Amp to cab, coated or uncoated cable?????

You mean 'unshielded' I think. Yes, that is correct.

 

I think you mean "shielded cable" (cable apantallado).

Bass -> shielded cable -> GH 1001RB2 -> un-shielded cable -> HARTKE 4X1

 

Not sure what you call it in S America, but *speaker cable* is what you want, and yes, it can damage your gear using instrument cable.

 

It is possible, because normal shielded cable has very small wires, which can get hot and short out if you use them that way. They are only for low-level signals, NOT for amplifier-speaker connections.

 

Duplicate thread.

 

Using proper speaker cable between amp & cab is being ample covered in your other thread.

For the compressor, use shielded cable or instrument cable. Make sure you don't use the compressor in the line between the amp & cab.

 

Yep.
