  • Power Managment...

    Currently i have two Sub woofers, two amps, and a 1 farad capacitator. I'm worried about adding in another thing, ( a mini-pc)... do you think my battery and cap can handle all of that?? thanx....
    Looking for Guidance...

      The capacitor isn't going to help the situation at all. They are designed to give a reserve of power when the amp(s) need it (for example when a big bass note goes through the system, subs need alot of power) they dont provide "more power" as such.

      Best bet is to get a nice big battery - i usually go for 520CCA batteries since it is harder to flatten the bigger battery, and it is nice to have a nice lot of power during engine startup anyway. Also make sure your alternator is up to the task.

          FYI the arise ACE-865 has on the back of it.. 8-16v , 15 amps.

          Go figure.

            Personally, I hate amps, so I don't think I'd use that many.

              Well, a computer can't drive car speakers directly, so you gotta have one. Even if you have a head unit, it has an amp inside it. Nescessary evil

                Mike I'd worry more about your alternator than your battery/cap. The more things you hook up to your car's electrical system the more juice it has to provide when the car is running. Remeber that it has to power everything plus charge up all the batteries in the car. So if you upgrade anything consider getting a bigger alternator, but from the equipment you mentioned unless you are running some huge amps or playing your stereo full bore with headlights on, wipers going, and A/C cranked you should be o.k.

                  I heard that if you get a yellow-top Optima battery, you need not worry anything about batteries anymore ! Many people I know who have power-thirsty stereo setups and lcds and such use the Optima yellow-top battery. It costs around $180 I think.

                    I think a few have missed the difference between electrical AMPS, and AMPS as in audio amplifiers within this thread?

                        Remeber that the batter is there to start the car and run electrical devices when the engine isn't running. Other than that it will provide some power if the alternator is overloaded or goes out. But if you only/mostly run your stereo when the engine is running don't worry much at all about your battery. Optima's are awesome batteries, I've had one of the older red tops in my car for almost 5 years now. And I used to compete with my car stereo when I had more time. But the alternator is much more important than your battery when the car is running. Keep that in mind when you're spending your hard earned money.
