Speaker use doesnt need anything particularly big.


IMHO anything with less than 2.5mm^2 CSA is to small.

20W into 4 ohms is over 2A... but it's not just the abilty to carry
the required current. The extra resistance reduces the damping on the
loudspeaker affecting the LF response.



Lets see.

Typical 8 ohm speaker, voice coil R typically 6 ohms.
5 meters of 2 core 1.29mm dia cu wire, tot 10m, 0.0128 ohm/metre, total
R 0.128 ohms.

Cable's R increase as a percentage of total speaker R: 2%.
Ie a non issue.
