Hi, I have a 99 civic ex sedan with stock HU and speakers. I have found out recently that my left rear speaker is not making any sound but the other three work perfectly. I open the trunk and check the wire, connector and they seem fine to me. How can I located the problem? Anywhere else I should look into? Please help guys, thanks in advance.

 

Do you own a multimeter?

 

I don't. But I can borrow from a friend.
