I am in the process of installing a marine stereo into my boat. I am
thinking of connecting it to the Accessory switch. Two basic
questions:

1) If I connect the unit to the fuse block, do I also need to connect
the battery lead and ground lead to the 12V battery? Or is the fuse
block connection all I need to power the unit?

2) the back of the unit already has a 10A fuse. Does it mean I don't
have to add a fuse to the fuse block?
