I have the 6 disc cd player and i am trying to take it out I have been searching a long time and cant find anything. Also can i connect an amp straight up to this stereo or would it be best to buy a new one?

 

really the amp doesn't hook up to the radio the radio hooks up to the amp then from the amp to the sub or speakers. what do you want to hook up to the amp the sub or the mids?

 

I am hookin up 2 12" subs

 

then you need a one channel amp that will receive the signal from the head unit and a capacitor to put between the battery and the power for the amp the subs hook up to the amp normally the manufacture of the subs will recommend what gauge wire to use to the subs and the amp manufacturer will recommend something to get the power to it. the back of the head unit should have a red and a white plug this is the signal output that your going to send to the amp.
