battery intrunk

[nightcat]

ive relocated my battery to the trunk a while back but no wthat im in a colder state i think that im having ground issues. Can someone tell me what i need to do to fix the problem. I also have door poppers installed since it started getting cold, they have been acting up. the shop grounded them to the doors but im gonna run the grounds to the body of the car and see if that helps. I have a 0 guage power wire going from a optima battery to the hood and a 0 guage (short) ground wire in the trunk. i was thinking of running an additional ground up to the hood to see if that helps. Also is there a smaller battery that can fit up front to where i can have two batteries in the car.

might be a good idea to use a multimeter and test your grounds to see which ones have the best ground.

Probably will need to extend the wire of your - side of the mutimeter so it can reach all grounding points (using the common + of your battery)
