[QUOTE="Truthunter, post: 8529754, member: 592787"] Back in the late 90s when I first started messing around with car audio, I installed dynamat and dynaliner max in my front doors and I couldn't believe how much more bass I got from my Alpine head unit powered Boston Acoustic Pro 6.4 woofers... Some of my friends thought I had a sub in the car. I attribute it mostly to the dynaliner max which had a layer of lead in it, which is similar to todays dynapad, without the lead layer, from the same company, basically MLV/CCF all in one sound blocker. A lot of things have changed since then and there are many companies who make "deadeners" now but I found some good reading on this website: [URL="https://www.sounddeadenershowdown.com/"]https://www.sounddeadenershowdown.com/[/URL] Thread on DIYMA comparing "CLD" or Constrained Layer Dampeners: [URL="http://www.diymobileaudio.com/forum/member-reviews-product-comparisons/146403-sound-deadening-cld-testing.html"]Sound Deadening (CLD) Testing - Car Audio | DiyMobileAudio.com | Car Stereo Forum[/URL] [/QUOTE]
