After upgrading my Honda Amaze front speakers to Focal components & 4 channel amplifiers , I felt the need for additional sound dampening as on full base the doors used to rattle, considered dynamat which is the ultimate in sound damping however is too costly and wanted a more value for money solution. The icopper mats do the job pretty decently two sheets are enough for the front doors and the glue too is pretty good. The rattles have vanished and the setup sounds a bit richer, that annoying road noise is gone too.
To sum it up, this is a very good solution to the noise problems in today's tinny cars and if you are bothered by the wind and road noise then go for it.
Had Done on My brezza and the performance is great with total isolation of sounds .After installation i have achieved much lower NVH level in the cabin.I had changed all my speaker and now the performance is top notch.Low frequency music sounds so much better without any rattles from the doors. Much need if you are thinking for an upgrade on the car speakers PS:4nos of the sheets are enough for both front and rear doors.
I installed this in my Renault Captur (Installed it myself :) ). This is the best purchase I made this year. The cabin is lot quitter and the music sound more like a premium car audio system that is installed in the high-end cars. Don’t buy the 3M Sound Damping Kit. Its waste of money and there will be no change of any kind.
It is not rocket science to install this. It take some passions and attention to details to do a very professional job. And you will love how calm the car becomes.
If you are planning to buy this and get it installed by a shop. Make sure that you sit with him and make sure that he do’s it right without any spaces between the pads.
