the only soldering I've done is when I replaced the factory speaker wire with 16ga wire, I cut some old aftermarket speaker harnesses in half and soldered them to the +/- speaker wire. That was fine for speaker wire but what I'm gathering from this discussion is that soldering power wire probably wouldn't be in my best interest.
My plan now is to get a distribution block, but am I supposed to split the current 8ga power input into 8ga power outputs, or am I required to rewire the car with 4ga wire and then split that? I'll rewire the car if necessary (always easier the second time around) because I want to do it right but I am making sure if it is indeed what I have to do.
