EDITED!

Im looking to add a 5 channel amp to my stock head unit.
with those 4 channels i'm going to use its for front and rear
and then a subwoofer.

You'll need a line out converter. I'm assuming you're swapping out your stock speakers? If not, I can't see a reason to amp them.

Adding the sub will need the LOC. I used an LC2i from AudioControl since I was just adding the sub and not changing up anything with the stock speakers for the time being.
