2006 Explorer Stereo replacement

[cmk0808]

Replacing a factory nav unit on a 2006 Explorer with the audiophile sub and amp. Used a Metro 70-5521 harness. Noticed now that there is full range audio coming through the sub. The original factory nav unit does not do this. Anybody run into this or have info on how the amp works with processing signals?

You got a sub option in the settings on your replacement HU for the preouts?

On my JVC HU, the subwoofer had to be connected with a pre-out on the back of the unit. The wiring harness only had a wire to turn the remote amp on - not to pass the signal. Of course, I don't have a subwoofer so it's a moot point but that is how the wiring was.

here's what i now because im replacing mine if its an aftermarket head unit as what im doing
you have to grab a 12v to 5v step down. and have the 70-5522. red wire goes to the
car harness white blue from radio goes to the step down and ground to ground. i do beleave from all that
i read the only rca impute you use is the white one. calling Crutchfield helps allot
