I would need a very big cutting board! Got power, ground, battery monitor cable and speaker wire for the 2 subs run today. Damn tight fit pulling P+G+M cable up through the hole all at once! P+G are just shy of 3/4" thick, plus loom, EACH! But we did it. Might have the layout of the batteries and charger figured out and need to figure out how to get a plug out of the starboard lounger for the charger, and a little wire from starboard to port lounger. Then I need to cut, glue, and pray, not necessarily in that order! Here is a picture of the possible amp layout, just don't know if it would be to tight to adjust gain and other controls.
