How nice can a Miata be inside? (hardtop, dynamat, etc)
#23
I am planning on coating as much of the interior panels with this stuff as I can before I reinstall carpet. Will try to get as much coverage on the interior of the doors and trunk as well.

There's loads of info out there on sound deadening, and it can be done for fairly cheap if you don't mind it being a little 'ghetto'. The best way to do dynamat is to only put on as much as you need since it only stops things from vibrating. The real quietness comes from the closed cell foam or mass loaded vinyl, which you want everywhere you can stuff it.
I know it's frowned upon to do things cheaply here, but I've seen people do roof flashing and yoga mats and the results were better then you'd expect.

I think something that would make the hard top more effective is adding some kind of layer between it and the car. I don't feel like the seals that come with it are sufficient enough.

I think for my car the main issue is squeaks/rattles, not the overall noise levels. I'm going to be extra careful when going back in with my new dash to make sure nothing can rattle, then maybe add some dynamat strategically to help the chassis. One of my main annoyances is actually due to the hardtop and my non-HT harddog bar, it loves to rub on the hardtop where the two corners are on the bar. I was thinking a proper foam or something, and then bolt the hardtop on SM style. Not sure on that yet, though.

A huge amount of the noise in my car with the top up is generated by the wind coming underneath the seem on top of the windshield. If I pull the top down really tight by hand while going highway speeds the noise cuts down significantly. I am not sure if beefing up the seals or tightening the soft top latches is the best way to fix this.

For me, the hard top on my NB reduces wind noise, but seems to make the engine noise more intrusive. That may just be that I can now hear the engine more with the reduction in wind noise I run the hard top in winter mostly for better rear visibility with the huge rear window. In summer unless it is raining the top is down so I have great rear visibility, but I hate driving with the soft top up.

Firewall and trans tunnel as far back as your wallet will provide material to cover. I'll be using this: Floor & Tunnel Shield II - Heat & Sound Insulation 050501 | Design Engineering, Inc.
Kinda like what the 949Racing guys did with Crusher, but more:
We have a thread about this actually: https://www.miataturbo.net/diy-turbo...t-cabin-74625/

The hardtop makes a world of difference.
You don't need to add expensive dynamat all over a vehicle. Dynamat only reduces resonant noise in smooth panels. Using it for weight is silly.

This guy used to have a breakdown of who made the best materials (which used to be SecondSkinAudio down here in Tucson) but now he sells his own product and his "less is more" philosophy. It makes sense, and would be 10x cheaper than dynamatting a full interior.
