HALP - No sound from front door speakers
Alright kids, I have a 2008 Cobalt LS w/ STOCK radio, no OnStar. I went into my car the other day and I had no sound coming out of the front door speakers. The rear speakers work fine, but am still puzzled on why they stopped working all of a sudden. I already tried the levels on the radio, but still no sound when I put them to the front. (no door chime either) Im thinking is a head unit issue, but I don't really know if there is a fuse that needs to be replaced for the front door speakers inside the stock HU?
I did have an amp installed a few years ago, but that was only for a sub in the back. So this shouldn't affect the front speakers.
I do listen to music a a decent level w max being nothing more than 75%, but nothing that I would think would blow them.
From my understanding, if a(1) speaker was blown, the other one should still receive sound right? What I find weird is that how they both stopped working at the same time.
I know i can go aftermarket, but I like the design and ease of the stock radios.
Plz chime in if you got any other advice...
