To connect a subwoofer to a receiver, you will need a subwoofer cable. A subwoofer cable is a type of audio cable that is designed specifically for low-frequency signals and is used to connect the subwoofer output on the receiver to the input on the subwoofer.
Subwoofer cables typically have a single RCA connector on each end,
which is used to plug into the subwoofer output on the receiver and the input on the subwoofer.The cable is usually shielded to minimize interference and signal loss and is available in various lengths to accommodate different setups.
When choosing a subwoofer cable,
it 's important to select one that is of high quality and has good shielding to minimize the risk of signal degradation or noise. The length of the cable should also be appropriate for your setup, with the shortest cable possible that can still reach the desired connection points being the best option.
