Ok looking to pick up a second battery that is hopefully under 70 pounds . 2010 gti 140amp stock alt will be running 0 gauge. a 10" sundown zv2 sub and a elemental designs nine.1 amp. Whats a good second battery for this system to stay away from the diming? The cheaper the better, the lighter the better. must be dry cell. Appreciate any info!! used to run a spv70 with a sundown saz1500 and that did perfect but want alittle bit light battery if possible
