I'm building a 72 VW bug for a daily driver. The previous owner started smoothing the dash and I'm finishing the project. I really want a totally smooth dash with no stereo head unit. I want to run my system off of an Ipod connected to an amp. I know it can be done because some other VW guys are doing it, but I'm confused about a couple of things. First, how does the system power on? Do I just connect the turn-on lead from the amp to a switched power source? Second, what do I do for volume control? I need to wrap my head around these things before I start filling in the radio opening in case I shouldn't do it
