HOW TO HOOK UP AUX INPUT ON A CLARION DXZ665MP CD PLAYER?

SOURCE: clarion dxz665mp cd player

I think you connect the wrong remote wire to the subwoofer amp.
This cd player it has 2 blue remote wires,one is for PWR ANTENNA (BLUE ONLY),when you insert the cd,this wire cut out the pwr,so,is when your subwoofers stop working.
The other blue wire is the REMOTE (BLUE W/WHITE) Wire,this is the one you need to connect to the Amplifier.

Let me know if work
Thank you

Provided that you're using the same cable you used for the last changer, it sounds like the new changer is defective.
