I need to move my powered Velodyne subwoofer from the front of my living room to the rear, so I have been researching ways to accomplish this.


I already have a box on the back wall with my rear channels dropped in it, so my idea was to purchase some more 12AWG CL2 in-wall speaker wire, run it to the box and terminate my own RCA ends. But upon further reading, I find threads stating this is bad, some stating it is ok.


I want to do this right, so I see everyone suggesting RG6 with F-to-RCA ends, but I cannot seem to find the ends to attach to the RG6.


I am using a keystone wall plate at each end, so I'd like to terminate to that, and then just run standard subwoofer RCAs from the receiver to wall, then wall to powered subwoofer.


Thanks for all the help.

For subwoofer you will want to use a coax based cable assembly with a 75 ohm rating. This can be either RG6 or RG59, with the RG6 being thicker, better shielded, but likely less flexible.


Instead of trying to adapt F-type connectors to RCA on keystone jacks, I'd simply buy an RG-6/59 based cable with RCA connectors on each end and then basic RCA coupler type keystone jacks.

Whatever you do, you don't want to use speaker wire for a low-level signal. Not only is the impedence wrong, but it won't be shielded.

The characteristic impedance of the cable is not important. There is no impedance matching taking place, the source is bridged with a high impedance load.

There is no need to use 75ohm cabling for analog audio such as subwoofer use.

The impedance is irrelevant in both applications. But you are right, speaker level is unshielded and if there is any noise around, it'll end up in your signal. You're just asking for hum problems.
