Administrators hughezee Posted September 3, 2014 Administrators Report Share Posted September 3, 2014 Sound deadening, commercial carpet underlay is very good at absorbing road noise Any questions, on further sound deadening or soundproofing please ask.

Founding Member Mazda Man Posted June 12, 2015 Founding Member Report Share Posted June 12, 2015 Hmmm, interesting, I might also have a go at doing this too. Do you just spray that contact glue on to fix it, obviously working around any wiring etc? Link to comment Share on other sites More sharing options...
Administrators hughezee Posted June 12, 2015 Author Administrators Report Share Posted June 12, 2015 Good question buddy no glue used just a snug fit and gravity does the rest 1 Link to comment Share on other sites More sharing options...
Founding Member Cryistic Posted June 12, 2015 Founding Member Report Share Posted June 12, 2015 I've heard of using Flashband as cheap sound deadening to stop panel resonation, anything you have had experience of Stu? 1 Link to comment Share on other sites More sharing options...
Administrators hughezee Posted June 12, 2015 Author Administrators Report Share Posted June 12, 2015 Yes m8y although I've mainly used it for car audio, inside door panels to enhance sound quality, even Geoff's current car has it behind the rear Bose sub sounded allot better worked the same as dynamat at a fraction of the cost The only snag with flashband if used for sound proofing it has to be sealed no gaps in it to deflect sound, so I usually use something to catch/ absorb the sound I don't want e.g thicker carpet ect Link to comment Share on other sites More sharing options...
Founding Member Mazda Man Posted June 14, 2015 Founding Member Report Share Posted June 14, 2015 Sweet, I might have a go at doing this to The Purple One together with perhaps fitting a new mesh grille that AhsyV6 has. 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted December 23, 2017 Moderators Report Share Posted December 23, 2017 Having spent the last few days at high speed , no not me the Coupe and "at" not "on" speed!!! I have come to the conclusion I need some sound deadening in the car... is dynamat the only thing to use or is there a recommended alternative??? 1 Link to comment Share on other sites More sharing options...
Founding Member PaulS Posted December 23, 2017 Founding Member Report Share Posted December 23, 2017 I used Noisekiller in my Mitsubishi but have not compared it to Dynamat 1 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted December 24, 2017 Moderators Report Share Posted December 24, 2017 Thanks for that, is there a recommended supplier or just search the net? I understand that dynamat is really for audiophiles???!!!! I just want to knock off the road noise from the tyres, is it better to tackle the wheel arches first and see if it helps or are there other areas of the car that people have found create the noise? 2 Link to comment Share on other sites More sharing options...

Moderators PTR200S Posted December 24, 2017 Moderators Report Share Posted December 24, 2017 Hmm, that's interesting, i presume there are airgaps then where old sealant has dropped off? Or is it just a volume of stuff to stop the panels resonating? If the latter, then maybe the old style sticky pads for panels we used to use a lot of years ago will help too? 1 Link to comment Share on other sites More sharing options...

There were plenty of cracks in the original factory sealant, so you could seal the whole area and leave one gap and you wouldn't notice much improvement as it all needs covering to get the best results. 1 1 Link to comment Share on other sites More sharing options...
Founding Member PaulS Posted December 24, 2017 Founding Member Report Share Posted December 24, 2017 I guess it is better to search the net for both comparisons and suppliers.... Not sure Dynamat was around when I did the Mitsubishi so I never did any comparisons 1 Link to comment Share on other sites More sharing options...
Moderators Laird_Scooby Posted December 25, 2017 Moderators Report Share Posted December 25, 2017 Dynamat has been around for donkeys years, i remember seeing adverts for it in the back of Custom Car that my elder brother used to buy in the early 70s. I bought a roll of self-adhesive sound proofing some time ago, haven't used it yet but will soon. It was about 5m long and about a metre wide for about £30 delivered. If memory serves one side also had foil on to insulate thermally as well as acoustically. 1 Link to comment Share on other sites More sharing options...
Founding Member AhsyV6 Posted January 5, 2018 Founding Member Report Share Posted January 5, 2018 Hello mate...this is what I used a couple of years ago and was very impressed with how solid and weighty the doors sounded when closing.I would use a deadening material to reduce resonating/vibrating and then a underlay like Stu to sound proof.....they both do different jobs and have different qualities 2 1 Link to comment Share on other sites More sharing options...

