I think the alternator is beginning to go in my boat. I'm running 2 marine deep cycles to power my amps.
My voltage gauge seems to only be around 12v at idle, and as soon as I throttle up, quickly jumps to the 14v range.
I lost my sub amp last week, and I think its due to my alternator being weak and not supplying my batteries with enough juice.
Looking into a higher output alt and wondering what everyone is running!
