Seemed alright at the beginning
Crutchfield Customer Review (What's this?)
I bought the PIE version of the adapter because Crutchfield was out of stock of the Alpine cable. It seemed fine to start with, but eventually the sound started to cut out on the right side of the car. I tracked it down to a cable problem, replaced the cheap RCA cables I had been using, all was well and it came back. Turns out the PIE cable's plug doesn't fit as snug, and the pressure of the RCA cables was pulling the plug a bit out. For basically the same price the Alpine cable is original equipment, the plug fits better, and the RCA ends of it have insulation around it to keep your cables from grounding to other metal in the car. Buy the Alpine cable.
