Gauge wire to run a 3200 watt amp

[Chris0879]

I am running a 3200 watt peak 1100 rms 1 channel amp what gauge wire should I use and what amp fuse ? I would appreciate the help ,Chris

There's a lot of aspects that go into it.

Fuse size is usually dictated by amp manufacturer. (efficiencies will be different between amplifiers even if they have same rated RMS power)
Wire gauge will be dictated by length, construction, sheathing, etc.

So not knowing really any specifics you'll have to give more headroom to be safe.
1100WRMS @ 80% efficiency gives a max draw of 98A (Also this 1000W RMS amp suggests 100A fuse so we're not that far off https://www.ctsounds.com/products/ct-1000-1d)
4 Ga OFC wire from Knuconcepts @ 20ft say max draw of 150A. https://www.knukonceptz.com/shop-info/size-guide/
 

So making some guesses, you could get away with 4 Ga OFC wire, and a 100A fuse (maybe 120A) for like 20ft or so of wire. if you do CCA then probably need to go to 1/0.

But those are all just educated guesses
