Hey everyone, I'm new here and really enjoy browsing through the site, alot of great information. I recently upgraded my sound system in my 2003 Silverado Ext Cab by adding a set of Focal Access 165A1 components and a Boston Acoustics GTA-802 amp to power them. My question is about sound deadening; what would be the best choices for my application? I was thinking inner and outer skin on the front doors, possibly the ext cab hatch doors as well, and also the back wall. From what I've read here I should be doing a CLD followed by something like Ensolite or Luxury Liner correct? Should I add Ensolite or LL to the door skins also or maybe just the back wall? Sorry for the long post I'm new to all this stuff, thanks!
