how do u know which is black and which is negative null

One wire side has a marking along the length of insulation. Use this wire for all positive connections to avoid out of phase wiring.

I think your question should be which is red or which is black? Or which one is the positive or negative wire. The Rocketfish speaker wire has writing on one wire. If you use that for the black(negative) from your amp to the speaker, use the clear wire for the red(positive) terminals.

You need to look very close to see the markings. I had to use a pair of reading glasses and good light to see the marks.

Typically black *is* the negative. There is writing on one of the wires to differentiate between each one at each end.

There's white text printed on one wire. So you can just decide that is negative or positive and go with it.

Use the text on the one speaker wire to connect to red on speaker and red on receiver. Then connect the speaker wire without the text to the black on speaker and black on receiver. Just ensure red to red and black to black.

I believe one wire has white text on it and the other does not.

You look at the little tiny markers on one wire and designate whichever side you want. The same for all connections.

The wires are color coded - red and white. One for right and one for left. Just be consistent.

Look closely you’ll see black stripes on one of them.

One side has small black +s along the length of the wire coating.
