Megane mk3 twin rca outputs

[ziik]

Bought new megane and the stereo has Bluetooth connection.
Underneath where the key goes there are to rca outputs. My question is I don't want to remove oem headunit as the features are brill but want to add sub and amp , would I be able to use the twin rca to connect the amp to them ??
I have read manual and they are they for use of anything like external MP3 using twin rca to 3.5headphone jack

They are for input not output
