Chevrolet: 2002 Chevy Camaro Z28 will not start., chevy camaro z28, 2002 chevy camaro z28

Question
Ok, well i decided to try and put a Bazooka BassTube in my car myself. I wired it all up, but didnt get it to work. So i took off all the wiring that i did, and when i try to start it up, it wont start. It does turn on the stereo, and gauges turn on, but when i turn the key to full ignition start, it seems to die down. Fuel gauge goes back to Empty, Miles gauge turns off, Battery gauges doesnt even mark halfway with power, and i also have the Security light flashing. The only thing i did was remove the battery, to hook up the basstube power(red wire) to it. I did also remove the factory stereo, to see if i may be able to hook any wires up to it, but didnt do nothin else but hook the stereo back up. got any ideas of what the problem may be?

Hi - is the battery dead ?  did you try to jump it. I'm not sure but on some models the computer can be adj. threw the stereo. you might have set the alarm system off and it could have put the car in a safe mode. I would try to jump it. but first remove the pos. post than put it back on. than try to jump it.
