Aftermarket stereo?

[AudiNike12]

How does that work in our Audi's? Mainly thinking about the sound. There's only wires for RR, RL, FR and FL speakers in the one I've purchased. There's a connector with all the wires that came with the stereo. It's one of those Single DIN stereos with a flip out screen. With GPS, BT etc.

I had to buy a harness that cost about 200$ , check your local stereo place.

I would try Crutchfield. They are pretty knowledgeable and have wiring diagrams and harnesses.

I don't even know what harness I should have or how it should look like. Here's a pic of the harness that came wth the stereo:



And this is the output on the stereo:



Would this harness help anything(PC9-401): http://www.pmshopen.se/a6-19941997-c...ds-pc9401-p-98

I've the 1/2 amp rear, none BOSE. Are the wires from the rear speakers wired to the amp? Can't I just wire them directly into the headunit or how does it work?

Another pic of the output:

[Terry.Reese]

you need to go to your local car stereo place and tell them you need a harness for the specific car you have, the stereo one will then hook into the other wiring harness for the car.

[AudiNike12]

So I ordered a PC9-404 since I've pre-outs on my new stereo. Gonna try and see if it works. It's for A6 2004 with half amp system

Here is what Enfig told me when I asked about my 2004 allroad and a Kenwood DMX7704S. I ended up getting the Axxess AX-AU12-SWC kit on Amazon. It works pretty well and retained steering wheel controls. I still am chasing some ignition whine though.

Wiring harness - Connects to your cars original harness and terminates into Blaupunkt style connector. (We also have PNP adapters that convert the Blaupunkt style connector into radio specific connections)

http://enfigcarstereo.com/ENFIG_SRWH_AUD2_HILO.html Fixes low rear audio and does steering wheel controls with a SWCL.

http://enfigcarstereo.com/ENFIG_SRWH_AU2.html This DOES NOT FIX audio issues but is cheaper.

We were going to make a no steering wheel control HILO but decided to bring the price of the HILO with steering down to the no steering price.

We did the same with the non HILO units and got rid of the SRWH-AUD2-NS. Its still on the site but if you order it we just send you the SRWH-AUD2-B



Adds steering wheel controls to the boxes above.

http://enfigcarstereo.com/ENFIG_SWCL_KEN.html



Converts the Blaupunkt style connection into a connection specific to your radio.

I can make this PNP for $50 and refund you $20 when you send in the one that comes with your radio.



Antenna adapter - This converts your 2 antenna connections into the universal connections most radios need.

This is out dash kit. It matches the factory dash pretty close to perfect. We do not have a cheap kit for this because they all look bad in our opinion.

Keys to take out the radio.

To use factory Satellite antenna you must run the cable to the tuner in the trunk. You will still need to buy a new tuner this is just to use the antenna.

http://enfigcarstereo.com/ENFIG_SAA_SIR_600_GREEN.html





To use factory GPS antenna. I think your car has it in the back left but I’m not 100% sure if it even has one.

http://enfigcarstereo.com/ENFIG_GAA_3.html

If car has GPS antenna on roof but not behind radio you will also need this extension.

I went with the enfig kit as well (HiLo and steering wheel controls), expensive and a pain in the ass to jam the giant bundle of wiring behind the radio but I didn't want to spend time fiddling with piecing it together myself, and when I priced out all the individual components I'd be saving like 20 bucks at most. Also found out that you need to snip a wire at the headlight switch if your car has DRLs and you want the illumination to work properly, that wasn't documented anywhere.

I had that as well, I went and got some line filters and boom all gone.

[AudiNike12]

What kind of antenna adapter do I need for these 2 cables:



Here's the antenna connection on the new one:



Is it this one: https://enfigcarstereo.com/ENFIG_AAA_VWAUD2.html

From what I can see, that adapter is the same as these 2 pieced together:

[jbain2]

The one from enfig will work but its powered so you’ll need to tap a switched power source.

Ok, how do I do that? I don't know much about this so I need all the help I can get 😔

[Mad Cow]

I think the enfig harness has an empty spot for the wire in one of the connectors, you just pop it in. Or you might have to remove a wire and pop that one in it's place, either way it's very easy to do. If you want fully plug and play they can make the entire harness for you, including the radio side connections.

[AudiNike12]

Are you talking about the blue wire on the enfig adapter? Or where should that go? I bought the PC9-404 harness and there is a blue/white wire there. Should they both go to the blue antenna wire from the HU?

PC9-404 harness:



Can I just use something like this to connect 2 wires into 1:

[Mad Cow]

I forget exactly where it goes, but there should be some documentation in their site or printed on paper with the harness that explains it. I'm not a fan of terminal blocks like that, better to crimp or solder if you have to.

[AudiNike12]

Thanks :)

So the wires from the headunit(left in first pic). What kind of connection do they need to have to fit inside the black plug etc. I assume they go straight in there with some type of connector? A bullet connector? A pic would be nice

[Mad Cow]

This is where you bust out the soldering iron or crimpers. Good chance to de-pin all the unconnected wires at the head unit side too, you only need like a dozen.

[chris86vw]

Yup crimp..

Crimp caps work best behind a radio vs normal butt connectors any auto parts store carries them at this point. Usually clear and look like a twist nut you'd use in house electric but a crimp

[AudiNike12]

I've read there isn't a swiched live(ignition) on my car? Is that true? What do I do then?

