Sorry for the long post as well it's a lot to read :yes:
Okay so to start of this is my first time ever installing something like this in a car, I followed the instructions that come with the kit however when I fitted my new active subwoofer in my car I thought all had gone well it turned on and played music through it, however the subwoofer does not turn off when I remove the key from the car.

I have googled this and it said something about the remote turn on wire which for me is on the back of the head unit and is a blue and white wire. The cable that come with the subwoofer is blue not that it matters as its a remote turn on wire for the sub but I ran this wire through the car to the head unit and then I have wired the blue wire with the kit to the remote wire on the back of the head unit which was the blue and white one.....I did this by simply cutting the wire in half and then joining them together with the blue wire from the subwoofer creating a "T" junction effect. I have not got a photo of this part however in the images you can see that I have had to tape up the blue and white again while I try and find a solution haha
Note:I had wired this all up before turning the sub on for the first time I didn't add the remote wire after.

Sorry for the amount of detail but really not sure on what the problem could be I can have links to photos if it helps as well.

Thanks to anyone who can help me smile.png

Active subwoofer: Edge EDB12A 2014 model

Car: VW Lupo W reg (2000)

Head unit: jvc kw-xr811 http://www.manualslib.com/manual/488544/Jvc-Kw-Xr811.html?page=2#manual (Wiring/ install manual for help.)

Okay so I had a second look today at this issue and I was thinking if it was possible to wire it in with the yellow wire from the iso harness as this gets 12v when the ignition is on and then goes off when the key is removed? If this is even right? this is what I mean: https://i.imgur.com/nBpyd5q.jpg

I have some photos to show how the ISO harness is done I had to change the yellow and the red wires around as the Unit was not remembering anything when I turned the car off so that's why.
When I first tried this by linking it up with the yellow 12v wire it made the car ignition go backwards the stereo would only come on once the car had gone from ignition to off it would not come on otherwise even if the car was started so not sure on that.
I also am not sure how to show images so I have had to post links to them as well https://imgur.com/a/N8lss

Two things

Are you using an aftermarket loom? Or are you tapping into the OEM wiring loom? I wouldn't tap into the the OEM loom. Grab yourself a cheap aftermarket loom off eBay, for one, the colours are usually standardized, two you can hack it up without having to worry about expensive repairs.

If you have an aftermarket loom, Red is live, Yellow is switched, Blue is remote + 12v antenna, you can splice it, hence the bullet connector below:

Hi thanks for getting back to me thought I would never hear from someone with this issue :)

I am using a ISO lead that come with the after market stereo I have not touched the main wiring from the car loom at all as like you said I do not want any big issues or big bills aha. I have only had this car a few weeks now and the person who had it before never bothered to change the red and yellow around as they never used the Head unit.

As you can see from this photo http://i.imgur.com/NiOqDyw.jpg I have had to do the red and yellow wire switch so that the unit would remember the settings. The tape over the blue and white is because I cut this in half the first time to wire in the remote wire from the sub as this in the Manuel for the unit says this is the one however it didn't work.

And also when I put the remote wire into the yellow like on the photo http://i.imgur.com/NiOqDyw.jpgit did turn the subwoofer on and off but it then the stereo would only come on when the car had been turned on then off for some reason so back to square one :(

I do not have just a solid blue wire from this after market loom only blue and white and as it says here it's for http://www.manualslib.com/manual/488544/Jvc-Kw-Xr811.html?page=2#manual"Remote lead/power aerial, 200 mA max. (Blue, white stripe)"

The connection point on the left side of the photo is not the same as on my unit it only has one connection that end and this one has two

So your unit isn't a standardized ISO socket?

Not that I think so as this is the end that goes in the unit http://i.imgur.com/vEe3gaD.jpgThis is not the same as the cable you have shown so I am guessing it's something to do with it been JVC double unit maybe I'm not sure sorry

On both the aftermarket units I've had the connector has been like that as well...

Do you have a multimeter? Could look at if the remote wire is constantly supplying power for some reason even when ignition is off?
