Is my factory alternator enough?

Wondering if my stock 160 amp alt is enough power to run a Fos T1500-1 and Fos T400-4 without issue. No big 3 upgrade done yet and currently running 4 gauge wiring.

160a is fine as long as you upgrade the main battery and do the big 3. I would upgrade the wiring to 0ga with a distribution block to the amps.

Only one way to find out. Stock alts are rated at max and at a high rpm we never see under normal rpm's. They are designed to power all the accessories and then some but not a whole lot. 

If you have enough reserve it will be fine but if you get flickering lights thats a sign that your electrical can't supply enough power for the demand.
