Another question - which speakers do u recommend for the subs replacement? Are sws8's only available option regarding size and tech specification or not?

And what about rear speakers? They do not sound so much improved after upgrade? As i have understood, they are driven by the head unit, not amp? Is there any replacement for them as well?

Tnx!

Can anyone help? Please!

The Alpine won't drive the SWS8 subs properly, the mids are 90db and the SWS8s are 86db so will be too quiet.
You would have to add another amp to drive them.

The rears are EQ'd like mad, so no point doing anything with them.
Your only option is use a different amp, maybe a 5 or 6 channel and take the signal from the front channels and then split it in the amp.

Any alternative regarding SWS8? As i have mentioned, my car just got the Alpine upgrade, everything sounds cool, except the bass frequencies - they are not so much improved.

I've found the list here - http://www.e90post.com/forums/showth...highlight=SWS8

Most of them requires some extra modding.

btw. 1. any idea regarding silent pdc sensor?

btw. 2. this guy got the SWS8s and paired then with Alpine amp, um? -> http://www.e90post.com/forums/showthread.php?t=230960

Bump. Any news regarding silent PDC sensor after the Alpine upgrade?

gIzzE · 02-19-2012, 12:20 PM

What year is your car?

You may need it coding for pdc to match.

I have heard a pair of 2ohm sws8's being driven off the Alpine and I thought it sounded worse.

I have got a JL XD400/4 amp that I bought off here, great amps and my favourite Class D amps, but thinking it may just be easier to add a second amp and some earthquakes.
If I do put the XD400 in I will swap head units, but do prefer the oem look, so a bit undecided.

I guess as it is a second car I don't want to throw too much money at it, and even worse too much time, I don't enjoy installing this stuff at all, just the results.

I know I could whack a Nakamichi CD400 in there with the JL amp and it would sound lovely, but I don't want to have a featureless system, which is what that will be.
As much as I want a nice sounding system, and if I admit it that is my priority, I still want all the gadgets etc. so I end up compromising and regretting it.

You can't be serious you are thinking of deleting OEM HU for reasons of SQ...once you are coded to HiFi, your upgrade options are unlimited.

The problem is Tai that I have the later prof unit with no most connectors, so adding usb and bluetooth is impossible.
I was thinking maybe going double din and relocating the climate to where the nav screen goes on the X1.

Then thinking maybe just fit CIC.

Then thought, maybe just swap the car for one with the right stuff in it!

I am really liking the X1 at the moment though.
Had a new clutch and flywheel fitted and feels so much better.
But still prefer an auto if I am honest.

taibanl · 02-22-2012, 11:47 AM

Ah gotcha...I remember you didn't want to fit the iPhone station because you might get a new car. I do love mine though.

For all you other guys...once you code to HiFi, if SQ is what you want, you don't need to replace the HU

Rudz · 03-22-2012, 05:39 AM

I call BMW Chandlers to have my HU recoded to Hifi, i've got the base system, they did'nt have a clue, maybe it's me not explaining things properly, any help on what exactly I need to tell them ?

Nigelo · 03-25-2012, 09:11 AM

In the middle of my install here in an 07 e92 - quick question though! How do you refit the interior sill after you pop it off the cream coloured clips. Do you pop the clips out, and refit them to the plastic trim before trying to refit the entire piece?

Thanks guys

Nigelo · 03-25-2012, 03:54 PM

Finished my install earlier on - I just went with gut instinct, pulled the cream clips from the car, slid them back onto the plastic sill cover and popped it all back on. I actually found the under sill wiring the simplest part, the bits I struggled with were:

- supporting and refitting the door card.
- removing the wiring clip from the oem speaker (nothing seemed to work, just fluked it eventually after 20 mins each side)

Actually getting the amp and its wiring sorting took as long as simply unhooking one oem speaker. Completely the opposite of what I imagined before I started. And getting the bloody door cards back on and the door lock button into it's hole.... Pain in the arse!

Hello to all. This is my first post but I have been around for a while and I would like to thank all for sharing your experience and opinions, for that I am very much grateful for the knowledge, in specific to this thread. It has made me decide to purchase the Alpine Hifi retrofit kit for my 116D E87 LCI in which I am very satisfied with the upgrade.

Thank you all for the info and the help.

bmminiparts · 05-10-2012, 10:09 AM

Hi all

I can email fitting instructions for this kit if needs be as i have a copy.

Send me an email request to sales@bmminiparts.com

raf555 · 06-07-2012, 07:12 AM

A bit of advice...

I have a 2006 E90 with pro I drive and standard system.

I'm think of getting the Alpine kit fitted but in addition upgrading the rear shelf speakers to Logic ones and perhaps also fitting the Logic underseat subs!

Would this work?

Cheers

gIzzE · 06-07-2012, 07:42 AM

Waste of time doing rear speakers.

The rear speakers are crossed over at 125hz and continue to run off the head unit, changing them adds nothing!!

The Alpine kit is worth doing, it adds a lot. If you want to change subs though buy a different amp and do it properly.

Will the alpine amp not be suitable for oem logic 7 underseat subs?

Dr Dave · 06-07-2012, 11:25 AM

Excatly the setup I have, L7 subs with the Alpine upgrade, sounds good.

Well worth doing. If you were closer, you'd be more than welcome to a listen.

Of course, you'd be more than welcome. If I'm ever up near Bristol etc I'll give you a shout - and you, likewise. I'm just off the M5 at J26.

Running a 61 plate 320d E92 M Sport here. I'm a bit confused as to whether this is still a viable upgrade? I do have some speakers left over from my previous car, but I know the component won't fit.

Am I right in thinking that the head unit recode isn't really all that easy any more on the later models?
