I am wiring in a new marine stereo, Sony CDX-M10 (boat did not previously have one) to an '87 32-2. I have a couple of questions:
1. The primary power wire will obviously go the the switch on the DC panel. The secondary power (for the stereo memory) needs to have constant power. Where is the best place to connect this lead? Direct to a battery + terminal or to where the battery + comes into the DC panel?
2. The ground wire from the stereo is only about 12" long and will need to be extended. Where is the primary ground in the boat -or- where is the best location to groud; on the AC or DC panel some where?
Thanks in advance for the help.
