Electrical Upgrade Needed?

I apologize in advance for my ignorance, but am looking for suggestions:

I have an upgraded stereo (double din ina-900 alpine screen headunit, focal fx45 components, alpine type s coax in back, and an idq10 sub. Amps are interfire mono and alpine 4channel. Not 100% sure of the exact outputs. To take an educated guess if I remember correct, interfire is 800w peak and alpine is 400w)

Lights: I am running a 50" bar on the roof, 32" on the bumper valence, 2 pods forward and 2 rear.

Am I'm in need of electrical upgrades? (High-output alt plus wiring to go with it)

I don't know what the signs of needing to upgrade are... No interest in running a wench.

All lights except tail lights, daytime running lights and reverse are LED including cab lights and headlights.

Any input is appreciated!

 

Put a Voltmeter on your battery terminals

Load all the electrical load don`t forget blower motor

For those that don`t speak the language load the electrical system means turn all your electrical goodies on.

See what voltage you have .

Now you need to take into account the condition of the trucks charging system

Poor Connections not even a up grade will help

 

Yep did that the day after I posted and found ~13.9v at idle and after full load (all accessories, including AC, stereo loud, and a phone charging from cigarette lighter) and got 13.54
