    should I get a capacitor?

    Just recently I took my 95 ford taurus in for service. I asked em to check the battery and alternator. They told me the alt. was a little weak. It's probably because of the 2400watt(Idk if thats peak or rms) pyle amp powering two pyle subwoofers. Some people have told me that getting a capacitor would help prevent the alternator from being overworked. Most of them said that 1 Farad is sufficient. The reason why I'm hesitant is because of what some people say about capacitors. They say that they are not worth buying and should just get a high end battery. btw, my have a the battery replaced just recently because it how many times I left the lights on, so it's not a stock.

    The capacitor is more to deliver the extra power needed when the amp and subs are working hard.

    It doesn't stop the alternator from having to work its backside off to supply the power needed for the system to run, but it can help stop some of the peak spikes that the amp can require.

    Think of the capacitor as a smoothing device, when the amp suddenly needs that extra shot of power for a split second, the capacitor is there to give that little extra. But it is only designed to help smooth those little spikes, not deliver a sustained supply of power.

    You can look at having the alternator upgraded to a larger unit if the current one isn't supplying enough power, however that does become a bit of an engineering challenge, as usually you would have to get someone to make up a new bracket to mount the larger alternator.

    No you should not, it introduces further strain on the alt.

    Correct. The law of conservation of energy states that energy may neither be created nor destroyed. Thus you aren't going to be putting any less strain on the alternator, you're just moving it around at rates nicer to your subs when they need it.

    TODO:
    -Upgrade big three wires atleast: alternator positive to battery positive, battery negative to chassis, and engine ground to chassis
    -Get a better battery (exile or optima, or something like that)
    -get a more efficent amplifiers (class D), cheaper than replacing the alternator

    You should measure the current draw of your system, and check the alternators max amperage (130A I think).
    What kind of amps do you have?

    You should get 3 or 4 caps! Would suit the Pyle hardware perfectly...

    Sorry...couldn't resist.
    My only memories of Pyle is from an surplus-everything store, 20 years ago...

    Well, to tell the truth, I didn't even heard of it until now, but their homepage is not too promising. And I think the 2400W RMS is on 18V, not on 12V

    I think 2400 watts would only happen if you ran 110V to it, and then only for a split second...
    I think Pyle rates the amps at the first power up...that 'POP' sound you hear
