S.E.X. 2.1 C4S Upgrade Kit


Here is an easy to install kit that will give your current version V2.1 S.E.X. kit a more quiet background, better resolution and tighter bass. This kit has been available in the past for previous versions, but we have updated the PC board and the mounting setup to make a cleaner installation.

The newer 3.0 version of the S.E.X. kit has a slightly different kit here.
