2016 mazda 6 full vehicle SQ build

Every now and then Jeffrey has time between his full time job and installing car audio in customer's vehicles to work on his own masterpiece. His 2016 Mazda 6 Sound Quality build has the full Second Skin treatment from head to toe. Jeff ordered the Full Size Sedan Build Package with 80 sqft of Damplifier Pro (CLD) and 54 sqft of Luxury Liner Pro (MLV). Then added 36 sqft of OverKill Pro, 16 sqft of Mega Zorbe, 36 sqft of OverKill, and the Premium Hood Kit. Straight from Jeff...

"Second Skin has always taken care of me on all of my automotive sound deadening needs. This is yet another example. I was concerned with my paint longevity from heat and I had concerns about engine noise when I was doing some more spirited driving. Eric recommended that I use some Damplifier Pro and his new product Mega block to tackle this project. The Mega Nlock product was super easy to use. It cuts like a dream with a fresh razor blade and the adhesive is seriously impressive. Be careful, it sticks to fingers really well also.

The results were exactly what I was looking for. My engine noise was reduced and my hood temperature dropped dramatically regardless if it was just sitting in the sun or after my drive home. As always. Great products and customer service Second Skin."

2016 Mazda 6 Soundproofing

2016 Mazda 6 Personal Vehicle Build by Team Second Skin member Jeffrey Hald

2016 Mazda 6 Soundproofing

Mazda 6 Hood before getting the Second Skin treatment. Jeff used Tesa Tape to mark off the areas and create templates to cut material correctly.

Mazda 6 Hood Kit Thermal Insulation

Prepping makes for an easy install. Jeffrey has the Damplifier Pro cut to fit inside of the hood's recesses and the Mega Block cut to fit perfectly under the factory liner. A+ prep work.

The pre-cut pieces of Damplifier Pro fit like a glove. Super easy install.

Next up is the thermal layer, Mega Block has a 1,000 degree F heat shield on it to reflect heat away and thermally insulate the hood. The 1/2' Melamine foam under the heat shield is absorbs a huge percentage of mid-to-high frequency sound waves. Finally, the high temperature PSA backing on the Mega Block will hold strong through the years. It works best when applied to a clean metal surface, pushed on nice and hard with our wooden roller for a strong bond, and lined on the edges with our high temperature foil tape. Everything you need is included in the Premium Hood Kit.

Factory hood liner placed back on over top of the work and no one is the wiser of the premium insulation hiding underneath. Well... Jeffrey knows...

2016 Mazda 6 Soundproofing

Along with Damplifier on the inner skin of the door, Jeffrey likes to use our OverKill closed cell foam to tighten up his door panel gap areas along the edges. OverKill works great at decoupling hard surfaces like your door panels.

Closed Cell Foam Speaker Rings Mazda 6 Doors

Jeffrey has done some testing and found that using our OverKill CCF as Speaker Rings will outperform the other stiffer Speaker Ring options that you can buy pre-cut. Jeffrey knows his stuff, as he tests materials repeatedly until he gets the acoustical results he is looking for in his builds. Beautiful work sir.

2016 Mazda 6 Soundproofing Door

Before placing new door speakers in, slap in a Speaker Tweaker anechoic pad to redirect those noise canceling back waves. Speaker Tweakers will ensure that you don't lose 25% of your music to back wave cancellation. Super easy DIY upgrade.

2016 Mazda 6 Soundproofing

With SQ and SPL builds, the roof is a #1 spot to strengthen up. You have to stop the flex. Damplifier Pro is the solution you need to rescue you and improve that sound quality.

2016 Mazda 6 Soundproofing

Damplifier Pro added to the floor of the Mazda 6 to stop heat transfer and absorb those vibration waves. Nice work! You can also see Jeffrey start to place OverKill Pro strategically throughout his car to decouple surfaces and stop annoying panel vibrations.

Decoupling Surfaces Mazda 6 Soundproofing

The devil is in the details. Jeffrey uses OverKill and OverKill Pro closed cell foam as well as anyone we know. Strategic placement throughout your build will decouple panels and pieces that rattle. If you have an eye (and an ear) for finding the trouble spots, you can stop them all in their tracks.

2016 Mazda 6 Soundproofing

When making an SQ vehicle you need to use a variety products strategically to get the best acoustical response, 3/8" OverKill Pro closed cell foam is Jeffrey's go-to material for panels.

2016 Mazda 6 Trunk Soundproofing

With any sound system, you can't cut corners in the truck. It's absolutely key to strengthen the metal surfaces to fight the flex of the sound pressure waves.

2016 Mazda 6 Soundproofing

Prioritize good Damplifier Pro coverage for the trunk lid as well. The trunk lid is also a good place for some strategic closed cell foam use to keep the wires from flapping against the metal.

2016 Mazda 6 Soundproofing

Last, but certainly not least... treat those license plates! Nothing ruins the sound of an awesome system faster than the back plate slapping against the car. Stick some Damplifier Pro and OverKill Pro on the back and BOOM, no more "aluminum can in bag" sound banging back there.

2016 Mazda 6 Soundproofing

You already know how Jeffrey rolls into the car shows, with that super soft Second Skin t-shirt...Second Skin For Life!!!
