Will my stock alternator be enough?
 

Im going to be installing a Revolution 1500.1 amp soon and I believe the max current draw is 170 amps. So my question is as long as i dont crank it too much I should be ok with my stock alternator right?

I dont intend to run my system with the car off, not now atlease maybe in the future. Im just concered with the car stalling, would this ever happen?

I plan on getting a red top under the hood, and upgrading my bat wires.

Another question I have is, are batcaps worth it?

if i put a red top under the hood and a yellow top in the back, would a 120 amp system hurt the lift of the alt?
