Ck to How can I hook up a home subwoofer with an L/R jack to a Pre-out(RCA) jack on the reciever?

Question

The subwoofer does not supply its own power. Are there converters from the old L/R system to RCA jacks which would also carry power?

If I cannot how much should a subwoofer cost me?

Answer 1

if the subwoofer is not powered than you cannot hook it up to a pre out, because a pre out is not powered, and is meant for use with a powered subwoofer, you need to connect the subwoofer to the powered subwoofer output on the reciever, it is probably a speaker wire output
