what kind of power will a sundown 3500 do at 1ohm on this electrical
160-170 idle 250 max DC power alt, big 3 in 1/0, 4 runs of 1/0 to the back 2 ground 2 power, 2 extra frame grounds in the back to the battery. The front battery in a gold duralast for now, in the back I have a stinger spv70, (70AH) 2 C&D (134AH each) so a total 338AH in the back plus the front battery and alt.
Might sell that spv70 and get another C&D for the back or put the spv70 upfront and take the duralast out. Or sell the spv70 and duralast and get two more C&D's another big one in teh back so 3 total in the back and put a 75AH one upfront thats C&D if needed.
