The Most Power!

[Eggroll]

Whats the largest amount of watts/rms that is recommended without changing or adding a new car battery or alternator?

(Btw what do you have to do it you are over that power limit?)

Not really much. The alternator on said vehicle is designed for the max amp load the car can draw. I wouldn't do over 800rms

depends on the vehicle....normal above 1000rms

It's not quite that simple. The stock alt for a vehicle is always sized with a reasonable degree of overhead. Knowledgeable mechanics I've dealt with say 50-60% more current available than what is required on average. That allows the alt to run relatively comfortable and last several years.

Sake - there's not a specific number that's guaranteed to work or not work in any given car. There are many variables that can effect the outcome.

In most cases - 1000w seems to be a reasonable limit, but there are plenty of stories of people having a lot of trouble with that.

On the other hand, plenty of people run 1500w+ stock with no problems to speak of.

The only true solution to a struggling electrical system is a high output alternator.

Batteries are secondary, and capacitors are useless.

Okay so I would need a great alternator?

Depends on what you plan on running.If around 1500 watts or so id start with a good agm battery.

I gi made them fit for all my cars.just check how much space you have for the battery in your car and go from there.
