I hooked up my delphi xm radio to two different stereos in my home.. 1.an all onkyo system which buzzed terribly and did not go loud, but I replaced the mini to rca and it got much better, and 2. a bose system which had the same problem, but when I replaced the chord THE BUZZING DID NOT GO AWAY, even though it did on the onkyo (and dont say it's the bose, cause I know it sucks but not that bad!) My question is if anyone else has had this problem and what did they did to fix it. Will buying monster cable mini to rca chords fix the problem. I also hate the fact that the music comes in so much lower then cd's and even normal radio. I have to crank both sytems up to hear the music.
