Sound System Wiring, What am I doing wrong? Options

[94CELICAGT_98584]

Ok I have this Kicker 1600 watt amplifier in my car. I originally hooked up the whole thing in my car but it was cutting out when the bass hit because the battery wasent cranking enough amps. So I continued to only hook up 2 of the 4 channels. That worked out...then yesterday I went to Autozone and bought a battery with more cold cranking amps. I then hooked up all the channels of the amp and it worked just fine and the bass was hitting twice as hard. About 5 minutes later I could smell burning and I saw smoke coming out of my box. I dont know If I wired something up wrong or what but I need help fast. In side my box there is 14 guage speaker wire and running into it there from the amp is 10 guage. Could the thin wire inside be burning or what? Here is a picture to help.....PLEASE HELP

do the subs still play, was the smoke coming from the inside of ur box, cuz that sounds like your burning up the subs. what subs cvr 10 12s dual 4s 2s and what amp 800.4 900.4. that would help me at least try to figure it out.
