Had a question in regards to my 2016 Scion Tc and would much appreciate any advice! So long story short I've upgraded my cars headunit, speakers, and added an amp and sub in hopes to combat the terrible door rattle that comes along with having 8 inch subwoofers in the doors. To no avail my car still sounds like its about to fall apart, mainly the doors. And yes I have already wedged a bunch of foam where the window and door lock switches are.
So my question is, what have you guys done to your car to help with all the noise and vibration? Does dynamat even help? Im currently running a Sundown Audio LCS 12 inch sub powered by an avionixx amp, JVC head unit, Focal RCX-130's in the rear and ISS 690 components in the front. Just wanting to enjoy this awesome setup Thanks in advance! Im almost feeling hopeless..these plasic doors are terrible.
