Therefore I need to use the OEM harness for the head unit to bring the amplified signal from the new head unit to the front of the car and then connect those wires to the speaker runs to the back of the car, right?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Spent 9 hours on sunday installing the following into my 2000 C4 coupe with HIFI option:
Alpine 9855 + iPod thinggie
Focal 100CV
Focal 5WS
Audison SRx5
Things are pretty much hooked up and working except I still need to:
Mount the crossovers for hte 100CV's properly
Mount the amp (still knocking around in the front)
Hook up remote power on
Hook up rear speakers to the head unit
So I have some questions:
1) I hooked up the remote turn on wire from the head unit to the right color on the harness that hooks to the OEM harness... but I haven't a clue where the wire comes out in the hood area of the car!? The wire appears to be Yellow/Black in the harness but there's no yellow black up front! I looked around for power when the ignition was on but couldn't find any with my multimeter... anyone know the secret?
2) I am getting really poor sound out of the 5WS in the door. I purchased them used from an authorized dealer who said he installed them in a car and then the owner wanted something bigger. He gave them to me really cheap and they were in the original boxes. He said they were not the current model... the weird thing is that they don't say 5WS on them and they don't look like the pictures I've seen on the internet. I think I did a good job sealing the speaker into the enclosure and I've screwed around with the amp settings... but they keep distorting at fairly low volume and they don't seem to produce good bass. Any ideas?
3) The radio reception is very poor. I purchased the adaptor and hooked it up but the male part of the adaptor doesn't really fit well and some of the metal is exposed (I know I need to take a picture of it)... are there any tricks for getting it to work better?
4) I want to hook the existing rear speakers into the head unit. I believe that they were previously powered by the amp in the front of the car. Therefore I need to use the OEM harness for the head unit to bring the amplified signal from the new head unit to the front of the car and then connect those wires to the speaker runs to the back of the car, right? Does anyone know which color speaker cables are the rear speakers on the harness at the front of the car?
Thanks! I'll be sure to post some pictures soon!
