Hi mate,

With regards to the picture can i snip where i put.

For the earth on the bolt, is this the Thick or thin brown wire?

Yellow and red you covered + 1 brown. I know you said to tape and forget but whats the yellow&grey, brown&white, plus the brown thats not used for?

Happy with what you say about the speaker wires, whats the red wire for that comes out the metalic blue sheath.

Finally whats the 3rd wire for?

Appreciate all the help mate!
