How to Apply Sound Treatment! - SQ Daily Driver Build Part 2

[@robertprice9052]

My wife has a Honda pilot and it had an average sound system, and a lot of road noise. We took it on vacation and I hated the vehicle because of the noise. We had a planned trip to Disney for the next summer so I decided to upgrade the sound system and sound treat the car. I had the car professionally undercoated, and replaced all the speakers with premium speakers and added a powered sub under each of the front seats. My son and I gutted the car one weekend while my wife was out of town. We treated all the floor area, inside the doors and cavities. In the hatch we used neoprene floor mat and rubber mounting glue, we also did this in the spare tire storage, and large body cavities. We also used DEP expanding foam insulation in the tight spots in the body structure. I admit we went full overkill but the results were unbelievable. We let the car sit with the windows open for two or three days. My wife was shocked when she drove the car. A friend tuned one sub to pickup where the door speakers dropped off, and the other to handle the deep lows. I underestimated the value of sound deadening, but it was so worth it. I would do my vehicle, except I drive a soft top Jeep so it probably wouldn’t help so much. Maybe the next car.

I had a long phonecall with the owner of Hushmat and he said you only need 80% coverage. Anything more just adds unnecessary weight. He is a degreed acoustical engineer, and before he started Hushmat he designed noise control packages for OEM carmakers. He said that shops that apply 100% coverage do so because they don’t want the customer to feel they are getting ripped off. Above 80% there is no further benefit. Adding weight to a vehicle has effects on fuel economy, handling, and other factors. He further said it’s critical to seal holes in the firewall - sound sprays through them into the interior like a firehose through any small openings. I have been using this Soundshield on my customer’s cars and it saves installation time - you no longer need to apply a Hushmat or Dynamat type product, and then apply closed-cell foam on top.

60% coverage will give you 95% effectiveness with vibration noise in most average applications.

I deadened my truck doors and cut out a lot of road noise. I went through the trouble to measure the road noise with a calibrated microphone and an app on my smartphone to get a before and after. On smooth roads at low speed it made very little difference. But at interstate speeds on a rough road the difference was substantial.

[@syumassh]

Thanks buddy, subscribed. I did this more for a minor rattle in my car door, ended up doing your “wiggle test on all the exposed wires (which were not many) on a new Mazda. Put foam on any potential contact points and TESA Tape on as much of the plastic clips as possible. My car door is dead silent now. Freaking love it.

Before youtube and this channel my first experience with dynamat went very well. I didn't do a cover all but I did hit those important areas just like Mark explains in this video. Great work my man! I've been watching you for a few years now. I've refined some of my skills with your guidance and wisdom. I do car audio installs as a hobby not as a profession. The leather punch is a great idea. I started using that idea recently. I usually just cut a hole with a knife by making an X then cutting off the pieces.

love your videos. learned a lot. i did the doors in my 2015 vw beetle and was surprised that VW actually had put some in it. wasnt but a few pieces, but they took the time to do it. it made a huge difference with the door panel rattles. i ve been going backwards on my system though. ive had to go back into the door a few times. speaker, the foam rings, sound deading. but when you start off telling yourself that its just going to be an upgrade, thats it. and you whined up with 2 amps, new cabin speakers and a sub. lol you get it. when i get my new, louder stuff for the rear and hatch. i will be better prepared. ty for sharing your knowledge with us.

Last fall I did some sound treatment on my cargo van. The sound deadening material killed half the noise, and stopping the symphony of squeaks and rattles by wrapping all the loose parts was the other half. The van now sounds weirdly solid as I drive around.

Differnece in road noise? I did my doors and back wheel arches once and didn't make that much of an improvement in blocking road noise, slight but hardly worth the effort. Didn't use very thick dampener though which might have made a difference. But i Wonder if youd really need to do the floors too.. thats a lot more work...

[@erhanuzdilli9788]

This does really work for better sound quality. In the early 90's in Australia there was only Dynomat available and in my Mazda 323 4wd turbo made a hell of a difference. Its the only way to dence the sounds that do rattle to become victorious in pure sound.

[@davidhenson7445]

Sound deadening, much like others have said, is crucial and underrated. The benefit of it is two-fold. As he demonstrated in the video, it can eliminate resonance, aka "the clang". This helps minimize sympathetic vibration in the area where the material is applied. This will lower the noise floor in the car, but where it will it have massive impact is in the doors. When applied in the doors, it concentrates the surface area making audible sound to the actual speakers. This will lower noise, lower phase cancellation, allow the front stage to really manifest. Imaging will improve across the board, especially with additional time-alignment. The second thing this sound treatment does is add mass. Mass loading an object lowers its resonant frequency. Why does this matter? Say the untreated metal in your inner doors loves to resonate at different locations between 50-80hz. Throw your speakers in those doors and good lord the buzzing and rattles and shoddy imaging. Add the sound deadening material and the mass of the metal has increased, which lowers the frequency it inherently wants to resonate at. In some cases you can mass load to lower this by 2 octaves or more. Say you got that in those same doors.... now they resonate at 12.5hz to 20hz. Now you can put those same speakers in that door and it will sound pristine with no buzzes.... even full range. This lets you do some creative things tuning the car. Less noise? Lower gains on the amps. Less gain? Less speaker excursion in a given bandwidth. Less excursion? Cross your fronts over lower, getting more of the bass in front of you. Cross your sub over lower and be able to bump the gain in the sub-30hz material without overrunning your mid-bass. This, of course, more of a sound quality setup.

