Sorry if this is a repost.

I am trying to wire a Casablanca CD54 head unit to a single channel subwoofer amp to a single voice coil subwoofer.

The head unit has an RCA out labeled sub out but it is only 1 connection. Then there are front right and left and rear right and left RCA outputs as well. The RCA cable of course has right and left. Do I just hook up the one connection to the sub out line or do i use a pair of the other outputs?

Thanks for any help.

 

Sounds like your sub out is mono. You need a one-male-to-two-female "Y" adapter.

Then you can use your Sub out and retain any sub level control in the HU.

 

haven't heard of a casablanca headunit before


Edit: God Bless Google

 

If it's named after a city, it has a blue dot on it.

 

makes sense
