    so i bought a new agm battery for the trunk, its a "power tec" 8a24 same as the deka 8a24 if im not mistaken, and my question is for wiring i just bring a wire from positive and negative on the front battery through the car into the trunk and to the battery. and use 2 inline fueses for each battery, and then a relay? and then ground the battery? that was an option i got on another forum just double checking also, i have dont the big 3 with 0 gauge. can i use either 2 or 4 gauge to run to the second battery? or is there much difference from the 0 to 2/4 gauge

    i was told i could just run a pos to the new batt and ground it in the trunk/hatch. i was also told to run a solenoid between the two batts so that the one with the lower charge wont drain the other.

    to me the second one sounds better.
