Quick question I plan on adding any extra battery to the trunk I’m going to be running a single z5 12” sundown at 1ohm on a Orion hccaa 3000.1 or maybe a 4000.1 sundown amp not to set on an amp yet also a 480 rms zapco 4 ch for my door and rear stage speakers I was wondering what I will need to add the extra battery. fuse block and power and ground distribution wise, I also want to use smd products if that helps.
