for way less. There was even a video on youtube of a guy using it to deaden and it was night and day difference vs stock.
I don't know what it's exactly made out of but I have installed it compared to Hushmat, Roadkill and Dynamat Lite and I think overall Dynamat Xtreme does do the best job. Not to say other products on the market won't make a difference, but the Xtreme just really deadens the sheet metal. Hushmat is a great value and installs really easily and Roadkill is pretty thick stuff. Do not use stuff that looks like this from Home Depot, the adhesive used does not stick as well as the stuff designed for an automotive application.
@@InfernoPhilM Might be 1/3 the difference in performance as well. I have noticed a difference between quality brands and cheap stuff. Keep in mind I do this every day
"you could put 100lbs of this." umm.. 100 pounds would make it 100 pounds heavier.. get it? sort of like the question what weighs more? 1 tonne rock or 1 tonne of feathers?
Over priced.. There are other products out there like RAAMmat that are just as good and cheaper. I have competed with both and the only difference I noticed was the price. I always cover the whole door to make it as dead as possible. Just doing small pieces can result in rattles if you run a strong midbass in your door. Might look into Ensolite to stop plastic panel noise.
+Al Complaint You don't have to do the whole area. Even just getting speaker kits and applying only where the speaker mounts to makes a difference. You really need to experience a car with this stuff in. Then you'll know why it's so good. I would rather see someone by cheap speaker, decent amp and put sound deadening in as opposed to buying the most expensive speakers on the show room floor.
