Ok, thanks for replys. It is a sirius satallite radio
with a receiver connected to the stereo it. The stereo has a 10amp fuse on the back. I gave it a 15 amp fuse in the aux box I connected it to. I gave the little water pump
a 2amp fuse as the manual requested. I gave the 2 aux 12 volt connectors 10amp fuses
. I am thinking because of the demand of the stereo being satellite
I need to boost that main power cable to 10 guage?? From looking at the chart posted 12 is a bit low.
