My car has a standard double din headunit and 6 speaker setup. Its not bose, its brandes with supersound. I replaced it with a cd player, but the sound quality was not very good at all. At the moment, I have both hooked up and switch it between the two. The Stock tapedeck/radio sounds great and its also got the 7 pin plug to beable to add a stacker. I dont want to do this, I want find out if I can my pioneer cd player into this plug somehow and get the sound running through the stock unit so sound quality is regained. Thanks!
