i have a small amp kit in my pathfinder i have now. im upgrading to a big system. i found a good deal on a 0 guage amp kit but it has no rca's in it. is it fine to keep the rca's from the smaller kit and reuse them? or do they need to be upgraded?
also i need to get my alternator rewired to make it bigger is what i was told. what amperage do i need it to be? im hooking up a t30001bd amp. i already have a yellow top battery.
