Why does my AV receiver have an RCA input for my subwoofer when my subwoofer uses speaker wire? (Part 1)

Episode 883 (1:39:31)

Paul from Los Angeles, CA

The receiver is likely assuming that Paul would be using a powered subwoofer. He'll need to buy an amplifier that will power the subwoofer. The power requirements of his sub will determine which amp he should buy. But Leo thinks the better option is to get a better, powered subwoofer. Emotiva has a sale going on right now and that would probably be a better way to go.
