speaker wire color on Vaquero

[ctc6698]

Does anyone know which of the speaker wires on the Vaquero is considered the positive(+) one.

I've got red/white wire with black connector and black wires leading to grey connectors.

By reading the schematics, I'm thinking the red wires/black connectors are the positive but was looking for additional input(s)

Thanks
