Is the amp 4000wrms or peak?

I'm running 3500wrms + and will be running 300ah of battery and 400a of alternator. Along with f**k loads of 50mm2 power cable

Ideally a split charge relay to charge a second battery in the boot.    Possibly look into uprating your alternator to match the demand too!

summed up perfectly /\

bigger battery
2nd battery
bigger alternator
zero gauge wiring

saying that though, does anyone know what bigger alternator is compatable to a change like this?

for example, on my corsa, i change the 55amp to a 75amp from an astra...
