Just bought a 2007 Silver Cobalt SS (non-supercharged) yesterday. The stereo turns on but no sounds comes out. Unfortunately, the dealer said to bring it back Monday so they can fix it. So, I'm bored reading through the manual and see that the amp has its own fuse (of course). So, I go check it and it's blown (20A). I go get a replacement fuse and put it in. I immediately get feedback coming from the rear sub and the fuse blows. Any ideas?

put the stock one back in. if you changed it, and it's blown, there probably going to blame it on that. other than that, let them take care of it. it's a brand new car, not your responsibiltiy to try to fix it.

First off, they already know that no sound is coming from the stereo. So, they know they're on the hook to fix it. I was just hoping it was something easy or obvious that I could fix.

yea, i'm not too sure about the electronic side of things. i wouldn't even know where to begin to tell you to look. some of the guys here are much more experienced with that kind of thing, it's still early though, i'm sure they'll be on later.

To me it sounds like a bad factory ground. It has happened to me in the past with amps. Either factory or aftermarket. The ground makes a huge difference.

I'm in the same boat as you, I'm pretty ignorant when it comes to this sort of stuff. Oh well, I'll let the dealer figure it out.

sounds like a short to ground....if that's the case, going to have to test the circuit and find the damaged wire/connection

Dont mess with it, it might be a bad ground, or a faulty power supply in the amp, or any other of a million things. Leave it alone, not worth messing with when you can have them fix it tomorrow.

I doubt it would be a bad ground. I think if the fuse keeps blowing it's a power supply wire that is grounding out causing the fuse to blow.

ditto on that

Took the car in and got it back within hours. They did a test and the amplifier was bad. So, everything works great and my wife loves her new SS.

Thanks for everyone's suggestions!
