Dual 0awg wires to a single terminal.

[oeking87 3]

So I've seen this done alot of times and my current build is going to be wired this way because I think it looks badass and I have the equipment to do it but I'm just wondering is there any gain in amps by doubling your wires to your amplifier I have a alpine MRP-M2000 with a single 0awg terminal but wired with customer machined dual 0awg splitters.
