Hello,
I've done plenty of searching and asking but I'm still confused about exactly what wiring adapters I will need when fitting my Alpine 9812RR Headunit into my MK5 Golf Gti.
I already have the VW fascia adapter, and I believe I can get either an expensive CAN BUS adapter or get a cheaper std adapter and wire a switched live feed to the fusebox or just not bother having the unit switching itself off. So which is best? Is it worth spending the money on the Can bus adapter? Oh I don't have steering wheel controls to worry about.
My biggest confusion is what aerial adapter I should be buying - do I need a double one, does it need to be powered?
Advice and some links to the products you have used would be much appreciated - thanks! :)
I've fitted loads of aftermarket stereos into my previous cars but never had this much messing. around!! :D
-
Well looky what I found! :wink:

Hoping this is the right stuff. :)
Still not sure if I should splash out for the CAN BUS adapter though..... :undecided:
Oh, but I would add DON'T buy the single din fascia adapter from that link! The VW one is much nicer and almost half the price!!! :shocked:

You have near enough makes no difference the same HU as me. I just run a standard adaptor as they wanted silly money for the CANBUS. I remove the front of the HU every time I get in and out the car and it auto turns itself on and off when put on / remove the unit so not much difference there. As for the ariel adaptor Im not too sure which one I bought, I went into a local Audio Specialist place and he gave me the adaptor I needed, if you go into any audio shop or maybe even Halfords and say you have a MK5 golf and want an ariel adaptor (id recommended one with a signal booster like mine) Im sure they will point you in the right direction. Its not a double one, I just used eni meni minei mo technic and choose one of the two at random to plug in and I seemed to have chosen the right one as my reception is aright.
Hope this helps.

Thanks AlanD,
I remember you posted about using an standard wiring adapter on my other thread - I was thinking that our Alpine head unit automatically presented the fascia as the power was switched off, but I think that may have been my last Pioneer HU! :undecided: My Alpine HU has been in the box for a couple of years.
I did read on one forum (which I can't find now) that there is an adapter for the aerial that uses both aerial connections - I'm wondering why there are 2? :huh:
I do like the idea of your advanced decision making using vorsprung durk eni meni minei mo technique ! :laugh:
-
Im not sure really why there are two either, maybe someone else on here knows what thats all about (TT seems to know everything). Iv not really looked into it anymore as mine is working with one lol :D. It does get a bit staticy sometimes which it never did with the original HU but other than its fine.
As said your best option (and fastest) would be to go into an Audio specialist and say right I have this this this and this and I want it in my MK5 Golf, what do I need, any place worth its salt will just say you need this this this and this (they will try and sell you the CANBUS as its more money but as said, you dont NEED it).
Its not as complicated as it first looks. The way I did mine was removed the original headunit, (there is a how to guide online) if you are going to do this yourself give me a PM and I can try and give you some pointers e.g try as hard as you can not to unplug the airbag sensor as it will require VAGCOM to reset it (found out the hard way lol). It was then a case of connecting the CANBUS to the £10 ISO adaptor and plug that into the HU, take the ariel and plugging that into the adaptor with the signal booster and then sticking that in the back and then wire the amp / sub into the back of the HU and hey presto.
Hope this makes sense lol
-
Can someone explain what this CANBUS thing is/does? I'm thinking of changing my RCD 300 for an Alpine HU and iPod lead. I'm a bit clueless. Thanks!!
-
The CANBUS system is the just a connection which links all the cables to the headunit. Using the CANBUS allows you to use all the extras that a modern cars has e.g auto dimming the HU when your light turn on / off, increasing the audio level as your speed increases etc. Using a standard ISO adaptor like I have only incorporates the critical audio cables required to run a different HU.
I have lost all these extra functions in bypassing the CANBUS system. When I did my audio install the guy wanted £110 for the adaptor. I found them for about £90 online at the time. Not sure if they have come down in price or not. Its a lot of money for what is effectively some plastic with a bit of metal and some cables.
-
Cheers Alan, that does make sense, what doesn't is that I'm sure when I last fitted the Alpine HU it had (as I think I mentioned in the other thread) a power lead that the instructions insisted should be attached directly to the battery - now I guess this is just a precaution for older cars with lower gauge wiring, but I'm sure this is separate to the main connector. Guess I'll have to just order the bits and see how I get on!
Thanks. :smiley:
-
I do remember you mentioning this in your other thread. There is NO need to attached the Alpine HU to the battery, no idea what your manual is going on about ( lol you actually read a manual :shocked: ). The HU gets its constant supply from either the CANBUS or the ISO adaptor (which ever one you decide to use).
-
i've just got a jvc kw avx810 fitted by a audio dealer, he fitted the iso adapter facia and eventually can bus ,, oh and the aerial thing.. the aerial core is 12v to the amp at the ae, this is why we neeh an adapet otherwise no amplified signal... anyway all in all it cost £183 qiud to get fitted inc parts.. i felt well ripped off thr stereo only cost 250 quid..
-
Last weekend i ripped out my crappy factory fit VW stereo and fitted an Alpine H/U with new 2 DIN cradle.
I had the same issue with cabling. I can concur with previous posts - all you need is an adapter plug and a booster for your radio.
If you require the Alpine to turn off when you remove the key out of the ignition then that will not work as this is connected to the ECU (so i was informed in when i bought the adapter) TBH I didnt see the point in opening the fuse box and working out what but you may.....
-
Also, if you do take your live via the fusebox you wont be able to turn on your headunit on unless the key is switched in the ignition.
When your in the car park with your hommies you wont be able to play your choones without leaving your car unattended init.
-
Yes I do read the frigging manual :laugh: - don't think you've got a hope in hells chance of getting into all the sub menus on an alpine without reading it!
IIRC - Supposedly the 9812R needs power from the battery as it's 60wpc and causes a large current drain.
Gonna go and fish out the manual and see! lol
-
Well mine ISNT connected to the battery and hasnt been for 6 months now running a sub and amp and have no problems. . . .

