I think the cars BEFORE 03/09 require the crimping, & the cars built AFTER 03/09 dont...

That's correct to a degree. But mine is an LCI model built before 03/09 so it was a bit of a gamble as to what I needed.

hi,

which alpine kit do i need for a 2010 LCI?

[jb111s]

Just completed this upgrade on mine.

I bought a post LCI version on eBay, hacked the connectors off and spliced in directly to my non LCI E90.

Wiring harness is exactly the same with the two versions, just the wires aren't quite long enough so had to extend the cables slightly by soldering on a metre of extra cable.

Works perfectly and improves the sound considerably. An essential upgrade!

Hi, first of all I would like to say hello to every one.
I've recently bought 2012 e92 m3 with basic audio (4 speakers and 2 subs) and didn't think that would be so cr*p.
After reading quite a lot about hifi in bmw I consider fitting alpine kit. So I went to my local dealer to order the kit and they said that they can order but I need to change right sub (buy another one) and wire it to right doors?
They sent me fit instruction as well and it is stated that it should be done for option 662 only.
I wonder why new sub should be fitted, as I have seen lot of threads about installing retrofit alpine with standard audio and nobody was changing right sub.
Anyone help?

I seriously doubt you need to change the right sub, I believe that is only for cars fitted with the Business HU which only have 1 sub and you need to add another bass but I'm sure a M3 would not be specced so basic.

Can you check what your head unit is? Is it the iDrive system or a BMW Professional one?

Alternatively, if you post the last 7 digits of your VIN one of us can get you a list of exactly what kit you need and what part number(s) etc!

Wrong info passed.
If you have m3 with cic then you just need alpine kit.
L7 subs add better / deep bass to system with alpine hi-fi kit.

Bmw has launched alpine kit for f2x / f3x which has 6 channels (rears are amped). Its around 500-600 but better executed imo.

[Bemer77]

Thanks for quick reply, I've got IDrive, navigation but no idea if its business HU. last 7 digits: E998234

[Bemer77]

Ok thanks I'll call them tomorrow

[Bemer77]

so I believe the part nr which I need is 65412163268 and of course tweeter covers which I've already bought.

[makkan00]

You have professional navigation with combox.

[Bemer77]

So it means that I need only alpine kit?

[Sbm007]

Yep 65412163268, if you've got the correct tweeter covers then that's all you need (mind you there are different ones for the E90/E91 and E92/E93 - as long as you've got the right ones).

The kit is pretty much plug and play and not too difficult to install on your own. You will need to get your HU coded to HiFi though for optimal sound.

Whilst you're at it, it is worthwhile upgrading the subs too.

[Bemer77]

ok thank you for help

hi Guys

collecting the new car tomorrow and unlike my previous E90 330D it only has the bass stereo so looking at the Alpine upgrade

this is available on the german ebay site

http://www.ebay.co.uk/itm/2214818890...%3AMEBIDX%3AIT

part number matches the post just above so that looks ok at £255 plus postage the price looks good as well, will only need to get the tweeter cover trims for the doors

i cant find a better price anywhere in the UK for this, my new car is a 2011 model so this looks like the right one

i also read that it will need coding after as well to complete the install. i have read quite a few of the guides on here so will be installing it myself, would the coding need to be done immediately? or will the sound be bad until its coded ?

thanks

Coding can wait but you will notice the improvement once done. As mentioned before in the thread this is a great guide:

Make sure you have some interior trim removal tools, the plastic ones which dont damage

[richk84]

£255 is about the going rate too

I was wondering if anyone can help me. I recently got an E90 that already came with the Alpine Hifi upgrade. Every so often the passenger side mid-range speaker and tweeter intermittently switch off and don't emit any sound.

The speakers then randomly come back either by powering the car on and off, slamming the passenger door or going over bumps but not always.

Any idea on what it could be? Loose wiring? Amp?

Could this be fixed by a local independent rather than BMW?

When they are working it sounds awesome compared to the stock speakers I have had in the past.

Thanks.

Could be a faulty amp or a faulty speaker triggering the amp's protection and causing it to shut down.

I had a faulty coil in one of my subwoofer's and it would cause the amp to cut off whenever the sound dropped below a certain frequency.

Fixed it by replacing the subwoofer.

You should try disconnecting each speaker one by one to isolate the faulty one (if there is a faulty speaker).

Otherwise your amp might be bust!

But since you said it happens randomly, and driving over bumps sometimes helps. It could very well be loose wiring! Worthwhile to remove the door card and inspecting the wiring and also the connection from the subwoofer undearneath the seat flooring.

I was going to purchase this kit for my car but BMW say it's not compatible. Looking further into it, it seems they're right as the car has ccc with dab. Apparently the dab module sits where the amp would go. Any thoughts? Not interested in dab so happy to remove it if that's my only option.

Sbm007 thanks for your reply. I will investigate this further. Over the past week it has been working fine and only gone off a few times and then come back suddenly. I am not very clued up on the audio side of things so may have to seek help from a local audio guy if the issue persists.
