  1. First off, 1996 Honda accord station wagon. 329 amp hairpin alternator. Big 3 is completed with 0 gauge wire from sky high. 3400 XS battery up front. I am keeping the air conditioning. Could possibly consider cutting a hole in the hood to fit a 2nd alternator *in the future* but not now. What i am trying to learn, is how to figure out how many batteries I need to sustain X voltage. I know about amp hours. I know my alternator came with paperwork saying it is rated at 4,890 watts. What I don't know, is how to figure out how many batteries I need once I go above that 4,890 watts. How do I figure out how many batteries I need for 6k watts? 10k? 16k? 20k? I know I could just throw 30 tractor batteries at it, I don't want a hand out. I want to learn the math behind figuring out how many batteries I will need. Any help is greatly appreciated.
  2. so i recently noticed the other day that one of my subwooers is playing harder than the other. i first thought that one wasnt playing at allbc i couldnt hear nor feel it moving. no today i toook outmy box and checked all my wiring and nothing was wrong. checked my rca's and nothing was wrong. i then swapped the subs and cranked it up and the problem stayed on that channel. then i swapped the rcas around and the problem still stayed in the same channel. the subs play just fine on channel 3 but veryyyy low on channel 4. both channels are using the same x over and gain. so could it be that the channel that is playing low could have a short n the amp or what? help please
  3. Im new to car audio so excuse the noob question but when getting the voltage required for the gain ( V=sqrt (P*R) )should I use my amplifiers rms wattage or my subs rms wattage for power (P)? I ask this because my amp is rated for 500 watts rms and my subs are 400 watts rms, so I thought using the amps wattage might overpower the subs? I will be using a multimeter for setting the gain.
