Of Course he lost his sync that is part of the Stock headunit.

Remove the panel surrounding the headunit and the air controls/vents. Its all clipped in so just tug on it. Then remove the 4 bolts and pull headunit out. Run the RCA's on the right side of the vehicle to your trunk. I dont know what your going to do about a remote wire unless but that is a entirely different issue someone else might be able to explain to you.

But doesnt this put the Total resistance on that channel @ 2 ohms which pretty much all headunits cant support so it would end up damaging your HU because its internal amp will run too hot and the sound not be clean?

I have already installed my HU and the speakers. I bought wiring harnesses to make it alot easier. I was wondering because my speakers sound good but I want to hook up the stock tweeters because I want some ear level tweets without buying new ones. I am not using a amp and I noticed on the stock speakers there are bass blockers ( I have a pair of 8400 mF bass blockers) and that it appears the speakers & tweeters are wired in parallel. I dont think the stock HU is capable of producing a 2 ohm load so this seems odd to me. So my question is if hooking up the stock tweeters in the same way that Ford has them is a good idea on my new headunit which the internal amp is only rated for 4 ohms. I am asking this because it only appears to me ( not a expert) they are run in parallel unless someone can confirm they are run in a series. I would like to run my tweets right from the headunit but its only 4 channels Any suggestions or answers to my questions?
