93 changing bose stereo questions

i am wanting to change my factory bose out. i have a 93 rx7 it has the cd and tape stacked with the bose in the back. my question is i am gonna take out the acoustic thing in the back and put subs and amp. now do i have to change door speakers or will they hook right up to a new c.d. player? they sound good if i could use them that would save some money. if i have to replace them then what size are they? and do i have to run new wires thru the door or can i use the factory wires

take off the panels and check

i know just wondering if anyone put in a new cd player and used the factory door speakers

its all the same, new ones would just be louder/sound better if you bought nicer ones, but if the ones you have now are bose then they probably sound good already
