    If your total system power is a 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 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.

    A cap is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing esle. If the current isn't there, a cap won't help.

    A second battery is never a good idea as it's just an added strain on the alternator unless you plan on running the system with the engine off.

    Here is a guide that will calculate what size alternator and power wires you need as well how to set the gain http://www.datafilehost.com/download.php?file=6d26...

    You'll need Microsft Excel to use it.

    i go with optima yellow or blue top. but if u want to spend more money and get the same if not less go with kinetik batteries. my buddy at usaci world finals this year gained .1 of a db by putting a yellow instead of his kinetik. and he hit 162.7 db. just to put this out there not dissing on anyone i ran 3900 watts from a d2 shredder off a red top on a stock alt and never had a prob i could hit with engine off for over 8 min and still start with 12.9 volts for over 2 years . just to put it out there. i think its a hit or miss if u running street beat and need a after mark alt or not. thats my say.

    i'd go with a Kinetik. however before i get a big new battery, i'd get a big new H.O alternator.

    good luck
