Clarion DXZ545MP

Anybody ever ran across a situation where when you hook up and external amp to a head unit for all speakers and the tuner is the only function that outputs sound?  I have been working on this Rodeo and finally got the Metra 70-7713 harness, wired it to the Clarion deck, which was previously in an Oldsmobile Alero, in which it worked fine, and plugged everything in.  Tuner works great, CD player plays the CD but no sound and the XM commander works using the RF modulator but not the RCAs.  I cannot think of anything.  I reviewed the manual just in case there was a certain setting but came up with nothing.  Any ideas?

You got the antenna output wire on the deck hooked up as your amp remote wire, gaurenteed. Just switch so that you are using the amp remote wire off the deck which is blue/white, right now you are using the blue. Very common mistake and easy to do.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