[@csl750]

Good points about covering the whole door and services access points... Was 2 minded, definitely gonna fill those up

[@simonmccoyweightliftingcoa4058]

I am In the process of doing my front doors at the moment (passengers door complete). I had an annoying vibration in my passenger door which I have now fixed and am extremely happy about. Even a little sound treatment goes a long way, as I’m doing it on a budget I was still impressed with the difference. Thanks for the great channel!

[@scherenschnitt6333]

I sound deadened every car I had until now. It is such a big difference in sound. Next step, if it gets warmer these days, will be, that I dampen the wheelhouses where the struts are connected. I think that much road sound is coming through there.

[@dobledekersoulwrekr]

For sure. I used a product called Membrane from Restomod Air on my exterior wheel houses. Made a large difference

[@scherenschnitt6333]

@@dobledekersoulwrekr thanks for the tip. We have similar Produkts here in germany. Your prpduct is in red mine is in blue but dampens too. It even has thesame structure on the alufoil. The distributor is Reckhorn. Which is a little bit to thin I think. It only has 2mm instead of 4 like in the CAF-Video. But I thought it might be easier to apply if I take something like Teroson which can brushed on the sheer metall. Thonking about to being some of it alao under the floor to block roadnoise also. Its a tar like meaterial which cures on air and comes in tins. Because of the material I preferably not use it inside the vehicle. Like the doors. You can easily apply it in thick layers. And also on the not moving components of the steering system. With the last point i am not sure if it will work.

I enjoy watching your videos , I always wanted to get a job doing custom work on cars but in AZ there really isn’t any schools that I know off. I’ve had to trial and error on my own rides. Sometimes in your videos it looks like your doing to much , but like this video compared to others Ive seen where you do the sound deadening and you don’t say if that car is a show car or not, I would presume it’s just a reg car but you do the extreme of sound proof.you state the difference in this video between going all out on a show car as to compared to an all day driver..I wouldn’t close up those bigger holes , maybe in newer cars yes but to everyone doing this to old school cars I wouldn’t recommend doing that.. the reason being is if you don’t care then do what you want to do but for others a lot of old school rides the window mechanism messes up. If you block it with sound proof your gonna have to either rip the whole piece off in attempt to put it back on which it’ll loosen the sticky ness of the adhesive or your going to have to cut a hole where you pull out the motor or the window regulator.. unless you go to the extreme like one of homies videos and make like a separate wood piece or something that gets bolted in and can be taken off at will.. I’ve worked on many older rides and there built more solid then these cheaper plastic cars so these cars have more things to rattle then old schools… other then that advice I think you give good advice on what your doing but some people need to realize it takes time and dedication and just by watching your work and how clean it is they might not get that same end result… I know from my experience trying to mimic some one else and what they where teaching it didn’t come out as clean but over time and doing it over and over I got way better.. I would like to dive deeper in all the wiring within a car , I was told especially with these new cars you have to run some type of firmware mainly when your installing alarms not so much audio but I was told you have to be very careful and know wussup bcuz if not it’s like 1 thing is connected to everything and if you pull or hit the wrong thing on accident the whole car will shut down.. is that true ?? It be interesting if you made a video about that.. anyways good work homie much respect ✊🏽

Lol then there's my Mazda 6 that had a stock Bose system which comes with factory sound dampening. Some of it is actually pretty decent but the doors are covered in a giant piece of ABS. You can get it off mostly and get some material in there but not much on the ABS itself and definitely not much on the internal frame behind it. I only have butyl rubber with aluminum backing on *parts* of the doors right now. Basically the sheet metal that makes up the skin of the door. Throwing in some MLV or CCF is only a dream with hours of headaches right now. On the bright side the ABS shell made it gloriously easy to make custom speaker mounts (all hail the Dremel). The weather striping at the bottom of the windows is ate up (door jam seal is still perfect) maybe replacing that will help the wind noise a bit? Any suggestions on the wheel wells, just multiple coats of rubberized undercoating?

Great video! This is exactly what I'm planning for my old Mercedes. I do have a question though. Since the car gets very hot in the sun, I want to also insulate for heat. From what I found, the SoundSkinz material is only for sound insulation. Would you recommend putting the heat insulation material over the sound insulation? I want my car to more of an insulated cocoon of serenity instead of a rattly old diesel. Currently, I have to turn the radio waaay up to drown out the engine noise.

[@sum1UdontKnOw1]

May not be what you want for a mercades but for about 1/10 the price you could use aluminum roofing rolls. It works about the same as dynomat for sound treatment and should help heat insulation aswell

[@JayeBass]

you need open cell foam with aluminum lining. We offer this through second skin deadener

[@SergioPena20]

Aluminum roofing rolls lose their adhesion in high heat environments. It’s because they have asphalt backing. Sound dampeners have a butyl rubber backing, that’s why they don’t have that problem. They also don’t make the inside of your car smell like tar

[@danrook5757]

Scotty says u don’t have do anything if u have a Toyota Prius

[@imurbrother2128]

Quick question! Do you strictly stick to new cars with warranties? Every car/truck that I've ever bought, I've eventually had to replace either a window motor, window, or opening clips. Issues in the doors happen quite often mainly because they are an impact part (open/close (slamming)) as well as moving parts that more often than not see some kind of exposure to moisture. The abs access panel is a good idea

I have watched a lot of your videos and learned a lot. Where the *#%¥ did you go to school to learn this stuff? You really know what you’re doing. I would ship my car to you for work to be done. You are no joke.

I have a degree in Mechanical Engineering. All the math and design knowledge paid off.

Mark, I am very close to buying your subwoofer design services from your website. I have a question though. If the size of my area will only allow for a port up design, do you do port up boxes, as your website only has side and front firing ports?