I'm not questioning that it won't run with out being directly connected to the battery, I just think I may have to mess around with the loom adapter as I'm sure the main live feed is separate? Am I making sense?
-
Yeah, I see what your saying but the main live feed isn't separate, its part of the CANBUS adaptor which will then be connected to your ISO adaptor. (its either a yellow or red cable, cant remember, if you have a multimeter is will all make sense lol)
-
Hi AlanD,
Hopefully you're still monitoring this thread.
I think I may be getting somewhere - is the adapter you bought plugged straight into the small multi-pin connector on the back of the Alpine, or does it connect onto the ISO connectors on the end of the wiring adapter that came with the Alpine?
I dragged the unit and the instructions out and the wiring adapter that came with my Alpine does present a separate yellow wire with bullet connector for connecting directly to the battery and a bullet connector for connecting to ground. There is also an ISO connector for the speakers and an ISO connector for dash illumination and switched power along with other trailing wires.
There is a great big f**k off yellow sticker on the yellow + wire demanding that you connect it directly to a battery due to high current drain!
So I'm thinking either you have a direct Alpine to MK5 golf wiring adapter, or they changed things on later 9812R models (I've had mine for quite some time!).
What da ya fink?
Cheers matey. :)
-
later 9812 alpines have the yellow(permanent 12v+supply) in the loom
the canbus generator does NOT give you the premanent 12v it gives the following connections only
ignition/switched live
rpm
speed pulse
illumination
reverse
handbrake
some canbus adapters will only give rpm and switch live
yes you can connect the switched live to the fuse box it will work fine
but be careful when doing so as depending on where you connect it you can cause a fault to come up on the clocks
but that is easy to get reset

Sir, you are a superstar! Thanks :smiley:
I've ordered my loom adapter and radio adapter now and will just splice them together as I have in the past on other cars - I'm not too worried about CANBUS and switched live as I will be taking the fascia off anyway.
Cheers. :)
-
have you also ordered the aerial adapter as that needs to convert from vw/fakra to iso

Yes mate - when I said radio adapter I meant aerial adapter.
Hopefully by next weekend they will have turned up and I can get it all fitted - just need to decide on a compactish sub/box/amp combo for the boot now..... :undecided:
-
It looks as if all your questions have been answered.
Do you know what sort of sub / amp combo you are going to get? My Punch ones are reasonably compant. You could easily get away with having just one but Im greedy and wanted two lol :D

Not decided on Sub and amp yet - for 8 years, until I sold my last car with it installed, I had a Rockford punch 10" sub with punch amp, and it served me very well! Fantastic bass for such a small enclosed box.
There is so much out there on the market it's hard to work the best bargains - especially as I don't really want to spend over £200 for the lot. :grin:

You are going to need to do some really hunting then. I was lucky and got my stuff for mates rates of a friend and got all that for £195 :)
-
Well after a recommendation off a mate I went and ordered this:
http://www.caraudiodirect.co.uk/dynamics-pack-p-6530.html
My leads turned up today, this should be here tomorrow! :)
Now I just hope the weather on Sunday is nice cos I don't have a garage any more. :(
-
For £200 all in you cant really go wrong ! Good luck with the fitout on Sunday.
-
Well it all turned up at work - looks good for the money - now I just need to get it fitted - depending on the weather etc, and if I can't find one online already - I may take some pics and do a "How to guide for fitting a Sub into Golf GTi with minimal effort and not taking the whole car apart!!!" :)

have u already got an afternarket head unit?
EDIT: yes u do :p
