hi everybody what i want to know is there a cheaper sound deadener i'm a broke apprentice and dynamat is so expensive any help would be greatly appreciated
Jaycar Electronics Jaycar sell heaps, and it's much cheaper than Dynamat. The only thing better about Dynamat is their marketing! Bitumen and some tin foil is bitumen and tin foil, there aint much to it!
lol that would be great if Dynamat Xtreme, Second Skin etc. were ashphalt based mate... but they're not. They're butyl based.
If you dont have the $$$ to buy dynamat, either save you pennies untill you have enough for what you need (which wont be much if its going in the ute) or if you REALLY want SD now, then use the Jaycar stuff.....its ok but i'd use 2 layers of it, one dosent really do much im my opinion.
depends what you want really! i used septone body deadener on my pillers, floorpan ( inside and underbody) arches, parcel shelf, inside roof, boot floor, firewall, and when the engine was being swapped i hit the engine bay with it and just used some jaycar mats for the doors and top of boot with and althouhg a pain in the arse job imho well worth doing protects against rust, and [ slightly] improves your sound...
Hmm... well I take that back then! :whistling That said, I used two packs of Dynamat Extreme on my old VT, and I never really felt like I got my moneys worth from it. I got it relatively cheap on eBay, but even so it wasn't all that they make it out to be. I did the inner and outer panels of the doors, plus the boot. If I'd known about the Jaycar stuff I reckon I would have tried that and been a few hundred bucks richer for it! PS. search Jaycar for "sound deadener", they have a bunch of products, I only chose that one because it looked the closest to Dynamat. PPS. one thing Dynamat has going for it is you get free stickers (if that's your thing! )
I wouldn't buy Dynamat either because its so expensive, I imported RaamMat which is another Butyl based sound deadener which performs very well but is cheaper than Dynamat Xtreme. All Butyl sound deadeners are reasonably expensive though as its an expensive product.
I just did my boot lid useing expanding foam... To be perfectly honest, it made a heap of differance... Just a messy job..
That stops vibrations between the boot lid and bracing. Deadening is different, it stops resonances of metal panels.
I used stinger roadkill in my boot its slightly cheaper than dynamat but not by much if I had the choice again I wouldnt of bothered with it as I got better results from filling the boot with spacefoam from bunnings
Hi guys, Sorry to bring up a older thread. I've got a sound deadening question. I've just got my new sub and it's making my boot rattle so much it's not funny. I've got Dynamat in my boot lid but it's still shaking. If I put another layer of deadening ontop of the previous will it be better? I'd go with a cheaper deadening such as the Jaycar one mentioned. Also, my rear windscreen seems to be shaking aswell, is there anything to I can do to reduce the pressure on the windscreen? The sub I'm using is a Hifonic Olympus 2412 (2400rms at 1ohm).
You wanna find out what is actually rattling. Dynamat blocks noise from outside, its not so much for rattles. Often two things in the boot that rattle are 1) the lock mechanism for the boot, 2) the license plate and/or frame.
