[forbiddensmoke]

saang material ba gawa yung tape na dinidikit pag nagdedeadening? saan talaga sya ginagamit? napansin ko po kasi, parang ganyan yung pang-tapal sa roof.

[mcbry]

* Please note that you can use any other deadening material just as RAAMmat BXT is used here.

* The use of Ensolite Foam is an additive to the deadening and while it's not crucial, it does add a lot. [/b]

If youre new to automotive sound deadening, heres an easy way to get the big picture. Three questions that may have brought you here:

* How can I make my car quiet and more pleasant to drive?
* How can I improve the quality of my vehicles sound system?
* How can I make my existing sound system louder?

The answer to all three questions is the same: Sound deadening. Simply put, most vehicles are noisy and have lousy acoustics. Road, traffic, engine and wind noise enter the passenger compartment. Maybe you turn the music up to cover the noise, but the sound waves bounce around inside, cause the sheet metal and plastic trim to resonate, buzz and rattle. You might end up with lots of decibels, but most of it isn't what you want to hear.

Using RAAMmat and Ensolite damps vibrations, blocks the transmission of noise and absorbs those randomly bouncing sound waves. By eliminating the sound you dont want, the sound you do want - or just peace and quiet when you want that - is clearer and less distorted. Since you have reduced the noise with which your sound system has to compete, you will hear more at lower volumes. Sound deadening also reduces the amount of energy lost to vibrations and flex in vehicle panels. This all adds up to less noise, better sound at every volume level and more volume for the power you send to your speakers. All of this is achieved by applying RAAMmat to your vehicles sheet metal and trim and then attaching a layer or two of Ensolite foam to the RAAMmat. Simple as that.

Here is what we recommend for a great general sound deadening solution for all vehicles - developed from years of experience and a lot of customer feedback. This is the sweet for results, cost and effort.

Some of us take this further, but going beyond what we describe here will require more materials and time and a willingness to modify the vehicle in ways that just arent for the faint of heart - all for a relatively small marginal improvement. We will have a guide for competitors in the near future.

[size=18]DOORS[/size]

Most car doors are VERY transparent to noise, there just isnt much there to stop it. If you have speakers mounted in your doors then you will also want to make the doors into better enclosures to boost mid-bass response. Finally, the back wave from door mounted speakers pounds on the outer door skin, playing havoc with sound quality.

DOORS WITH SPEAKERS

Remove the inside door trim panel. Most vehicles have a thin plastic sheet that serves as a moisture barrier.




Remove the moisture barrier. If you are going to seal your door with RAAMmat - which we recommend - you can toss the barrier in the trash.




Working through the doors access holes, place a layer of mat on outer door skin, overlapping the seams. This can be slow going. You will have to cut the RAAMmat into small enough pieces to fit through the holes. One layer may be enough, but use the rap test to be sure.

When you are satisfied that the exterior skin is well deadened, build up the area directly behind the speaker with two additional smaller layers, about 12" sq.




For the best results, cover the entire surface of the exterior skin with Ensolite. At the very least, put a 12x12 square behind the speaker.

A NOTE ON RATTLES

Our next step will be to seal the interior facing surface of the door. Regaining access to the doors interior components will be more difficult than it was before. You will have to cut the mat and remove the sheet metal we will be installing to close up the access holes.

The point is, you dont want to do this more times than you need to. This is the time to be sure there are no loose parts or wires that can move around and rattle inside the door. NOW is the time to check for these and secure them with foam tape, tie wraps, etc.

SEALING THE ACCESS HOLES

Sound deadening mat is not rigid enough for you to just stick a big piece over the large openings in the door. You need to build a foundation first. Most any sheet metal that is flexible enough to bend and cut to shape and will not rust will work. Galvanized tin, anodized aluminum, perforated aluminum or even the aluminum roof flashing sold by the roll at home improvement centers will work. Even aluminum screen door repair panels from your local hardware store work just fine. We prefer perforated aluminum because it is low in weight and easy to form but it can be a bit hard to find locally. We use self tapping sheet metal screws to secure it. If you dont want to drill holes, you can hold it in place with silicone sealer or a similar adhesive. Dont use something like epoxy, because you or somebody else will want or need to get into the door at some point.

* You can use hard/corrugated foam instead of the perforated aluminum and secure it using duct tape instead of tapping screws




It is almost impossible to completely seal vehicle doors. Most have wires and lock rods that run from the inside to the outside surface. Slip some wire loom or plastic tubing over the lock rods to be sure they will still move freely. TEST everything before you lay RAAMmat over the surface. Cover the entire interior facing door skin with a layer of RAAMmat, overlapping the seams by about ½ inch. Use the rap test to see if some areas need additional layers.

Remember to leave an inch from the edge of the door panel untreated to allow for proper fitment. Leave another inch around the panel clip mounting points.

FINISH UP

Add a layer of Ensolite on top of the mat.




TRIM PANEL

Tap on the door trim panel and apply RAAMmat to the back side of any resonating areas. Usually, about 1/4 to 1/3 of the surface is enough. You can also apply a layer or two of Ensolite. Re-install the trim panel and test the door; slam it a few times and listen for rattles, etc. What used to sound like tin will now give you a satisfying thud.

DOORS WITHOUT SPEAKERS

The choice is yours. Applying RAAMmat and Ensolite to the interior facing skin will eliminate resonances caused by your sound system. If you want to really kill noise and get that nice thud all the way around, treat doors without speakers the same way you do doors with speakers.

[size=18]KICKPANELS[/size]

Remove the kick panel trim and look for hole under the pad there, usually opens up to the lower A pillars. This is a great place for road noise to enter the vehicle. Seal them up with some mat and a layer of foam, you can even add more foam to the back of the trim panel if you wish.

[size=18]REAR SIDE PANELS/OUTER METAL SKIN[/size]

One layer of mat over the area then a layer of foam to absorb ambient noise. Notice, not all areas are fully covered, great results will still be achieved by matting the less supported center areas of each location.

Same as rear doors without speakers.




If your trunk lid is bare just like this:



Adding OEM-like carpeting on top of the RAAMmat would be a great touch of class:
