    This POS+ wire connects the two batteries' positive posts. This wire allows the rear battery to receive the charge from the alternator, just like the front battery receives. Without this wire, the rear battery would not maintain a charge. WIRE 1 should be at least 1/0 awg wire.

    To estimate the listening life of your battery or determine how much charging power your second battery should have, use the following equation. 10 X (Battery capacity in Amp Hours) / (Load Power in Watts) = Running time in hours. If your batt has a 75 AH rating, and your amplifier draws 1,000 Watts, that would be calculated as: 10 x 75 / 1000 = .75

Wiring two batteries in one car? - SSA® Car Audio Forum

    Depending on your system demands, from my experience dual runs of 1/0 +&- from battery to battery is worthwhile. Two batteries wired in parallel can discharge much more amperage than what a single run of 1/0 +&- or a 300a fuse can handle. Just a thought. If you run it like you only had one bat the load would be the same.

    In this case you can use the formula I (current) = P (power in watts) / E (voltage). Adding a battery is the quick solution to this problem, but may not be the best solution. For example, a 2000W RMS amplifier will potentially draw up to 240 amps of current depending on the design and efficiency of the amplifier.

    Just run parallel, + to +, - to -. For the fusing, the safest way is to put a fuse between each battery. Me personally, I would only fuse the long run of the front to rear, then keep the rear 2 batteries non-fused. On 9/10/2012 at 4:43 PM, TylerParrish said:

Wattage Chart - XS Power Batteries

    With our wattage chart below, the choice has never been easier! When using only one battery, refer to the “Primary” column; when using a second battery as a supplemental battery, refer to the “Secondary” column. When replacing the original battery and adding supplemental power, use a combination of the two columns to arrive at the desired level of power needed to satisfy any …

    An isolated battery dedicated to the audio system is the best way to set up an electrical system, short of installing two alternators (often not an option). A real battery isolator (diode based) is the way to go. It will allow current to flow from alt to battery 1, and alt to battery 2, but current cannot flow between the two batteries.
