I have a powered subwoofer. How do I connect TWO RG6 M-type connection to it, using one RCA M-M cable?

Answer 1

Your sub has a right and left input correct?

You will not need to connect both as these are signal level inputs to come from a stereo receiver or amp to reproduce L and R bass frequencies. It all gets combined and attenuated in the sub which does not have two drivers but one.

Usually the owners manual will tell you to just connect to either or specifically the left channel. Your surround receiver will have already mixed for the LFE channel.

If your signal is comming from a LFE source and not a special application you will be fine with the above set up. If it isn't a home theater application you need to provide more detail about what you intend to do.

Answer 2

So you have 1 cable from the receiver and want to fill both RCA Female jacks on the sub?

You can get a "Y" adapter from Radio Shack that splits the end of the M-M cable into 2 Male plugs so you can fill both female jacks on the sub.

Or do you have 2 sources of LFE, but 1 input jack on the sub?

Radio shack also has the reverse "Y" adapter with 2 female inputs and 1 male output. But I strongly suggest you dont do this. You dont want 2 output devices to be plugged into the sub at the same time. Buy a inexpensive A/B switch so you can toggle between sources.

Answer 3

In your situation, you will need a physical splitter cable, that goes from female-RCA-to-dual-male-RCA outputs to connect to your subwoofer. Due to the nature of subwoofer frequencies, there is often no need to seperate L and R channels, so many devices carry only one RCA to the subwoofer. There is no loss in audio fidelity with this adapter, assuming the quality of the adapter is adequate.
