Will my electrical system hold

[Diablo6699 10+ year member]

I have a 1994 toyota 4runner with stock alt, but new battery. I already have a 4 channel alpine amp running fine, but if I add a class AB 700 rms 2 channel amp with 4 gauge wiring, will my electrical system hold up? I dont mind a little dimming in the headlights, but i dont want it to drain my system. does anybody know?

Depends on your stock alternator.

Do the big3 and you should be fine however wiht that much power.

I bet you will be fine. My stock alt and even stock BATTERY is currently running the setup in my sig with barely any headlight dimming except during unnaturally long deep bass notes (i.e. synth bass), and even then its not bad, and I also have 4 ga wiring. Still suggest bigger wire though, I'm running into annoying shit looking at upgrades and I'll probably end up upping the gauge.

my 4 channel has 12 gauge to it, will it affect anything if i give it 4 gauge
