While I don't plan needing (or wanting ) to listen to music in my newly rebuilt Daimler SP250 (with the purr of its newly rebuilt engine) I thought I would plan for the future and run wires in case I decide I want to in the future.... Only thing I'm concerned about is that I elected to keep the Dynamo/generator in lieu of opting for an alternator as I like originality. Any thoughts or experience in the max power I can use (or how to,figure it).
