asahitoro - sorbothane is a tricky material to use. One might think more is better, but my own experience leads me to believe less provides greater benefit.
I use it throughout my system between the feet and the components.
As an example - My turntable was sounding great with 1/10" sorbothane on the feet, so I thought I'd try two pieces of 1/8". The result was terrible - the dynamics dropped off and the bass became bloated.
I'd opt for 1/10" sorbothane in your case and even then - I'd put a small 2x2 inch piece at the corners and one piece in the middle
I also spoke to an HVAC installer that uses it to curb vibrations and he said using strategically placed smaller pieces is often more effective.
