Hey Christian, welcome. This forum is actually pretty cool, lots of good peolple. I only use the foam tape in the cabin because it is cheap and readily available. I would dynomat my whole car but I don't have time. Eventually, when I'm done setting up all my stuff, I might do it. My setup is no competition system (I doubt I can reach 150db) but I am proud of the sound I'm getting right now. Everything I've done so far I've done on my own with no help (my friends think I'm nuts to spend so much on a stereo) Have fun with your stuff man!
