I am about to install a new system into my car and i have a few questions on what I'm going to need to do wiring wise. I have two 12" db drive subs (1500watt max a piece), one 15" db drive sub (2000watt max), two 1000watt max db drive amps, one 1500watt db drive amp and a new box that i was about to build. Now i have a few questions on what i need to do. First i was told I'm going to need a new battery for all the amps and i was wondering if a kinetik 1400watt battery would be enough or would i need a 1800watt? Then my dad asked me would my alternator be able to handle both batteries then i was like fuuuuuuu so can a 2005 honda civic lx sedan factory alternator handle that kind of power? Lastly I needed to know would i need to use 4 gauge wire or would i need 0 gauge wire because i was told that i might need the 0 gauge but would it be ok to use 0 gauge wire to the battery then 4 gauge to the amps? As soon as you can get back to me with the answers would be great thanks

4 gauge is enough, the alternator and battery should be able to handle it just fine. Those power ratings are at max power so you will never reach that under normal conditions so I would just stick with the alternator you have. You may want another battery if you are going to be using the radio with the car off and running the subs. You can install a switch to shut off the amps when the car is not running to save the battery if you want. I do this cause I listen to my radio on my breaks at work with the car off.
