Did you use the RCA outs

Did you use the RCA outs.
How does the metra harness run the Inputs to the Hi Fi amp?
The Hi Fi amp is only meant to accept 5 volt differential signals.
If this thing hooks it up as common ground single ended Inputs it won't work. You will need a adaptor that converts to differential inputs.
Do you have pinouts of the metra harness and the OEM system.
When you say he checked it out do you mean measured with a meter.

The harness may assume the base system is
what you are working with not Hi Fi.
