My mistake, its two thick and one thin.

I can only think that you have the thick wires the wrong way round maybe? Did you trace one all the way to the Sub?

Yes, well as far as I could. The only side I have doubt over is the drivers side, the splices were virtualy under the seat and I didn't have a torx bit big enough to remove the seat, passenger side i'm 99.99% sure that's correct which is why i'd of thought I'd have one side working.

It's got me stumped, the wiring is correct, the amp has power,

Any surggestions ?

I would start troubleshooting. You have one of the old mids you can use to test with. Unplug the connector at the amp, find what should be the feed from the head unit and see if you can test the feed with a spare bit of speaker cable and the old mid by loose connecting the spare bit of cable into the connector.

Test both left and right and check signal is going to the Amp. If it is, then looks like the amp could be at fault (as its unlikely that every output channel is incorrectly wired).

I fitted both mids and tweeter yesterday before I started the wiring, they worked fine so I think I can eliminate them

I would definitely check the feed to the amp at the amp itself then. If you have signal going into the amp, then it suggests the fault is with the amp itself.

[JonD]

Ok,

At the amp definitely have a input on one side but no output (struggling to check the other side, it’s dam painful hanging out the boot with a slipped disk in my back).

What I find strange is every now and then the amp light goes out and also very occasionally i’ll get a crackle through the front speakers.

[JonD]

Ahhhh all up and running now, had the input and out put wrong on the passenger side which was stopping the output from the amp, as soon as I disconneted the passanger side the drivers side came to life.

Cool

So, you happy with the sound? What are your thoughts?

[JonD]

Yes, I’m pretty please with it, there’s a lot more clarity to the sound, I reckon the subs could do with upgrading. I’ve seen on here a thread somewhere, a sub upgrade that doesn’t require any modifications the sub housing.

JonD, can you confirm which colour wires you have cut into on each side?

[JonD]

On each side of the car you will find two splices, each splice cotains three wires, first splice three blue/brown, second splice three blue/ black. Each splice will have two thin wires, these are the mids (door speakers). The two thicker wires, one pair will be for the head unit, the other pair for the subs, easiest way to identify a pair is trace a blue/brown & a blue/black to the sub. The remaing pair are for the head unit.

Glad to hear you sorted out the wiring JonD.

I had the same trouble as you identifying the wires at the splices and I described my method of identifying them in post 38...

Here is photo from this topic but with marked colors of the wires, hope it will help !

[Pagnobito]

As this is a sticky would you mind editing the very first post to include the wiring diagrams there please? I don't mind looking through threads but they are right down on page 10. Thanks!

[Busha]

No problem since this diagram is not mine originally. If the original poster agrees sure that admins can put it on page 1. But I cannot do that since I am not admin

Have you tried adjusting the PDC volume via the audio menu? I did that when I first got my car with the Alpine upgrade fitted as a dealer option - damages your hearing as audio system gos to max volume! Ask bmw to sort design fault and they will tell you there's nothing wrong!! Design fault on all models with PDC and voice activation system.

Anyone else got the same problem? Be careful!

Only three posts since joining, and all three say the same thing, but in three different threads!

I don't get your point either? The PDC beeps are loud when you turn the stereo up and the PDC volume up? Hmm, how about turning the volume down?

[sbce90]

hey im having some problems with my system. i recently had the alpine upgrade installed by bmw. but now when i listen to a bassy or full sounding piece of music at moderately high volumes, a clicking / tapping sound seems to be coming from the subs. I took the car back to bmw and they said there was some 'internal fault' with the drivers side sub and have ordered a new one under warranty. after playing around with the balance / fader , i believe that the clicking seems to come from both sides. im not entirely sure that new a new sub will fix the problem.

anyone got any ideas?

Where does this amp get it's on/off (ignition) signal from?

I know what you mean.I pulled up outside the in-laws and turned the volume right down and went to adjust the PDC volume and my music came on full board too.They must have thought who's this muppet?.I don't know a way round this unless you select AUX with no device connected and then try adjusting the PDC volume ,I haven't tried it myself yet.It's even louder with the Alpine upgrade aswell!.

The line-in feed from the speakers 'wake' the amp up. No seperate power control cable.
