electrical for 5000w rms

[ally]

Pretty soon I plan to run about 5000w rms in my daily driver honda civic.

I need to know if my electrical will suport it.

I dont want the best electeical I just want to keep a good voltage higher than 11 volts

I will have big 3 in 0 gauge

dc power 180amp alt 130 amps at idle, charges at 14.9 volts

optima red top under hood

2 runs of 0 gauge,1 run pos one run neg

1 run of pos 4 gauge to the trunk other 4 gauge will be grounded from the trunk

2 optima red tops in the rear

8anyone?

Mehh. You're going to need a bigger alt (250+amp), I would also do more than 2 runs to the back. 2 batteries you could get away with if your alt is really strong, I'd still do 4 in the back though.

Look into some XS power batteries, you will for sure need them, for backups and for main starting battery. More than one run of 0 gauge to the amp(s) is going to be a must and you will need to go beyond just grounding to the chassis, you should run ground wires from front to rear also. 5K is a lot lol, i have 2K with nearly the same electrical you described and I still have issues with voltage lol.

11v is a shitty goal. Like, going to kill that 5k goal. 12.5v is the lowest you should EVER see in a daily.

Get a 200a+ Alternator

Upgraded stock location battery

And 2 Group 31 AGM Batteries for bank

This will keep you in the 13s.

All in all, will cost you about 1000-1200 bucks.

You may want to look into some bigger batts, those red tops are kind of small.

I think if you upped your wire to two runs of + and - of some decent 1/0 OFC, with that alt and batt setup you should be o.k. for the time being. Def get more wire though, and look into larger batteries.
