I just bought a 06 SS.........The front two speakers are the only ones that work and its super quiet when turned all the way up.......any suggestion?

 

Excellent choice of automobile.

Is the amplifier present in the trunk under the shelf? Check the fuse for the amp? It's in the right kickpanel fuse block.

 

I checked the fuse and its good.......is the amp blown?

 

Not sure if this is the same issue I had, but if it is, there is an orange wire inside of a cluster of wires leading under your interior to the trunk. That orange wire provides power to the amp, so when it splits you will get nothing from it. I would try checking to see if you can find a split somewhere.
