There is no agreed convention for speaker color coding. Most users and most manufacturers will take the striped core as the "+" side and the black or plain as the "-" side. It makes no difference to the connections how the cable is connected but in a system, make sure that all the amplifier terminals are connected to all the speakers with the same polarity. Almost all amplifier and speaker connectors that have red and black terminals will use red as the "+". Therefore, connect the red terminal to the red terminal and the black to the black. It makes no difference which core of the cable is used. If different speaker manufacturers are being used in a single system, it is possible that the wiring may be inverted on one type compared to another. Wiring a speaker with the polarity inverted will never damage the speaker but it does affect the sound quality when used with other speakers. Most of the better speaker manufacturers will state the polarity of the connectors in their manuals. Look for a statement like "A positive voltage on the red terminal will produce a forward movement of the speaker cone". If you are able to confirm this detail for all speakers, getting the polarity right is simple. Although speaker connectors are often referred to as positive and negative, the signal is AC and therefore the terms are not strictly correct. The terms work for the purposes of connecting speakers so there is no need to correct the terminology.
I always use the black stripe as negative signal. Always do this and then when you have to disconnect something you won't get confused.(or as confused) but honestly it's just wire it's up to you.
Any marking (a white stripe, bump molded into the cable, different wire colours) is an indication for your reference only. It doesn't matter, as long as you connect the marked side on the amplifier to the same polarity on the speaker side.
The new speakers come with un-stripped copper wires..... you need a pair of wire strippers.... i put in kenwood speakers and the size of the wire was 14 somethin. you would need to get a wire diagram for you car/truck to see the colors of the positive and negative wires. then look on the aftermarket speaker box to see which wire is negative and which one is positive.... After you would do all this, just match up negative to negative and positive to positive. simple as that. I'd recommend wire nutting the wires or electrical taping them... but DO NOT put all four wires together. that will mess your speakers' sound up completely. wire nut the positives together and then wire nut the negatives together.
It doesn't really matter, as long as you connect them to the same polarity at both ends. Most people use the gold or reddish-copper wire as the positive, as it is the red terminal and the silver, or non-colored lead to the negative as it is black.
It is better to use 16 gauge or 14 gauge speaker wire for your home theater applications.
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
The Speaker wire to use as the negative really doesnt matter when installing new wire as long as all speakers are hooked up the same way. Normally though most people use the solid colored wire as the negative.

According to color code, it is the speaker negative wire.
The left rear speaker wire positive is -Yellow/Blue negative is - Black/Blue The right rear speaker wire positive is - Yellow/Red negative is - Gray/Red
The positive speaker wire is a solid color, your negative wire should have a stripe on it.
