Does a capacitor actually give enough power for 2 1000 watt amps?
If your total system power is 1000 watts RMS or more, you will need to: 1. Upgrade the alternator to a high output alternator 2. Upgrade to a heavy duty deep cycle battery 3. Upgrade the “Big 3” – that is to replace (or add to) the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 2 AWG wire. Failure to do this will result in you replacing them anyway as the alternator will eventually fail. Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php… A second battery is never a good idea as it’s an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off. A capacitor is only good so far as the audio system isn
