ok im gettin my orion 2500d on fri. and everyones tellin me to run 0 awg from my battery to a fused distro block, now my first question is, does it HAVE to be fused? i got 2 laying around and they are non fused so i was wondering if ill be fine using those, and i got 4 awg wire running from my battery to my trunk now, i really dont feel like rewiring all that shyt so whats the worst that can happen if i dont use a fused distro block and dont run 0awg?
