I used this to connect a subwoofer and a processor. It provides sufficient bass and is definitely better than the free RCA cable that came with the subwoofer. OFC 2.0m black RCA audio cable, providing high-quality sound. - Brand: Purchased from Amazon - Model: RCA audio cable - Length: 2.0m - Type: 2 RCA male to 2 RCA male - Color: Black Shipping included, so I think you can buy it at a low price. Thank you for looking.
