Ohhh kay, i want to replace my cd player i have the cd player and everything but i have a question, how can i wire it up to my factory amp and sub in the back i dont want to go without them... if u have aftermarket cd player with the rockford fosgate upgrade on ur spec v , do u have the amp and the sub hooked up? How did u do it? Where did u get it done if it was professional? and how much?

 

No1?!

 

I have heard that it is difficult to hook up aftermarket head units to the rf sub and amp. If I remember right most people replace their stock stuff rather than try and make it work. Id try the audio section of thevboard since theres probably not anyone here thats gone through your problem. The audio forum here might help too. Good luck.
