I recently bought 2 POLK MOMO 12" subs and after the successful installation my installer recommended Dynamat "to keep the bass in"

Yes is does what its supposed do a reduce rattle but wont that mean people outside the car wont be able to hear it as well??

Eg. When going down a street no 'boom boom'???

    it does and will enhance midbass. I installed it in all my doors and i can say yes it does the job it is intended to do. I recommend the Xtreme Door Kits, sold on wooferetc.com

    I have to agree with Jstas... why would you want people outside the car to hear your music? From another perspective, if you must annoy everyone around you, you could always roll down the windows.

    But would Dynamat make a significant difference with a stock stereo sytem? Or is the effect more pronounced with decent, aftermarket speakers?

    Keep the dynamat out. If you do, I would have better luck never hearing your booming piece of **** along side me again. After all, you're basically broadcasting that you have some valuable merchandise outside in a fairly unsecure place for all the crooks without 'boom, boom' to steal.

    No offense of course. Just a thought based on security.

    Its a good idea no matter what. A lower noise floor will make any stereo sound more dynamic. Also when your driving without the radio on the car will be quieter. Why not make a Toyota as quiet as its Lexus cousin?

    The thing about sound deadener is not to enhance the sound you want to hear but dampen if not eliminate the sound you don't want to hear.

    By reducing background noise, you reduce the amount of audible interference that is present in listening environment. That interference is known as "white noise". The problem with white noise is that is random in every aspect from pitch, tone and frequency to amplitude and phase. This means that it cancels out parts of the sounds that you do want to hear and it makes for an incomplete listening experience.

    By adding sound deadener, you reduce that external noise to a minimum and give the sound you want to hear a fighting chance. So, given that idea, sound deadener is good for any stereo. Just beware, I have seen people add a couple hundred pounds of deadener only to find out that their gear doesn't sound quite as nice as it used to. A more ideal listening environment can make the drawbacks and short comings of listening equipment seem more apparent than they used to.

    Oh and background noise comes in all shapes and sizes from vibrating body panels to screaming kids to tires rolling down the highway.

    Sound deadener adds mass to an object by bonding as completely as it can to the surface of that object. That bonding changes how that object reacts to the environment around it by filling voids in the surface, bonding to the material as completely as it can and adding extra weight to the object itself through that bonding. It can also add strength. All that stuff changes the resonance of the object the sound deadener is applied to which in turn changes the frequencies that it vibrates at. If it drags that frequency far enough down the spectrum, your stereo may not be capable of reproducing sound in a range that would cause the resonance and vibrations that color sound.

    It handles the other sound problems by either absorbing or reflecting the other sounds away from the listening environment.

    I've used Dynamat Xtreme which is good stuff, but have now switched to Second Skin's Damplifier Pro which seems to be better stuff at a slightly lower price.

    If you're only interested in Dynamat however, there are currently some smokin' deals on the stuff @ Ikesound.com (but call first and make sure what you want is really in stock).

    Will dynamat quiet my screaming kids down? Sign me up...;)

    Sure would be a nice option to get on a new car-factory installed dynamat (or equiv.). To me thats a much better 'option' than heated side mirrors with wipers.

    There are car companies working on that idea. GM is using Quiet Steel and specially laminated glass. Ford has recently come up with their own super sound insulator of some sort as well. Ford has their own glass solution, they call it a SoundScreen windshield that has a layer of vinyl to quell some wind noise.

    Ford has had pretty good sound deadening for a long while. My Thunderbird was like a vault for a car that stickered for around $24K new in 1994. I know they are stepping up the game because the Five Hundred, when new, before it was rebadged the Taurus, got higher sound isolation ratings that every other car company but Lexus and even then they were only a couple points behind with it. Go test drive a new Taurus and see for yourself. That is a very well executed piece of automotive engineering and it can be had for around $22K nicely appointed.

    I agree with this it's STUPID o i need more bass because i cant be heard from three blocks away. There is a big difference from balanced sound. And let me blow my F***ing ear drums out how can you even hear anything else except bass. STUPID PERIOD.

    As a general rule, you can never have too much Dynamat. If I could afford it I would pull everything out of my car and slap about $5000 worth of Dynamat in there. Ive heard a couple of cars that had a couple grand in deadener in it and it makes a HUGE difference.

    Its hard to explain but the music seems "isolated" from you. When youre in a normal car listening to music you feel it with your seat, door panels and arm rests vibrating. When everything has a ton of deadener on it, you dont feel anything - you just hear the music. It no longer seems part of the car but rather a soundstage all by itself.

    My point exactly!! My truck sounds best tuned down to a comfortable listening level. Now mind you its louder than the inlaws want to hear it. But that said the people next to me surely can't be "feeling" the bass as I pull up to the gas pumps. But I know its there. And it sounds good to me.

    Hey fellas.. been a while since I've posted but here's some pics of a recent install of FatMat along with 2 sets of SR6500's in an '08 Suburban. Fronts are seperates and rears are coaxed. They are driven by a Directed Audio D2205 6 Channel amp that is actually surprisingly nice sounding.
    Thought you'd like to see the DynaMat FatMat installed. Made the mistake of trying to cover as much of the door as I could only to find out it was to wide in somes areas and showed after re-installing the door panels. WOW! that was no frickin' fun after letting it set over night. WARNING! This deadner stuff is sticky as H..E..double toothpicks and you WILL fight it to get it off... so measure twice and cut once. If had to do it over again I would take a fairly fine pointed black marker (or similar) and outline the door panel BEFORE removing it leaving a visual reference as to where the FatMat should go.
    Besides a little first "operator error" it was pretty basic, common sense stuff. Notice the pictures showing an 18" x 18" pc BEHIND the speaker mount to absorb a little backwave action.
    Some tips... use both a VERY sharp stiff blade amd scissors, use a hand towel to smooth it out and press it onto the door (save your fingers and keeps the staining of your fingers to a minimum), take pictures of the door and DO NOT rely on memory to figure out the holes the should and shouldn't be covered/opened up/slit. 2 people are better than one... this stuff has about a 5 seconds set time and once pressed on... well good luck trying to get it off!
    These speakers are still not 100% broken in but sound SPECTACULAR. Just love 'em.
