I bought a radio from clutchfield.. Came with the by pass kit for the factory amp.
by passing the amp took the longest as a lot of interior panels need to be lifted up or taken off..
the radio came with a adapter connector that saved me from cutting any wires.
The radio has blue tooth and all kinds of ways to play music. Has flash drive, cd, SD memory card and blue tooth.. And it cuts the radio when a call comes in. even has a remote but dont see a use in it since everyt hing is right there.
sound is GREAT... daughter loves it..
the explorer is a 97 loaded limited awd 5.0 with 75k miles on it now since she been driving a lot in it,.. still has the factory firestone replacement tires on it...
wish it got better gas mileage. but the engine purrs and pulls strong..
