High Quality RCA. I needed a 1 Male to 2 Female RCA Y adapter, and me not reading correctly ordered this. However - I managed to make this work at my AMP instead of the head unit. Great sound quality, Cable is a good gauge and matches my RCA's already ran in the car. Connects easy and had this installed within minutes. Thanks Skar!
