Arrow Any ideas on how to make the doors feel/sound more substantial?

I know this sounds weird....many people on this board are bent on making the car lighter for speed. That being said, any ideas on how to make the doors feel more substantial....i mean you slam them with the windows down and they feel like nothing

anyone had any success with anything?

Mike

Dynamat

I remember closing Necromancers door after he had added "sound deadening material" and I was blown away
at the solidness added when shutting the door.

Sound deaden the doors.

I have three layers of deadener in each of my doors, and they shut like a beamer.
I used non-dynamat stuff, and it worked fine. Use the expensive stuff if you want.
Basically, use some asphalt based (or similar) sound deadener to line both sheets of metal inside the door. These are the other side of what you see from the outside (tough to get to, but worth it) and the metal frame on the inside that the plastic interior is attached to. This will give the door a more solid feel.
I also lined the inside of the plastic door interior with carpet padding.
Do a search for sound deadening on i-club, or check out sounddomain.com. I haven't been there for awhile, but I believe they have an entire section on deadening.
I've got pics, but not at work.

1) learn how to not slam your door!!! every time you slam your door, you hurt your car!! if you hurt your car, you don't respect your car, you don't respect cars i don't like you, i will kick your ass!!


2) take the doors off a BMW 7 series and fit them to the suby!!

Default Concrete?

Maclif: fancy seeing you here. We keep running into each other in all the DynaMat related threads.

Some guy in another thread said to use concrete. I think I'm gonna pass on that one. However, I did the same things as Maclif. I used DynaMat Extreme, 7/16 carpet padding, & cans of expanding spray foam. I specifically used the foam around the edges of the door panel & inside the arm rests of the doors. It hardens into a rigid (so to speak) foam to fill the void but doesn't weigh much. Cautions on the foam: if filling large areas, do it one layer at a time & let the previous one totally dry. I failed to do this & it sagged & started leaking out along the bottom of the door panel.

twitch: good seeing you, indeed.

Mike,
If you're worried about tearing up the doors, it's not difficult at all and in my belief one of the best things you can do to your Subaru.

You mentioned weight and speed, this stuff overall will not add enough weight to make a difference in your speed (note, stay away from concrete )

You have to add plenty of weight before your "butt-dyno" could tell.

Isn't it ~100 pounds makes you ~0.1 seconds slower in the 1/4?

Default carpet padding?

Hey guys, here are a few questions that i haven't found answers to on related threads:

1. What does the carpet padding do? Does it help the speaker acoustics, just deaden road noise, make the door feel heavier, or all of the above?

2. Does the asphalt based deadener smell bad? This stuff is cheaper, do you need a few layers to be able to compete with the Dynamat or Cascade products?

Thanks!

Default dynamat will work

Dynamat is the way to go. It will even deaden rattles and creaks and make your stereo sound better and decrease wind noise. Cost is high though. Any good stereo place will have it or try crutchfield.com

Veloce: DynaMat stops vibration & noise. It also has some heft to it (which makes your door feel more solid when you shut it). The carpet padding muffles or attenuates a great deal of the road noise as well. It also is a gap filler that fills any voids between the door frame & the door skin--this eliminates the hollow sound. It doesn't really weigh that much. All these things will make your stereo sound better by reducing the competing noise. After soundproofing my car, I have found that I rarely have to turn my stock 6-disc changer above level 7 (even when going 80 mph).

Jejunum: you need to remove the door skins first. There is a screw in the handle area (where you pull the door shut). There's another hidden screw in the area where the door latch is. Lift the door control panel up & out of the door & disconnect the electical harness from it. There is a 3rd screw tinside where the door panel control was. Remove it. Remove the door latch trim panel from the area around the door latch; you'll need a flat head screw driver with the end wrapped in masking tape to avoid damaging the door panel. Gently but firmly pull the door panel away from the door frame starting at the bottom. Lift the door panel up & out. Gentely pull the plastic away from the door frame. Clean all surfaces with denatured Alcohol. Apply DynaMat to all solid surfaces. Make sure you don't cover any moving parts.

Default you can search I think someone has pics up, but

I would recommend getting or borrowing a pick set, it makes this stuff much easier.

The front doors have three screws holding pieces in. On is in the armrest "cup" at the bottom, on is by the actual door handle, and the third shows up later.

There will be two small screw covers and the screws visible per side. Make sure you don’t loose stuff (I would recommend getting a magnetic parts dish). Take all that stuff off. The part with the door lock and window switches can be pulled out and unplugged.
Then on the front doors you will see a third screw holding the door down in the middle.

After you get that all taken apart grab the door panel near the bottom, slightly under the plastic and jerk it off. Go all the way around the door and you should get it off. Be careful because you could break the small trim ring around the door handle
(I broke 2, they are $6 each at my dealer ). If you are good with a pick you might be able to take it off when the door is loose.

Yank the plastic sheeting off and pull the black goop off too. Throw that crap away. Put sound deadener where ever you can reach. Make sure it is stuck all the way and there are few to no bubbles. It might be a good idea to plug the door controls in so you can periodically check to see if the window scrapes anything.

The back doors have the same two visible screws, but the third one is at the back end of the door panel on the outside edge. It is one of those “screw out 4-5 turns then pull the plug out” thingies (oh yeah the technical terms now!).

The back door should be even easier to dynamat because it is much more open then the front door. The door panel is easy to grab at the lower right of the panel, it overlaps the door there.

Buy brownbread instead. Cheaper and more effective than dynomat.

I'll obviously need 4x's what you guys do, but check this site out:

http://www.b-quiet.com/

They're product is great...and It's what I'm using to totally cover the entire interior of my burb. It'll be gutted, and this will be what I use. If you have the time, and place, I'd look into spraying some of it. Trunks especially. It works great.

Everyone...

Thanks for all the advice...i kinda assumed that i would need to add some sound deadener like dynamat at some point. I put some good a/d/s separates in the doors and now they rattle noticeably. My girlfriend's cabrio doors shut like bank vaults and thats the direction i want to be going in...

i was thinking of packing peanuts myself....

seriously though i shut my door more softly than closing the door on a china cabinet...butmy g/f...whose cabrio doors shut like bank vaults slams it pretty hard. Then i put some a/d/s separates in the doors and now they really rattle. so dynamat sounds like the way to go....

I used Peel-N-Seal from Lowe's. It has the same properties as Dynamat (fundamentally).
It is an adhesive, asphalt, a couple polymers, and a layer of aluminum. It sticks real well (I used a dynamat roller) and haven't caught a scent of asphalt.
I did use a little Cascade Audio stuff, putting a second layer around the speaker (so between the speaker and metal is two layers). It all seems to deaden real well. I plan on doing the floor and roof later.

I believe coverage area is probably the most important element of deadening, not necessarily material used. The more of the metal that is covered, the better the deadening. I have also read that adding two layers of deadening is 2.5 times more effective than a single layer (i.e. - another layer is going to greatly increase benefits instead of marginally increase them.)

Good luck - it is very worth it.

You may want to look into Raammat as well as Edead...

I don't know what the benefits to each are, but I know that Raammat comes in an Original and a 60mil version...

The Raammat 60 is comprable to Dynamat extreme at a lower cost...

If you're worried about an asphalt smell just tape up the seams with gaffer tape, that should cut it down a bit.

good luck.

I personally use dynamat. It made a HUUUUGE difference in the sound level inside my car, but I'm sure there are better alternatives. Dynamat is just readily available at fry's/best buy/circuit city/EVERY car audio shop in town.
