1400ish watts do I need electrical upgrade

I will be running 2 amp pulling 170 amps at max(fuse rating)

My truck has an heavy duty electrical system but what exactly "heavy duty" means I dont know. I had 2 amps pushing 700 watts(100 amp fuse rating total) with no dimming what so ever. Will I need a new battery(stock is pretty fuggin big), new alternator, big three?

Im sure you will have a little dimming, but I wouldnt worry about it. Big 3 would prolly take care of it.
