I have an ext cab K1500, with aftermarket Rockford Fosgate speakers wired to a 4 channel amp, also have a monoblock amp for 2 subs. neither amp is getting power. The radio powers on fine, just no audio at all. Thoughts?
Thanks

I have my amp wired directly to my aux. battery and the signal wire to the head unit.Amp comes on when I turn the radio on.

I didn't explain that very well,did I?
About the same as I did, I think. 
Audio issues are kind of like computer issues, hard to explain and diagnose over the internet. Unless you've got it in front of you to look it, things can be tough.

OP,are you sure the amp is wired to a power source?

I would find a way to intercept the speaker outputs from the head unit into a pair of cheap speakers. This could allow you to check for the presence of a signal from the head unit .
You could also find a signal source to plug into the amp input instead of the head unit. Inject a tone and you can find out if the amp is working. My bet would be something blown in the head unit .. is there a fuse on the output?
An easy thing to check would be the settings in the head unit. Some of them have settings to enable/disable the pre-outs, and some of those will enable/disable the remote wire signal in conjunction with the pre-outs. Another thing that I've seen (although very rarely) is the internal fuse in the head unit for the remote wire blowing. That one sucks, as it's not something most people can replace themselves.
