Ok right now i have a red top under the hood and kinetik battery in the trunk.. Ran great for a couple weeks and i noticed my subs werent hitting so i check the voltage on the battery in the trunk and its at 9v which obviously isnt enough. The voltage on the battery under the hood is perfectly fine. So the battery in the trunk isnt being charged right now i have it hooked up via 0 gauge wire from the positive in the front battery to the positive in the back and then i just have my rear battery grounded to the chassis. Is this my problem why its not charging? do i need to hook another 0 gauge wire from the neg on the front battery to the neg on the back? Thx.
