2005 Chevy Colorado door locks and automatic windows

All door locks and automatic windows where working fine until I installed an after market stereo and new speakers in each of the four doors. Now non of the doors will lock or unlock either by remote or manually and the driver side window will not open or close. All three other windows work fine. I put everything back together as it came apart and modified nothing behind the door panels. The remote activates the interior lights as it should as well as the blinking head light when attempting to lock but will not activate the door locks as it should. What could be wrong? Please help!
