What's up everyone,

I was wondering how hard it would be to take apart the car doors. I was thinking of buying those sound dampering stuff from circuit city, and putting it all over the doors, not just around the speaker. It seems as if the "armrests" on the door are what rattle.

Also, is there any way to make the car quiter when driving, in other words can I somehow kill all the road noise? Or at least make it quieter in the car (besides not driving it).

Earplugs or noise cancelling headset.

dyna mat the entire car, this will deaden most of the outside noise, keep the air cool, in the summer, and warm , in the winter, inside the car, and make systems sound soo much better, cuz almost everything dont rattle........lol i wanna get it now

Drive at 55mph on the freeway. Then there's less road noise and wind. Also, dynamat your head. That's much quicker than doing the whole car. Cheaper too. It's just hard with the irregular surface (some more than others).

That dynamating my head idea just might work! LOL.

I will probably take off all the plasitc parts, put dynamat around where those parts go, and voila, a quiter car. I hope.

I wouldn't buy the sound deadening from CC. Costs WAY too much. I was planning on buying from them to deaden my xb and it was going to cost like eleventy billion dollars. I bought some b-quiet extreme for about $100something. Look into B-quiet extreme, dynamat extreme, fatmat, etc. Much cheaper and works as well.

The door panels come off with two screws and a pull.

I've been driving without the passenger door panel on cuz i was working over there and it vibrates like mad when the door panel is off...

I was thinking that a fin or some relatively minor change to the side mirrors would probably quiet the noise at speed for less money. Also, realize, the xA is pretty well sound deadened already, especially compared to other econoboxes. When the doors shut, the noise drops dramatically. Nothing like a Lexus, but still darn good for its class.

I agree - just spent the day out with the flu scanning in all of my new Japanese ist brochure & magazine review articles into the PC, and the brochure has a diagram of all the areas that are sound-proofed.

They've put quite a bit in this car - sides, bottom, etc, and it pretty much covers most of the area except the spare tire well.

No wonder this car is so quiet (for an econobox)!

anyways, back to burning a backup copy of my new Ist/xA scans....

....now if they could only come out with the Vitz as the next xA in the USA - this new design even has the Sharp Plasmacluster Ion generator air vents - kills germs....

I believe I read somewhere that sound insulation is sandwiched between layers of metal that make up the body. Anyone heard things along those lines?

BeQuietAndDrive

Know how I got rid of those rattles?

Turn up the stereo

empleh

how much does the extra dynamat weigh? i heard its kinda heavy.

BeQuietAndDrive

Dynamat is quite heavy, which is why I would never use the stuff.

I'm trying to get rid of weight, not add it!

If my car weren't new, I'd probably get rid of all the sound deadening stuff. I'd rather hear the engine, music,etc.

I think in most modern cars, it's a sandwich - metal, sound deadening, metal. But you can also see it being applied to just the outside (usually some sort of black overcoat).

The xA does have felt insulation applied to the engine area and hood underside as well.

It would be interesting to hear how much of a difference more insulation will bring....

Also, it's said that there's a limit to the quietness you can achieve due to glass thickness alone -- that's why more expensive cars put in thicker glass as well as more insulation.

Finally, consider a tire upgrade as well. The stock tires are not the quietest riding tires by far (according to tirerack.com surveys on the Bridgestone RE92 I've got on mine), and you can often achieve a substantial improvement in noise levels this way.

Yeah, I have decided just to deaden the doors in order to get rid of door rattles only. Besides, I am trying to save up to go to the World Cup next year. Every little bit is going to help. I hope I get picked in the drawing!!!! Germany here I come!!!

how much is labor and material cost to sound deadened entire car? Would dealer do it and for how much? thanks...