Moderators PTR200S Posted January 12, 2018 Moderators Report Share Posted January 12, 2018 Still haven't bought the pads and now they are out of stock ... There will be more coming apparently... Anyway , in an effort to push it on a bit further I though I would drop the back seats and have a look at the rear of the arches etc,,,, every clip holding all the trim on is missing Someone has had it all apart in the past, shocks tops look new, maybe have been replaced so going to have to have a poke around further and see what to do, may just be a case of soundproofing and clipping it all back together properly... here's hoping... 2 Link to comment Share on other sites More sharing options...

Same company too! looks a better deal too ... and I have a sharp pair of scissors, mind you, don't need them really, swmbo can cut anything at ten paces...... They do 3m of this stuff too but its out of stock as well! anyway, ordered 5m got plenty of things I can stick it on!! thanks Dave 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted January 26, 2018 Moderators Report Share Posted January 26, 2018 Ok, all stuff arrived so now to strip the back out of the Coupe. Anyone any views on if its worth doing inside the boot? up the sides for instance? Over the petrol tank top? Obviously I will be doing the wheel arches and under the rear seat when i figure out how to get there ! Link to comment Share on other sites More sharing options...
Moderators Laird_Scooby Posted January 26, 2018 Moderators Report Share Posted January 26, 2018 I'd do the wheel arches in the boot and the inside of the rear wings after removing the trim of course. Also the underneath of the parcel shelf - it's metal and i've known mine to vibrate at times. I'm assuming your boot mat is similar to the Rover ones, grey mat glued onto a piece of hardboard over the spare wheel well? I removed the carpet from the hardboard (wasn't difficult, the glue had more or less dissolved over the years!) and fitted some foam/sponge carpet underlay to the carpet and then the hardboard back on the bottom, this worked wonders for sound insulation! It's also cheaper than using the expensive sound foam to do it! Gives your boot mat a "luxury" feel as well and means the bit over where the fuel tank is gets covered but can be removed as easily as removing the boot mat. As for the rear seat cushion, i'm thinking it's almost certainly the same idea as mine - kneel on the front edge of it facing backwards, put your hands in the gap between the cushion and backrest/squab and pull towards the front/top of windscreen. When the rear end of the cushion is free, lift the front end out of the holes/grommets that the hooks sit in. Worth double-checking with Stu on this one as they may have hidden a bolt or three somewhere to minimise vibration from the rear seat cushion. 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted January 26, 2018 Moderators Report Share Posted January 26, 2018 Good idea on the boot mat, Dave, I have managed to do the drivers side of the boot today, in between jobs .... got some pics which I will post at some time when I finish the job completely. Got to tackle the rear seat and the nearside boot tomorrow if I get a chance......however, tomorrows jobs include trying to get the rear door of a VW Polo open... locks or catch has jammed somehow so may not get on the Coupe..... 1 Link to comment Share on other sites More sharing options...
Moderators Laird_Scooby Posted January 26, 2018 Moderators Report Share Posted January 26, 2018 Little idea i had for doing the floorpan under the seats Pete - use the OE car mats as a template but cut the sound foam about 1/4" smaller all round (thickness of the carpet) then fit it on the actual floorpan under the factory soundproofing. By making the pads smaller the carpet should follow it's original lines while still removing drumming and improving general sound reduction. I haven't tried it yet so if you do it that way i'd love to know if my idea works, my roll of insulation is sat behind the sofa waiting for the warm, sunny day when i can change the carpet over! Then i'll do the sound proofing as well. 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted January 28, 2018 Moderators Report Share Posted January 28, 2018 Managed to do the nearside rear boot today but when I got to the back seat I couldn't get the base out.. Undone a 10mm head bolt at back of squab but cant get it out... Must be missing something somewhere, wondered if I need to take backs out first?

Once the 10mm bolt is loose enough, lift up the front of the rear bench seat/ base directly behind each front seat with a sharpish tug upwards this should free it from the two retaining clips underneath and then it should slide forward lifting it up in the process. 2 Link to comment Share on other sites More sharing options...
