Sound Deadener Question

[675R 10+ year member]

Would it be more beneficial to put a MLV over existing dynamated areas, or to dynamat certain areas in the trunk

I have no subs, nor an amp, just want a quieter ride.

Thanks

what areas are you speaking of that are already dynamated? and what type of car?

MLV is a sound barrier, but needs to be decoupled from the surface. Thats the point of the CCF. If you really just want a quieter ride then follow the 25% guideline with CLD tiles and then fully treat the car with MLV/CCF. Email Don at sounddeadenershowdown.com, hes a great guy and will help you figure out exactly what you need. His emails at his website above

yep, if you want to increase transmission loss -decoupled MLV is the key. CCF is one product, but you can use any similar product that is not fully compressible. you could even use carpet padding. just something soft so the MLV is not in contact with metal. note that for a sound barrier to be effective - it needs to be continuous and air tight. i.e. design the MLV installation as if you wanted it to hold water. any holes or uncovered areas will become flanking paths for noise.

Thanks guys, but I decided with my limited funds, I'm going to invest in a car alarm.

Has anybody done it by themselves? I'm looking at a viper 2 way, non remote start. Is it something I could do, or should i just shell out 3x more at Bestbuy?

Yes, car alarms are fairly easy once you have a shop manual and vehicle schematics. The devil is in the details. Most alarm installs are half-assed and easily bypassed. Installing a security system is difficult and something Best Buy may not do well. IMO the standard alarm install is nothing more than keyless entry.

My security system is not easily bypassed, you won't find the brain and you can't see any connections. You can't even see the siren. I did it myself over a weekend and disassembled most of my interior to do it stealth.

MLV is by far the best investment to lower road noise, and you want it in-cabin. Prepare to remove your seats, center console, carpet to install Secondskin Luxury Liner or LL Pro. I did 2 layers of regular LL in my previous car, a 99 Camaro Z28, and it ended up with road noise comparable to any luxury car except for the ridiculously loud noise from the crappy frameless windows. And that was with the LL installed upside down (mass layer down) - though I had 2 layers, so the foam from the first layer did at least decouple the second layer. (Hey, it was my first time working with MLV - cut me some slack! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif)

I already talked to Don, and will definitely hit him up after I first make sure nobody breaks into my car and steals all my equipment that I needed sound deadener for haha.

Anybody know if it's cheaper to buy it on Amazon, then take it to a shop for install, or just go to a car installation and buy it retail (installation included).

If so, what places are good. I know BestBuy *****, what about Cartoys or something?
