I know this is a pretty stupid and noobish question, but what gauge power/ground wires and fuses should I be looking into? as of right now I'm only going to be running 600w @ 4ohm bridged across channels 5 & 6 and 190w@4ohm x 2 across channels 1 & 2, but I may expand in the future and tap the amplifier out. So I'm kinda wanting to ensure I can expand in the future without investing more into power delivery.

id get at least 4awg, but if you u plan on upgrading alot in the future get 1/0awg, so you dont have to change out the wires later, nice amp by the way
