VW Jetta Mk6 Rockford Fosgate Speaker Upgrade and Sound Deadening 

Upgrade the factory 6-speaker set to Rockford Fosgate R-165-S speakers front and back. This will add tweeters to the rear finally. Also doing sound deadening mats in the door panels. As well as getting rid of the rivets mounting the speakers and installing Riv-nuts to use proper mounting hardware!
