Hi, there,
I've been scanning the forums for days and have been unsuccessful in finding
any sort of link to tutorial/instructions on how and where to install speakers
in the rear of my 2009 2LT HHR.
I haven't done anything like this in decades, so I figure by now I probably
know less then I did before.
Can anyone point me in the direction of how I can be introduced into what
I'm in for, what my options are, etc?
Thanks in advance.

 

Aren't they in the doors?? Just pop the door skins off and it should be easy go from there.

 

Did you check out the stickied threads at the top of the audio forum? Good info and ideas there.
