just installed AVH-P4000DVD HU and can't get sub to work. Anyone had this problem? What did I do wrong?

 

its probably the remote turn on for the factory amplifier. the remote turn on for your Nissan harness is wrong ( im pretty sure Metras 7550 has it wrong ). more than likely you have to hardwire it. just find the color on the internet for the remote line on your factory harness and tag it to the blue/white wire on your pioneer harness.

 

Will try and see what happens, thanks for the help.

 

mine is the same .. i hv no idea..and end up just leave it in the garage

 

I've searched all over the net for the digram with no luck. Any idea of a website that would provide the info?

 

yeah man when i get to work this afternoon ill look it up, but i think there is a wiring diagram in this forum also.
