For sound insulation throughout my ride I used generic insulating sheets
from JC Whitney (http://www.jcwhitney.com/product.jhtml?CATID=5312&BQ=jcw2)
throughout my ride (write-up coming soon).  Good price and the result was
better than expected.  Currently I have the rear deck, under rear seat and
under front passanger area done.  I plan on doing in doors and such as I
find reasons to take the pannles off.  One note of warning, order the small
sheets and not the one large sheet as it is a PITA to use and often is
cracked on delivery.

Let me know if you have further questions.
