What is this??, stereo is going to blow up Options

[Silver99GT]

If there is on thing I have absoultly no idea about, it is speakers stereos and how they hook up. here is my prob:
I got a new cd player for the car, so I have the guys where it was bought hook it all up. Next thing I notice the 10s in the hatch aren't sounding the way the used to when the factory radio was in. So this kid at school was like "trust me I know what I am doing I'll fix it" Next thing I know the amp is running all hot and stuff. So I have another guy tell me that the first guy f'ed it all up and he did some crap... now when I take the face plate off, holy crap, the noise that comes from the speakers is deafening I don't know what that is? Can some one hook a girl up with an idea of whats going on and maybe how to have it fixed?

Take it back to the place where you bought it. If they are a decent shop they will have no problem fixing it for you. Any good shop knows that keeping the customer happy is number one. If they won't help try another shop they may charge you something for the time but since they are fixing something they didn't do it's understandable.

If you still can't find someone to help let me know and I'll see if I can help. It pretty hard to explain if you don't know what you are looking at but I'll do my best.
