Radio not turning off

[Wrighty_1988]

Hey ive got a 1989 mk2 golf gti.

When i turn the car off and pull the key out the radio is still playing and also my amp is still on even though the remote wire is correctly wired up ?

Any idea's will be most welcome

I dont think that any of the MK2's had a ignition live which means your radio is live even when the ignition is off and the amp will stay on as long as the head unit does

hum, how does everyone with a mk2 golf who has a sub in it get around this problem?
Thanks

I had a sub in my previous Golf and the stereo in that was wired to a perminent live ? What do you mean when you say get around this problem ? When the radio goes off so does the sub !

You can splice into one of the live lines for something else behind the dash.  This will be a switched 12v, i.e. only on when ignition is on.  Your head unit will have a "switched" 12 v input and a continuous 12v input (to keep stored channels etc), so at the moment you will find that the "switched" 12v input is probably connected up to the continuous 12v.  If you do splice into a switched 12v, the head unit will switch off when you turn the ignition off.  However, it means if you want to listen to the radio, you always have to have the ignition fully on (as there is no "accessories" position at the ignition switch on the Mk2)  This means your fuel pump and your idle control valve will be buzzing away while you're listening to  the radio.  I did this for a while but have since converted back.  Dont know if its good to have the idle valve buzzing away with nothing flowing through it.

Ah, the wire that i have the amp wired upto at the moment is the ACC wire which i think is red, could you suggest another wire behing there i could wire up to ?

If you dont have a "remote on" wire you could use the electric aerial wire if your radio has one ?

Hum, will have to have a look, got a fairly good head unit and i can remember there being a few wires comming out the back of it that went nowhere. Thanks alot for your help

No probs dude

one of those wires will be for an automatic antenna
Regarding a switched 12 v, I cant remember what I used, it was maybe a wire leading to the fan control switch.  either way, u can figure it out with a voltmeter, see if you get 12v with ign on, that goes to 0v with ign off.  I think i used a wire for teh fan control;It worked fine for mine because I didn't have amps...you will need to be careful what load you're going to put through it.
