2014 Hyundai accent water leaking around front and back window.

SOURCE: Left side only speakers stopped working for a 2002 Hyundai Accent

you probably pulled the left speaker wires apart when trying to get it out. there should be enough slack in the wires to pull out or they wouldn't have been able to hook them up. the only way to fix it is to take the player out. if you don't think you can do it have someone who can do it. ( the wires might just be caught up on something, try wiggling a little to free them)

I use to have a Hyundai Pony once, there was no cable there.
But still you need to remove the inside cover etc. to get there.
