How do I connect regular two wire for speakers and connect it to a RCA type wire for the sub woofer?

Question

Ihave regular speaker wire that is spilt into two wires which twist the end , than squeeze the wire jacks on the reciver and put the wire in the holes.

The recievers come now with wire connection except for the SUB WoOfeR which has a RCA plug in on athae back of the Reciever. How can I modify regular speaker wire to a RCA plug on the end?

Answer 1

Well, this can be tricky.  usually an RCA plug would indicate a low level signal.  And twin lead speaker wire would indicate high signal level.   Many subwoofers are powered (power cord just for the subwoofer).  If your reciever has the RCA connector, you need a powered subwoofer to use that jack. Bose uses a passive sub in a few of their speaker packages.  In a passive sub system the front left and right channels (from the amp) get wired to the sub. the left and right speakers get wired to the sub.

Inside the sub is a device called a passive crossover.  it separates the high and low frequencies.  The lows come out the sub and the highs go out to the left and right speakers.

Either way there are many different packages out there to choose from.  Take a trip to a local electronics store and take a look at the different subs available.  Research online before you buy anything.  Prices can vary greatly.

Bad idea.

The RCA jack is expecting un-amplified signals. If you hook speaker wires to a RCA plug and stick it in - you will be sending WATTS of power into circuits not designed for it.

You need a "Speaker Level to Line Level" adapter which I believe is available from Radio Shack.

But ... you are really hooking things up wrong.

You need a Dolby Digital AV receiver that has a LFE/Subwoofer output. Inside the receiver, it routes the low frequencies to this output.

If you use speaker wires - it contains a lot more signals than the sub is expecting to handle, and you usually need to send the subwoofer OUTPUT to the L/R or Center speaker.

You will be loosing all the other sounds using speaker wires.

It would help if you listed your equipment.
