I have a Sony STR-DE597 FM/AM Receiver .It has audio out plug and i have a Jensen js650 100 watt Subwoofer. how can i hook them up. Thanks.
The reason you may find it difficult to connect the Sony Receiver to the Jensen JS650 is that the JS650 does not have a line level input (RCA) to match the RCA subwoofer output of the STR-DE597 receiver. In this case, all you need to do is connect an extra set of speaker wires from the "Speaker B" Left and Right speaker connections on the back of the Sony to the speaker input connectors on the Jensen. On the front panel of the Sony, select speakers A+B settings so that the subwoofer is on in parallel with the front speakers.
I hope this answer is helpful to your home system set up.
