I currently have a newer Kenwood stereo that easily plays 7 or 8 hours when we are out on the lake at a swim spot, with the engine off. I have a two average sized marine starter type batteries. They are always being charged by shorepower when the boat is at the well. I usually alternate using one or the other on outings.
I want to add a small amp - something with either 4 or 6 channels with 50w RMS power. It will power Polk 6.5" speakers.
For those who have done something similar, did you notice battery drainage problems ?
As noted, I need 7 or 8 hours play time off a single battery without destroying it. I would rather not give up a bank to dedicate to two deep cycles (by adding a third battery). We only run the water pump, vacuflush and radio when we are out. The fridge stays off unless we are on shore power.
