Good choice on the sound deadener. So nice to see someone building a hot rod who isn't using "peal and seal" from Home Depot or that worthless shiny padded crap I see a lot of non-audio guys using who *think* it is sound deadener. Always cracks me up to see guys spend 100's of hours and 10's of thousands of dollars only to skimp on the stereo and the wiring. Glad you aren't doing that.
