Trying to return the interior to an original radio and integrate Bluetooth. Picked up a CR-915 on eBay that has a tab over the amp port. I snapped it out and there’s nothing behind it. My 940 does have an amp. Not sure what my options are. Does anyone know the radio model that has an amp port? Thanks

 

Hey there, as best as I can remember, the stereo drives the dash speakers directly and the door speaker output connect directly to the underdash amplifier. The amplifier then powers the door speakers.
The underdash amplifier is under the driver's side knee bolster.

 

Turns out the correct model is CR-814. It has the correct female speaker wire connector and ports for amp, CD and EQ. Now I have to reverse the loom conversion back to stock. I also need to find a reputable place online that does repair and Bluetooth conversions.
