¿Qué grosor debe tener mi cable de altavoz?
Enter the cable length and your speaker's impedance and see which thickness is enough, with the cables in that thickness and their lowest price.
Elige al menos 0,75 mm²
Para 8 metros de cable hasta altavoces de 8 Ω necesitas al menos 0,70 mm² para quedarte por debajo del 5 % de pérdida.
Contamos con cobre. El cable CCA (aluminio recubierto de cobre) tiene más resistencia: elige una sección más gruesa.

Cómo calculamos
The resistance of a cable is R = ρ × 2L ÷ A. Here ρ is the resistivity of copper (0.0175 Ω·mm²/m), L the length of the cable in metres and A the cross-section in mm². The 2 is there because a speaker cable has two conductors: out and back.
We keep the cable's resistance at no more than 5% of the speaker's impedance. That is a common rule of thumb, not a standard. Then we round up to the next standard size.
CCA cable (copper-clad aluminium) resists more than copper. Choose one size thicker. We read the thickness of the cables in the list from the product name. A cable with no thickness in its name is not shown.
