Rear speakers dont work

Hi ,

I have a 94 camry and the rear speakers sometimes work and sometimes dont. Is there a connector somewhere which i can check for loose connection ? Or can there by any other problem. Any help will be appreciated.

Check inside the trunk.
Perhaps something carried inside the trunk knocked one loose.
Connectors are obvious if you look in there from underneath.

From the trunk everything looked Okk. Do you think i should go ahead and open the deck panel in the rear (behind the back seat) and look ? Do you know if there are any connectors there ??

Thanks !!
