Answers: you need an isolator this will allow your alternator to lone charge one battery at a time. hook up your nouns battery as the leading battery and your starting freestyle as the second battery and your alternator will maintain you sounds and the isolator will never let your starting battery-operated drain to low
If your total system power is 1000 watts RMS or more, you will need to:
1. Upgrade the alternator to a giant output alternator
2. Upgrade to a heavy duty adjectives cycle battery
3. Upgrade the "Big 3" - that is to say to replace the power wire between the mobile and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis near at least 1/0 AWG chain.
Failure to do this will result in you replacing them anyway as the alternator will eventually come to nothing.
Here is a guide that will calculate what size alternator and power wires you call for http://www.datafilehost.com/download.php...
A second battery is never a righteous idea as it's an added strain on the alternator to charge two battery AND supply power for the car. The ONLY time a second battery-operated is useful is if the audio system is to be used near the car sour.
A cap is solitary good so far as the audio system isn't trying to verbs too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nought esle. If the current isn't there, a sunhat won't help. The alternator must enjoy at least 20% more amperage power than the entire vehicle and nouns system combined for a cap to be of benefit which is ironically one and the same requirements for an amp to be efficient.
