Cable for subwoofer

by tnguyen92 / March 19, 2007 1:58 AM PDT

Hopefully someone can help. I am installing a new 5.1 system for my house and am having some difficulties with the subwoofer connection. My house is prewired for the speakers and the sub. The sub connection is in the opposite corner from my receiver. It looks like the cable is a coaxial cable. I've never used another cable, other than the cable that comes with the sub that comes with the RCA jacks. Is this the same type cable?

I went and got some adapters and fit some RCA jack and hooked things up, but my subwoofer did not work. Maybe my connections are loose, but I wanted to ask before I spend more time and money trying to get this working. Please let me know if you have some ideas. Thanks.

I think it's an RCA jack.

OK, I assume that it is a powered sub.

You need audio cable that has RCA plugs on it, hook one end to the Sub RCA jack on the receiver and the other to RCA input jack on the sub. John

I bought RCA jack connectors that fit onto the coaxial cable and then I connected the cable to the sub and receiver. I didn't get any sound out of it.

My question is, can I use a coaxial cable as an audio cable or am I climbing up the wrong tree? I'm not sure what the difference is. I normally just see coax cables for video.

If I can use the coax cable as an audio cable, then there might be a break in the line (it's all behind drywall) or maybe my connections are loose.

Audio cable is coaxial, but designed for audio frequencies. RF coaxial cable will work for audio, but not the other way around.
Try running a audio cable across the floor and see if the sub works. John
