Power wire - size needed? I am installing the followng:
2 * Kenwood KAC-X4D amps
What size power cable do I need from the battery, back to the distribution block? I will be running 6AWG from the distribution to amps.
These amps will be used to run the following:
Focal 165CA1 - front doors
Focal 100CA1 - rear hatch
Alpine 6062GD Mids - Sail panel
Thanks,
