Hey guys, I have an '06 Spring Edition HHR with what I'm assuming are a factory head unit and speakers. My speakers have gone in and out since I bought the car last July. I've ordered a cheap set of speakers to replace the stock ones, but I've also been told that my head unit could be going bad as well. I would like to replace it with something that has Bluetooth and possibly an equalizer. I know nothing about these things, so I don't know what would be compatible in an HHR. Any advice?

Well there are many options, first I suggest you simply replace the speakers to test and prove that theory , then if necessary replace the HU.
As to what all you will need there are a number of threads about how to install different HU's
BritJoe had a good one a year or two ago.
