no start after stereo install

[aama1987]

installed jvc headunit in a 03 corolla. everything was fine, started, alarm working fine. then a few hrs later i go to leave & my alarm wont respond. no blinking light on my dash, no sound. Next it wont start, no gauge lights but my dash lights (oil, seatbelt) come on. everything has power, radio works fine. what is going on?? i checked fuses, disconnected the radio, disconnected the battery, still nothing.

probably dead battery?

how is this possible? its so easy to install a headunit, you prob shorted something out...prob jumping the wrong cables...but ya first check the battery

could be that you didn't secure the wiring properly. you may have exposed wire that shorted your car.. i hope you can find the source and fix it
