What do i need to install this? Anything? I'm going for the amber look..... also can i have a amp/subs.. with a stock cd player? Thanks!

 

I'm not sure what you are talking about in the first part of your post, but yes you can install amps/subs with the stock head unit. You just need the convertor that converts the rca cables coming out of the amp to speaker wires which you twist with the back left and back right speakers wires going into your head unit. So the flow of audio signal to the amp/sub looks like this...

Head Unit -> Back L/R speaker wire -> converter -> rca cables -> amp -> subs
