Sealing And Deadening the Doors

I may end up going with a layer of their luxury liner pro over the cabin floor if i really want to quiet things down.

Sounds like a solid plan. I think the luxury liner on the floors is a good application... and will keep the weight on the lowest area. Definitely post up your impressions when you're finished.

Dynamat was one of the bigger names in the business back when I started, but various cottage industries were starting up and offering their sound deadening products as an alternative, companies like Second Skin and RAAM Audio, and they were offering a better product for a better price and their owners were out posting on forums offering their knowledge and experience and answering a lot of newbie questions.

Now these companies are more established, and the lines have blurred a little between them, but they're still good resources and the product might be a little more pricey, but they've managed to carve a niche market.

I do believe in brand loyalty, and when someone makes something that I know works and that I like and can count on 100%, I'll come back to them first, even if it's no longer the cheapest option. I know that I can send an email to Ant, the owner of Second Skin, with a question or problem, and that he'll address it right away. I know if I come back to them, then there's a good chance they'll still be around the next time I need something.

Sorry about the soap box... but that's why I buy what I buy.

While Ant is likely very responsive, his handling of DIYMA and a few other things (Like the number of spam messages I get from him that I can't turn off...) turned me off of his products.

As you said, it's all down to personal preference as long as it's a good butyl product.

SoundDeadenerShowdown has been awesome to me and he's a very active member of the community. Came up with the idea of selling things in square tiles to ease installation as well.

Ant's not a bad fellow. He built himself a small empire, but I just wasn't willing to live in it. He's not the only reason I left those circles, but the change in management wasn't strictly positive either.

Haha. Good to see I'm not the only one annoyed by the 3 identical reminder emails pointing to random ebay sales. Not professional.

Other alternatives: Audio Technix may not have the absolute best product in town, but I know Coleman will be at local shows and active on the forums supporting his products.

Audio Wrap makes a great product with strong metal backing. Installs look clean and flat. Good option if you're in the Colorado area.

I just went though the http://www.sounddeadenershowdown.com/cgi-bin/index.cgi website and wow. I learned a lot. Plus his prices are pretty reasonable.

Don is a really good guy. I messaged him on another forum asking if he had any b-stock tiles that he could part with, I needed one or two to fix the sound deadening on my parents' stainless steel sink. I got a box a few days later with about 20 tiles in it, samples of his other products, and a free roller tool for applying the tiles to uneven surfaces.

I'm planning on using the other 19 tiles on my car. I can't really see anything wrong with them aside from maybe a few dinged corners.

I just tried the Mainstays 1.5" memory foam/foam combo and it did absolutely nothing to deaden noise. I'll be returning it and trying one of the other two once they come back in stock at my store.

Mass Loaded Vinyl will be my next step.

Due to my back injuries, I missed out on much of the politics on DIYMA since I wound up unable to sit in front of the computer for long periods of time. It actually didn't change until I got my first tablet a few years ago. By that time I wasn't really spending a lot of time on forums and especially DIYMA because I was unable to work on my car.

Thankfully we've managed to get my back pain under control so I can do small projects without causing serious harm.

So MLV is not necessary for the doors? will a CLD (like damplifier) compounded with a CCD (overkill) be sufficient?

I want to save my MLV (for weight and cost) to dampen the sound of the exhaust by using it in my trunk floor and quarter panels.

MLV will definitely improve your results if your goal is to remove outside sound from passing through the doors.

Using the CLD and CCD definitely reduces the amount of sound that is transmitted through the doors and makes a noticeable improvement as well as cleaning up the door speakers and giving them a more definitive punch, but you will still have some road noise coming through.

My plans are actually similar to yours... I'm planning to use the MLV that I have on the floor to help with the exhaust noise when I finally can afford to upgrade it.

I see.

Yeah the road noise can be annoying on freeway but locally the exhaust not really disturbs the music imo unless it blast it up to 30+ volume. Hopefully deadening just the quarter panels, rear seats and trunk will reduce noise well enough.

I'm planning on picking up an Invidia N1 catback in the coming week, so I'll definitely be looking to see what I can do to relieve the drone that some of the people are complaining about. The Invidia weighs 9lbs less than the stock exhaust, which should offset the weight of using the MLV and other materials.

This actually might be a good reason to pick up some Second Skin Spectrum liquid sound deadener to see how that works. Cure time might be an issue so I'll do a bit of reading up on that.

I will likely start a separate thread on quieting the exhaust, but I'll try to document the process and take lots of pictures. I might actually try to find an app for my smart phone to measure sound levels if I can find something that works well.

[l0aded]

Wow just realized how poorly I typed that lol.. I think I was trying to say that when driving locally the exhaust note disturbs the music significantly unless I blast it up to 30 volume.

Where should I do this the most just to reduce rattle? I'm fine with road noise/exhaust sound, but I just don't want anything to rattle when I get my OEM Audio Plus system.

On this car, a little bit of everywhere!

The trunk, parcel shelf, doors, rear quarter panels are pretty bad. The front doors actually aren't that bad, the firewall and floor seem ok to me.

Any larger panel will vibrate with a sub, and all the wire's and connectors that aren't wrapped in foam will drive you crazy. Pad as much as you can.
