1700 watts off one battery?

[Braindead]

I'm going to be running a 640 watt 4 channel amp and a 1100 watt monoblock, could i run 0/1 gauge off my battery to a distribution block without any troubles? Would i want to do the big three? Also i have a stock Denso alt, and it says 164AA on it, I have no clue what that means.

The last resort would be a HO alt, its just not in the budget. Maybe an extra battery? It'd be kinda ugly considering I have a jeep...

i'd go with a second battery myself, but you may be able to get away with one big one........ your lights will dim at higher volumes but

you'll need more electrical to run that at a decent level.

2001 limited, V8.

So I wouldn't need another battery? Maybe just a really good one to replace the one i have in there?

You will need a second battery, atleast 50ah just for your audio system, also invest in a stinger voltage meter to watch for major voltage drops.

Could I just get a battery that's 50ah better? And do the big 3?

adding a second battery could make things worse

batteries are expensive these days. its $100 just for a cheap auto batt. a good batt may be $200+ but a HO alt is $400+

I just checked under the hood, I have an autocraft gold that says it gets 1000 cranking amps @32 degrees. But it's summer and it hits upper 90s regularly here in SC even though its been raining like hell this summer. So maybe it gets around 800 amps now?

Alright apparently its a **** battery. ****, I don't know how i can afford this now... Guess I'll just take it really slow

on a daily system i try everything stock and see what happens. then if need be upgrade wire. then batt. then alt. you can run 1700 watts with your vehicle as is. just not wide open all day.

ive run 1500 watts on a 85 amp alt with the cheapest walmart batt there was so.. but it would shut of my car at full tilt.

what brand amps do you have?

 

[Side Show 10+ year member]

It'd be about 3/4 volume in 15 min bursts. I'm mostly worried that I wouldnt charge up my battery with what was lost and eventually kill the battery. Some dumbfuck tried to break into my car with some jeep key, and broke it off in my lock so if my battery dies theres no way to get into the car. Also sometimes I get to school early and would run the system on the battery alone. How bad would this be?

They're going to be Hifonics, I'm 16 with a sh*tty job, but I'm going pretty far with the speakers, wiring, and just put in my Kenwood last night. Its a good feeling man. RF 3-way 6x9s in the front door and 2-way 6-3/4s in the rear door. Fi SSD sub.

if you run your system a lot with the vehicle off then a second battery will come in handy. both batteries need to be the same kind tho.
