I did two fronts this Summer on the '08. Now it is Winter and I noticed one of the front door speakers is shot on the '05. I am ordering two because I am expecting the other side to fail as soon as I fix the bad one. I have an '05 Sunfire and all speakers are original. What gives with these Cobalts?

The door speakers on the cobalt are unsealed from water. Many autos Inclose the door speakers in a plastic bowl to keep outside water off of them,

What kind of speaker did you replace them with? If they were stock replacements, they'll absolutely go again.

Many aftermarket speakers don't use a plastic cone and thus are considered "marine grade" and should provide years of trouble-free service since they can handle being in a wet environment. I don't like the baffles that keep the speakers dry because they absolutely obliterate bass response.

It looks like it was a water problem because the magnet was rusty, the speaker cone was missing a large section where it attaches to the frame, and the connector was wet. I see the water shield covers everything except the speaker area. I had a stock GM speaker on hand so I just replaced it with that. The original lasted 17 years so I guess I shouldn't complain. I was amazed to see that GM is still using the same manual window crank retaining system that I have on my 1968 Firebird. The same tool pushes the little clip off and the handle slides right off. I guess it worked well for 40 years so why change? The best part is that the Wifey didn't even know the speaker was out. :sleep:
