Okay so my 2000 dodge ram slt has reealy bad hail damage. today I got a new extended cab door in. easy.... But I guess the donor pickup had infinity sound system and I didnt.... on my bigger Driver side door there are only 2 wires but on the new one it has like 20 wires just to a speaker....if I dont switch my speakers will the infinity ones work? Even if I didnt have that package? It has a black block type thing on the back of the speaker.... If I wanted my normal speakers how would I wire them? I just got new speakers

 

Just transfer everything from your original door, to the new door. Including the harness.

 

Just cut all wires and run your own, that black box thing is the infinity sound amplifier which are known for going out, just do a search and youll find a thread about how to do all of this
