I'm looking to install an after market system in my 96 Explorer. It has the cd changer in the center console and the amp in the rear. No sub.

What is needed to run the new radio? Will I just need to fun new speaker wires to the doors?

Thanks in advance for your help.

 

So you want to bypass the factory amp? You say Aftermrket system, what does that consiste of? just the Head Unit? or also aftermarket amps?
