RCA Cables (Low-Level Connection): Most common for powered subwoofers, these are single or dual RCA cables that connect to the line-level (LFE or sub out) output on the amplifier or AV receiver and the line-level input on the subwoofer. Dual RCA cables are often used for stereo inputs, but for a subwoofer, a single RCA cable is usually sufficient because low-frequency effects (LFE) are mono.
