Audio Systems: amp cd player, rca cables, owner manuals

Question
when U run ur rca cables from ur amp to ur cd player U will plug ur rca to rear output right

Answer
What?  I don't understand what you are asking.  Could you give me the manufacturer and model number of the player and the amplifier?  Then I can give you an answer.  All players and amps are not the same. You must also tell me if the amplifier you are connecting to is for full-range for subwoofers.

If you are good at searching on the INternet you can find the owner manuals on each product and connect according to the diagrams that are always given in the manuals.  

But, let me know if I can help further.
