just purchased a 04 xfire with infinity system replaced rear subs and added flip out unit . had best buy install head unit when i got it back sounded amazing but as i took off the spoiler popped up, odd because i have it set down and the red light was blinking . spoiler now will only go down when key is on acc. soon as car is started i get the spoiler popping up ? the " pro installer" cant figure it out he used a scosche harness for merc's . should he be using a different harness or is he missing something obvious some of you have come across ? any help would be appreciated from a newbie

 

First thing you must rule out is that your battery is going bad. Once confirmed you have a good battery, then proceed to other diagnoses. Have your battery tested by known-good shop.

Low system voltage will cause the spoiler to deploy on its own. You may be dropping below the voltage threshold when cranking.

Battery is fine been tested noticed that if the door lock from key fob is pressed head unit loses memory radio is powered off wondering if it's something crossed in the harness

 

Still betting it's the battery or connections!

 

Did problems start after radio install. Possible your head unit is not wired correctly.

 

Scosche VW01B, this is the harness that I used. I haven't had any problems. I know it says its for a VW but it fits our cars too.

 

To answer all questions yes problem started after install of New head unit will have battery re tested . Headed. Back to best buy today will bring up new harness see what happens. I also appreciate all the help. Support specially for a newbie you guys are awesome.

 

Forgot to add this earlier, I went to best buy when I was switching to an after market radio. They didn't have it, I think I got it at walmart, you might want to call around before you head to best buy.

 

What happens when you unplug the radio?

 

180 beat me to it.
The old Biblical "If the eye offends thee, pluck it out" strategy.......

 

^^^ correct.... if you make a change and things dont work right after, undo the change and see if things work normally again...

 

Actually on it right now pulling new unit out and looking to see if any wires are backwards from there it's putting stock unit back in to see if problem persists or just a freak occurrence I will keep u guys posted. Thanks again for all the help along the way

 

On the other side of the factory harness does anyone know what wire controls the spoiler and does it need ground etc I'm here now so a quick reply would be greatly appriciated

 

Just leave the deck unplugged completely and start the car. You dont need to put the stocker back in to test the theory.

 

By putting factory head unit back in everything works like it should btw

 

Well then I personally would tripple check that the wires are met properly. Power to Power, Ground to Ground, FL to FL etc.

 

Swapping red yellow to yellow red noticed that was off but as far as I can tell that's just for memory but gonna give it a shot

 

What harness did you end up getting? How are the wires from the back of the deck met with the wires of the harness? Crimp connectors?

 

Volks harness the one suggested all colors match except blue white to blue and red yellow to yellow red I'm just clueless so is the installer

 

What is the factory color wire supposed to be connected to the two blue wires added in
