Subwoofer coax?

Question

i have a powerd sub that needs an rca input but its on the other side of the room from the reciever so is it possible to run a coax to a lowvoltage outlet back to rca? ive seen the adapters online. if it is possible does it matter wich coax i use?

Answer 1

It sounds like more trouble than it's worth.  Just get a good quality RCA interconnect cable and connect it between your powered sub and your receiver's sub pre-output and you're done.

Answer 2

You are fine running it 70 feet.  Standard RG6 or RG59 can go easily 250 feet without any signal loss.

Answer 3

Sure just add F-connector to RCA adapters to a standard coax video cable and it will work fine at 70 ft. Or if you want to get fussy see the article at the second link.

Answer 4

Running through AC power outlets with a convert is a really BAD idea.

The most common source of noise in your electronic gear is 60 hz hum because of all the AC power. And subwoofers  - amplify 60 hz sound very well.

Move the sub to the front of the room near the TV (simple solution). Or buy a long RCA cable and tack it under the base-board.
