I am thinking that it is time to replace the batteries in the boat with the upgrade stereo.
The stereo has 3 amps which includes an Alpine PDX-M6 (600W), a JL HD600/4 (600w) and a JL XD600/6 (600W) for a total of 1800w RMS. Obviously I don't think I will be running at max draw very much but I am trying to find a nice balance of batteries.
I have 2 batteries with an ACR to combine the batteries when charging.
In the past, I have been using Walmart Everstart start/ deep cycle batteries.
Trying to keep it reasonable. Any thoughts on what I should be looking at.
