125 amps. Less if the cable is very long or of poor quality.

Probably in the 120A to 150A range

I have never seen a source that recommended that much. Do you have a source for that claim?

Knukonceptz rates their Kolossus fleks at 150 amps, which is the highest I have ever seen for 4 gauge wire

"Capable of loads up to 150A"

But they include a 120A fuse in there 4awg kit

There are lots of charts available. There is no exact number because what happens is the wire gets hot and it's an arbitrary decision as to how hot is safe. Depends on the insulation a lot as well. Here is a chart that looks generally accurate. I'd probably stay a bit below what they list here since car audio wire is usually very soft insulation. These charts are for copper wire only. If you are using aluminum, they will be just a bit lower.

... just noticed Alvitae's bcae fuses link also has a similar chart if you scroll down.
