How to install sub, amp, cd player in 2000 ford taurus?

• i seen the link and i have that in the trunk ,problem is im trying to install a new stereo in the car as well as a sub-amp for sub. the wires from the old cd player have differnt colors then the new stereo i hooked up the radio with differnt combanation to c if the radio would work but nothing no sounds ..cd player has power but no sound. my question is how do i get sound do i have to tack that amp out? or put new wiring in for the speakers.? thank you hope to hear from you

• Answer:

  well lets see here ! so ur confuse on which wire colors go to what speaker right? did u think about buying a wiring harness for ur new after market stereo that would solve the problem,and if u don't have the budget for that u could always undo the door panels and check the speaker wiring for yourself to see What color is what.
