hey im getting on my way 2 putting in my sounds in the next couple off weeks but first im gonna dynamat it i know im deff gonna do the boot but when you buy the boot pack it only gives enough to do the lid the floor and the sides does that mean your not suppose to or better if you dont do the underneath off the parcel shelf and the back of the rear seats? and also i was going to put some on the top off the parcel shelf (on the metal when you remove the parcel tray) so would i be best to jus do the boot just the sides lid and floor considering the places where theres not enough is where my subs will be sitting
Well the centre carpet piece has insulation under it, unlike the rest of the pieces, so, if you skip it, it still has some insulation. The parcel shelf ,( talking about the pressed fibre insert), also has insulation, although its quite thin. If you can afford to, buy an extra boot pack, and apply it to those areas, and you'll end up with some left over pieces. Afterwards just run the sub on it's own, without any speakers, and move around the cabin, and listen for any panels, or interior bits that are still rattling, or resonating, and see if you can use some of the left over Dynamatt to fix them.
Also, Dynamatt can work out to be very expensive, and unless your running a very expensive, and high quality setup, i wouldn't put so much emphasis on the sound deadning, particulary the boot area. I found in my VP, running a single 15'', that the only loose or resonating panels i had, were actually in the cabin. And were pretty easily and cheaply fiixed, once i found them..
yer it will be a mean system which is why im dynamatting haha and not 2 expensive for me reasonably cheap not using it to really stop rattle jus to get better sound but yer thnks anywais
you will get far more benefit from dynamatting the front doors before getting to the boot
and when you do get to our boot i would start with the lid and parcel shelf then maybe the sides and finally the bottom.
really the areas that need it most will be the thinner panels and panels without any rigidity
but do your doors first
i still would like to know and i think ive figured this out myself and prob end up being a stupid question but is it best 2 dynamatt around the areas where the subs will be sitting (in my case up against the back seat) so that would be the back off the seat and would it be better if i did the top off the shelf (inside the cabin) underneath the parcel tray or the underside off the shelf (inside the boot) or both?
I agree with 2LOUD2OLD, do the doors first, both inner and outer skins, for far greater benefit. Also seal the service holes in the doors with mdf. Next do the bootlid with dynamat and if you have any left over do the boot floor. Try and get some carpet underlay for the parcel shelf to stop rattles. You should be able to get away with one bulk pack for all of it. If you are smart in your application of dynamat and other deadening material you'll get much better results as opposed to just slapping it everywhere in the back fo the car.
mate im not so much worried bout the doors im not asking about the doors im asking about the boot in the specific places i asked about.. the doors will be the second thing i do as most off the time your music will overpower the sound off small rattles in the door i just want to kno abouyt the under and top side off the parcel shelf should i do one or the other or both? any1 else who wnts 2 comment but not about what im asking thnks for yur thoughts but dnt bother i jus wnt to get answers 2 my specific question.. thnks
Well i wish i did my doors b4 my boot, door rattles come thru pretty easy and are closer soo you hear them more.
I noticed buggar all difference with my boot done, doors should be done soon ive regretted doin the boot shoudl have done the doors first.
Your sub will be louder than any rattles comin from the boot.
I would work on the inside first, will get alot more noticeable gains
Don't worry about doing the boot floor as you will have no flex on the floor what so ever. So just do the pracel shelf,boot side walls and boot lid. Also try ot double deaden these areas to make sure that there will be no noises what so ever. Also do about 3 layers on the front door inner and outer skin, also try to seal up the holes in the front doors aseell before you put dynamat on the outside skin. use something like carboard and gafa tape will do wonders.
First of all lets get this clear - Dynamat does NOT stop rattles. It lowers the resonant frequency of whatever it is applied to= it stops resonating panels, not panels/interior bits rattling against eachother. If you want to stop rattles specifically in the parcel shelf you need to use some sort of soft material like carpet underlay between the shelf itself and the metal underneath.
But hey you seem hell bent on dynamatting your whole boot so why not go for it, waste $500 on dynamat and cover your boot, hell do it twice just to be sure. Maybe after that you will realise what sweet fa difference it will make.
Listen to the pro's mate, they have been their and done it all before. You wouldn't be getting the same advice from 4 other people, if it wasn't the right thing to do.
And no the music will not overpower the small rattles like you stated, these rattles will only become louder and worse, along with the sound. Don't Dynamatt something just simply because you think it will improve the sound. You must first identify the area's which need attention, and then go from there.
alright so obvioudsly every1 on here would rather do there doors then there boot well good luck to you all thats not the way im going considering thats not the question i was asking about.. and plus you are all talking like ive never had a car with a mean sound system b4 or i have no mates that have good well ive done my own sounds b4 and have many a mate that have to so i kno where shit is gonna rattle and shake the most and it certainly aint the doors and yes the sound does over power the sound off rattles unless its a major extreme rattle like the bootlid or the number plate.. but you kno each to there own still thnks for your feedback to bad it wasnt wat i was looking for but all gud
havnt got it yet let you kno when i do
does any1 kno where to get a dynamat roller? ive looked in supercheap art shops for something similar but cant seem 2 find anything only ones i can find are on ebay in america, all i want is a small rubber roller bout 2" wide any help would be great
Looking at getting a door dynamat kit for my ute. I only run 1 set of splits, but i still seem to get some unwanted vibration. You guys that have dynamated doors in a VS, does it make a lot of difference? Is it worth it? I can get a kit for $40 which is pretty good i think, but if its not worth it then i won't get it.
There is a lot more to using Dynamatt than just buying as much as you can, and putting it everywhere you can.
To get the most out of Dynamatt, you have to understand how it works. It works by lowering the resonating frequency of a panel, acting as a dampener if you wish to look at it that way. Now different panels may resonate more so that others, and also more so at different freqeuncies. However it's mainly low frequencies that cause a panel to resonate.
Seeing as you only have single set of splits, you could improve your sound quite a bit without spending too much money. Ultimately the best way to determine where, and how much Dynamatt to use, it to play test tones, to find out what frequencies are causing the most amount of resonance, and to which panels.At this point you will know which area's need the attention. By applying and then testing, again with test tone's, your able to see if you have indeed made any difference.
Without working on the vehicle myself, my advice would be to begin with the front doors.Identify the crucial area's of the door, then go from there. Also you might want to try adjusting your high pass filter, and maybe look at running it around the 50-60 hz mark. I wouldn't go any higher, because you will begin to lose the full range effect after that, but 50hz would be a good point, which would reduce some of the lower freqeuncies most likely causing the resonance, and will also allow for a little bit more volume and clarity out of your front speakers.
Good luck with it, and Happy Easter
