Stock 140 amp alt question


Recommended Posts

Posted

My car comes stock with a 140 amp alt and big three. My battery see's 14.2 to 14.4. My question is will that be enough to run a 3000.1 and a 800.4 amp or should I look into a h/o alt and/or a 2nd battery?

try a few extra batts first, full tilt i stay around 13.3 with 2 D2400s on a stock 120amp alt, with a dc 3.5k @ 2ohms clamping 1200, and a 300.2 on my mids and highs

Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Why would you EVER WANT flex?
huh?...flex is what can make the lows lower and more air being pushed correct?

depends what amps.

you're not going to be able to support 4000 watts on a stock alt, if the amps ratings are true.

Okay another question.....My car uses a vented battery. Will it be okay to add a non vented battery (agm) to my system?

I honestly don't know if you'd be okay or not but it's recommended that you stay in the same battery type. Don't be mixing all different types. If you want another batt, either get 2 of the same style and replace 1 and add the other, or get the same type as you currently have

Kranny there is a vent tube that runs from my battery out the bottom of my trunk. I appreciate your concern though. I guess i could buy another battery and splice the vent tubes together.
