As of January 2023 this kit is included with the Basic S.E.X. 3.0 kit. Here is an easy to install kit that will give your current version 3.0 S.E.X. kit a more quiet background, better resolution and tighter bass. This kit is available for pre-January 2023 S.E.X. 3.0 kits. If you have the 2.1 version of the S.E.X. kit, we have a slightly different kit here.
