I recently bought this adapter for work to connect my sirius Starmate 4 radio into the radio at work so everyone could enjoy satalite radio. After about 2 hours trying to get it work (I didn't have a wire in all the way) I got it to work and everyone came up to me asking what they were listening to. I must of got like 3-4 people to signup for sirius radio the first night I had it hooked up. The sound quality is supberb, the bass is kicking. This adapter is a must buy if you want to enjoy sirius radio in the house or in my terms at work.
