T Sportline has been installing audiophile-grade audio systems in Teslas since the original Tesla Roadster days. As seasoned audiophile experts, we understand the value of insulating the body structure to optimize the audio performance in Tesla Model 3. The noise reduction difference has been tested to be between -2.8-3.0 db, which is quite noticeable!
Our bespoke audio design team highly recommends installing the T Sportline pre-cut Dynamat® sound deadening insulation kits when performing any audio upgrade, or even simply to improve the factory audio performance. The guesswork of how much material and what shapes to cut it are eliminated by using the T Sportline pre-cut kits. All the work is done for you, just watch our step-by-step DIY videos and follow along. Peal and stick each individual pre-cut piece according to our video instructions. All insulation pieces are CNC cut to ensure a precise and clean fit every time. The kits are constructed from the exact same Dynamat® Xtreme® material customers have relied on for years, to create a quiet, solid, luxury car ride. Dynamat® insulation will reduce road and engine noise to help isolate the passenger compartment and create a quiet driving experience
During decibel testing, a 4-5 dB noise reduction is typically measured. Tire selection will impact cabin noise in EVs, so results may vary between different tire configurations.
