This is my running topic on the changing state of both of my Mazda's.
I have 10+ years of college behind me, and I have always learned faster when using practical applications of the concepts being discussed instead of just extensive reading. In this case, physically having Don there explaining and showing me, step by step, section by section of the car, how and why and where to apply the SDS system was priceless! As you will see in the many following pictures, this is much more of a system, and the full effects were staggering. I say system because the CLD, CCF, Butyl Rope and MLV all have a purpose and work together to vastly change the vibrations in the metal and interior parts, along with sound transmission both into and out of the car. Don has figured out a number of very nifty tricks for installing, one most importantly is the fact that every inch of CCF and MLV can be pulled right out of the car, which you will see below in the pictures. We started in the rear hatch floor area, then worked our way forward on the floor up through the firewall, lastly working on the doors and vertical surfaces.
I have dampened a handful of cars in the past, heck, I nearly covered every inch of the wifey's old Civic with butyl tiles, many sections with multiple layers, but the performance was not like this. Once we were done, I was grinning like a fool, and opening and closing the door in disbelief as to the difference. The level of silence inside the vehicle is really something, almost cocoon like in nature as your ears take a moment to adjust to the change in noise level. In this rare case, I am not the man behind the curtain, I let Don (former large format pro-photographer) photograph the process, so all these photos are credit of the SDS camera.
As for the audio in the car, disregard that at the moment as it is still a 7 year old fully stock Pioneer system as I have had the Mazda only a few weeks and I am spending much of my non-daddy time on the road or away from somewhere appropriate to install audio. The funny thing is, how much better the stock audio system preforms. We were both taken back for a moment once we had finished up, I joked that I might just leave it stock. (Though I did lay down power, speaker wire, and RCA's under the carpet for the impending install which is another topic). This was a great deal of work, more then I had anticipated, but so worth it. I keep telling Don on the phone the additional benefits I keep finding out, the latest being that my 4 year old son goes to sleep much easier now due to greatly reduced road noise levels.
Again, and huge Thank You to Don for all the time, answers, assistance and effort that went into this install.
