how can i tell which of the two splits is the red (positive) one or black (negative) one??
Both wires are the same bronze color. One wire has letters on it the other one doesn't.

I can't trace it back because the wires are under a carpet, but I remember my dad used to follow the "standard" procedure of selecting which wire was which.. I know that the markings on one wire "usually" represent one color (red or black or pos and neg) and that is what I need to find out.

As long as you connect both ends the same, it doesn't matter which is positive and which is negative. All wires have something different on one of the two. Some have ridges, some have lettering, some are embossed. As long as you use the same on both sides, you are good.
ex: lettered side on the positive on the speaker and the lettered side on positive on the source, non-lettered side on the negative on the speaker and the non-lettered side on negative on the source.
Even if you don't get it right, you will only get a slight degradation of sound quality. For years, nobody used polarity and it mattered little.

Is like William Donovan said: But, although, we assume for practical reasons no polarity in AC the true is that, underneath the blanket, it exists too but it switches between the two poles several times per second (usually 50 or 60 times). In practical terms the two poles function indistinctly. I’m mentioning this because this change, each 20 milliseconds (for 50Hz), “creates” a phase. And if we talk about stereo, not matching the phases of two sources, rise phasing concerns. Not matching the phases of the two audio signals can create cancellation or addition issues and degrade audio quality. So, if it is a mono amplifier go ahead with little concern about polarity or phase. If it is a stereo pay more attention to cable colors.

Red And Black Speaker Wire

use a AA battery.
disconnect the wires from your stereo and touch them to each terminal of the battery. watch the speaker cone move in and out as you touch the wires to the battery. try it both ways, until you see the speaker (woofer) move forward as the wires are touched to the battery. when this happens, the side of the speaker wire which is touching the + terminal of the battery is the positive wire for that speaker. do the same for all speakers and you'll be sure to get it right.

Just look back at the source, I'm gonna say he used the wire with the letters as the negative. Positive no letters.

Trace it back to the other end to see if the wire with letters is hooked up to the + or -. If the wires go straight into the amp (no rear connections) you will have to find the manual to see which convention they used.
I always choose the indicated wire (in this case the one with letters) to be the hot (red or +) wire.
