Help Please. I got the wrong cables - but will they work?

[FirstPlasma]

First let me say Hi to everybody. This is my first post.
I upgraded the equipment in my Family room so I am moving the old stuf to a "spare living room". The speakers I am using connect to the amp via a single dig rca cable from each speaker. I needed to extend the lenght of these cables to reach the amp so I purchased 25' dig rca cables. (or so I thought lol) I just realized I got the wrong cables! I got subwoofer audio cables!

((Tried to post the link to the cables I got but the forum wont let me since I have less than five posts - sorry.))

Question is... will they work for full range speakers or is there something about them that makes them for subwoofers only? Do I need to just hang my head in shame and go get the right cables?
Thanks to all Very Much!

Hi FirstPlasma welcome to the forum.

You will be fine with those cables. You can interchange a Digital Coax RCA and a Sub RCA they are both 75ohm cables and will serve the same purpose.

Just out of interest what type of powered speakers are these?

Thank you Thank you Thank you

Again.. sorry I can't post a link... but they are a speaker system from Logitech. I use a media center pc in the setup for this room and the logitech speakers - being computer based - plug in with a standard green computer audio plug. Things are no longer done this way with the media center pc but it is an old set up that I have not put to much money into. (My new media center pc uses HDMI)
The logitech speakers are fine for a second theater setup but I would not recommend them for your main room.

Thanks again for your reply. I am very very glad to hear that I can still use these cables!
