I just installed a Alpine 7995 HU in my car. There is no amp built into the HU so I am using a 5 channel amp to power the speakers.
I was checking all of the connections and everything seems to be okay. I turned the power on and the tuner works great, however, I stuck a cd in and the HU reads it, acts like it is playing, but there is no sound.
So if anyone has any advice on what I may have done wrong, that would be great.
