Max volume... only hear one speaker
 

ok well my deck got fixed after an issue, and i know it works as they tested it at the store. the deck worked before in the car and now im having an issue. first off all my connections are good (+/+) (-/-) and the deck turns on and counts the cd playing. i crank the volume to max and i can only hear my rear left speaker and its very faint and crackly. ive checked my connections to each speaker (from the wiring harness to the actual speaker) and everything checks out ok. anyone got any ideas?? im kinda stumped

check the settings on the stereo itself?

yeah, check to see that the audio is balanced. you can check that on your deck. someone might have changed it to that one speaker

checked everything, might just be 2 front blown speakers.
