Head unit turns on, I got power to the amp but the amp it self is not turning on, I don not have the speaker wire plugged in to the amp,but power and ground,it does have a remote lead from the amp,what I read in the 3 manuals that I have for subaru harness,head unit and amp there is a blue and white wire for head unit to harness,what I read from them manuals this should be with the remote wire goes,but it doesn't look like it.....been on this for 2 days now,

Alpine pdx-v9 amp
Pioneer avh-x3500bhs

Also the head unit need to have the parking brake wired....why and where should I connect this?

Head unit wire info

Yellow 12v constant
Orange/white lighting switch terminal( no wire on new subaru harness)
Red ignition switch(12vdc)
Black ground
Violet/white-reverse gear( what wire is this on the subaru)
Yellow/black- auto lead mute function( read that we don't have this)
Light green-parking brake(why?)
Blue/white-system control terminal of the power amp or auto-antenna relay

After that is the speaker wire that I don't think i use because I am using RCA cables

So if anyone is awake right now please help me will check this every few minutes

I'm not trying to be offensive but it might be time to get some local professionals involved. If the amp isn't turning on and you've got 12v from the battery in the positive terminal, ground to ground and the blue/white to the remote lead of the amp. I havne't installed a newer Pioneer in a few years but the parking brake should go to the wiring for the parking brake so that the radio will limit some functions when the parking break isn't on. If I were you I would've gotten the harness from David, svxDc and you can check his site for some additional wiring information.
