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.

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...

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Miata getting Damplifier Pro and Luxury Liner Pro on the cabin floor.

Reinforcing the door panel with Damplifier Pro. Follow up with OverKill Closed Cell Foam.

Next up, both the inner and outer skins covered with Damplifier Pro.

Check out that outer skin coverage out past the window. Nice work.

Finish off with the inner door skin treated with Second Skin Damplifier Pro.
