Just because they look new doesn’t mean they work.
Have you even tested the speakers ? Tried new ones ?

 

The base radio had paper cone speakers, these deteriorate over the years and stop working or work intermittently. A very common problem

 

Condensation yes but not from the AC, The side window seals don't work well and water gets into the door that turns to vapor in the heat, then gets into the coils that corrode.
Check for resistance between the poles of the individual speakers.

 

I inspected the passenger side front door speaker no sign of deterioration or corrosion, they look brand new! I did not check the driver side yet
I only get sound out of the tweeter passenger side!

 

the paper cone is in mint condition as is the connection of the wires!
this hhr only has 70,000 miles and I’m the second owner

 

So after reading your last 2 posts then the answer is No, you have not tested or tried replacing the speakers. Again, saying they look good means nothing. 13-14 year old car. Mileage doesn’t matter. Not sure what answer you’re looking for but it’s obvious you don’t care for the ones we’re posting.
Good Luck.

 

I’ve seen paper coned speakers off the shelf fail due to internal moisture in the magnet, outside looked great !

 

okay my humble apologies
I bought a set of speakers and sure enough I now have sound from my speakers
but I don’t understand why all four speakers didn’t work and I do understand the moisture for the front doors but the rear doors have no windows!
thanks for getting me through this 🙏

 

In my opinion moisture may hasten the demise of those POS speaker but is hardly necessary for their inevitable self-destruction. Your experience is pretty good evidence of that.

The speakers fail one by one but a typical non-audiophile owner may not notice until the last one dies. The failures are an accelerating cascade because as they fail, the operator turns the volume up to compensate, hastening the demise of those remaining operative.

These speakers are less vulnerable at low volumes, but with large displacements of the voice coil, arcing occurs, frying the coil insulation and eventually burning through the wire, resulting in an open circuit. At least contributing if not completely responsible are transients from the anemic low-power base radio. SOURCE: Just my opinion, but I’ve dissected a few failed specimens. Have pics, maybe I can find them, maybe not.

Transients can damage any speaker, but these OEM speakers are inherently vulnerable in my opinion. If you keep the base radio, just don’t play it loud, even after replacing the speakers with aftermarket. If you like loud, install a higher wattage unit or add an amp. Larger speaker wires also help avoid speaker damage. The stock ones are a little small for loud operation.

 

The base 6 speaker system has the same HU as the Pioneer 7 speaker system, the subwoofer is added along with an amplifier and the Pioneer speakers are far superior to the base speakers.
in this case 4 new speakers will perform better
