Ok I was out of town for a few days but I'm on it again right now I'm running it off a 6v battery, I'm not using the 0Z4 but the diodes you suggested, The filter caps are both 22mf @350v. I couldn't sometimes get the vibrator going so I have been using the Solid State Vibrator ( I figure once this is in the dash he won't be able to smack it to get it going). I've noticed it hums regardless which vibrator I use just the pitch is a little different. Grounding doesn't seem to make a difference. Shrunk the 4' speaker down 4 " not easy, tried a variety of PM speakers but all pretty much the same.