Edit: Have installed the new stereo and connected everything. Everything works except it doesn't turn on/off with the ignition. Have to manually turn it on/off. Guess I've to feed it from a fuse in the fuse panel on the left or something. No biggie though. A shitload of wires behind the stereo though. Not too happy about that

[AudiNike12]

Btw. thanks for all the help. Much appreciated

[chris86vw]

75x terminal under the dash is switched. Or there is a wire off the cluster, blanking right now which, that will keep it hot while the keys still in.

[AudiNike12]

Thanks. I'll try the 75x terminal It's below relay 1 right?

[chris86vw]

Thanks. I'll try the 75x terminal It's below relay 1 right?

Its labeled but will have the black and yellow wires going to it (and probably labeled in black and yelllow).

Closest one to the hood latch. the rest will be 30 30 30 all read wires constant 12V/hot and the final one near the pedals will be 87F diesel (which is a prime with door switch and then works as key on power.. so could work but don't want that one)

[AudiNike12]

Hello again. The stereo doesn't remember the settings, stored radio channels etc. When I turn on the stereo it's all cleared. Anyone know what to do? Is there a wire for this?

Haven't done the 75x terminal yet

[sailor83]

The radio is supplied with a +12V(always have +12V) , and an ignition +12V.

It sounds like you are missing the +12V and only have the ignition +12V supply connected. (or they are switched, on my pioneer they where switched)

Iso - plug in the car? right? read this then: https://en.wikipedia.org/wiki/Connectors_for_car_audio

[AudiNike12]

At the moment, both the +12V(yellow) and the ignition wire(red) from the stereo is connected to the +12V(red/yellow, don't know if this is both +12V and ignition) in the harness from the car.

Maybe the yellow wire isn't properly seated in the crimp connector so it only gets power to the red wire? Or is the yellow/red wire from the car not +12V?

[glennda5id]

There is no siwtch ignition if my memory serves me. When the ignition is turned on the CANBUS starts talking and things turn on. The point of the ENFIG adapter or similar is to pickup that canbus messages and then supply the +12 ign voltage to the radio.

Most modern cars are like this today and you need a canbus adapter to make it all work.

You can still find a switched source and tap into it, the radio won't draw any real power through that wire since it's just an on off signal. Problem with that is you can't turn just the radio on since the ignition switch doesn't have an accessory position. I worked around that in my old b5 by installing a 3 position rocker switch inline with the radio's switched wire so that I can switch between switched and constant 12v. I used a canbus adapter in my c5 which keeps the radio on until I pull the key out when going from on to off with the ignition switch, it's a great feature and well worth the extra 50 bucks or whatever the adapter costs.

[rollerton]

The signal you're looking for which is keyed ignition 12V and stays live until the key is removed is found in the big BLUE plug at the back of the cluster and is a very tiny thin red wire. (pretty sure if memory serves). I've used it as 12V signal on several stereo installs. Verify which wire you're using though with a voltmeter (or test light). That same circuit is found in a few places in the front; also at the sunroof harness if you want to install a radar detector. I actually have a pic saved somewhere of which wire it is exactly..have to find it.

[AudiNike12]

Thanks for the answers. I'll take a look at it this weekend if I've the time

[AudiNike12]

Another question. How come the stereo keeps playing after I turn off the car but I can't turn on the stereo until I start the car? I know I've probably wired it wrong but still

[chris86vw]

The key still in power is only a retain power until key is removed power source. It doesnt turn any power on simply by inserting the key so you need to turn key to on position then that key in power is triggered and remains until key removed.

[AudiNike12]

Ok. But it keeps playing after I remove the key By that logic, shouldn't I be able to turn on the stereo without a key since it keeps playing without it?

[chris86vw]

Oh sorry I thought you had rewired it now to work with the key in seitch for power.

You have the red wire and the yellow wire for the new radio going to the same wire still? That red/yellow you mentioned before or something else?

[AudiNike12]

Yes, red and yellow still going to the same wire. Maybe that's the problem? Could that also cause the radio losing its settings? Haven't had the time to rewire it yet. Hopefully between Christamas and New Year

So is the 75x terminal and the red wire in the blue plug both "live until key is removed" or is it only the blue plug?

[chris86vw]

Yes, red and yellow still going to the same wire. Maybe that's the problem? Could that also cause the radio losing its settings? Haven't had the time to rewire it yet. Hopefully between Christamas and New Year

If it is losing power when the key is off/out then yes it would lose its settings.

On a car stereo (aftermarket) yellow will be constant hot and red will be switched, so if the yellow (paired with the red) is on some sort of switched source then you will lose power once ignition is off, why it is staying on after the car is off and not coming on when the car is off (if you switch it on I 'don't know)

So you need to wire the yellow aftermarket radio wire to a constant 12v power supply, the stock radio one should work for this. Likely a red with a white stripe wire.

For the red wire from the aftermarket radio you either need to wire it to the one in the blue connector mentioned by rollerton or or the 75x terminals under the dash to be switched with ignition (75x) or switched with ignition but stays on with the key still in you'd use the one from the blue cluster connector.

[AudiNike12]

Thanks for the help. It's much appreciated. Where do I tap into the red wire in the blue plug the easiest? Right at the blue plug behind the cluster or somewhere else?

[AudiNike12]

I've now rewired it and used the 75x terminal. It now turns on/off with the ignition and it remembers the setting. Thanks for all the help
