HELP: UK X3 E83 MSport sound upgrade

Thanks to everyone's contribution on this thread that has helped me to live with the sound quality from the X3 especially - Evlengr


As some may know the UK X3 E83 with the standard sound pack (Business CD) is extremely poor. Just single cone speakers (no tweeters) and no AMP or DSP.

At the moment I have just upgraded the door speakers to the UK Alpine SPG10C2. No 400/410's here. The sound has improved greatly in terms of clarity & definition but I still feel there is room for further improvement. Looking into swapping head unit.

MacAuddio Star X 2.10 - what an immediate change!

Dear Everyone,

Thanks for all the information found in this thread, this gave me the courage to swap the OEM speakers to a pair of Star X 2.10 component set!

Oh boy, what a dramatic change! I'm finally a happy and proud E83 owner! Treble is back in the car, with clearly more bass. I know I'm not a real audiophile, so it might not be even close to any "standard", but for me... it's everything.

For those who are only in the consideration and information collecting phase, a few words about my install:
- I had to really tweak the housing of this tweeter. I had to cut off 1 cm of the total diameter, which means 5 mm from the perimeter. Hand pruners was my best friend at this point, since I didn't have any finer tool close to me After altering the diameter, it just popped in and clicked
- second serious problem I faced was when I screwed back the bolt holding the woofer. At the very last turn of the wrench the thread simply broke I was really pissed - and careful with the rest -, never would have thought that this could brake that easily.. anyways, the two other bolts still hold it very firmly, so I'm not worried.
- keep the BSW E83 speaker upgrade movie on youtube on your screen, that helps a lot (if not else but only watching him how easily he's doing the disassembly )

So, it was absolutely worth and fun for that 4,5 hours (I know, I know ) installing it, I recommend it to everyone: do it, you won't regret it, and it ain't that hard as it might seem to someone!

I only swapped the fronts, and it's already enough at the moment. I might do the rears, too, but for me, amp upgrade is definitely postponed a bit now, I'm happy.

Thanks again everyone for sharing knowledge!

Hi guys!
I guess I'm new to this forum, although I've been creeping around for a while.

I'm interested in upgrading my sound system. My plans are to swap the door speakers with Alpine SPS-400/410s.
I would also like to add more lower bass, probably in the form of a enclosed 10"/12" subwoofer in the boot, powered with a monoblock.

My car is a '07 M-Sport 2.0d with the standard Business CD HU.

Can someone please clarify what I need to do this, and how?
Especially how to tap sound from the HU into the amp for the woofer. :S

Regards, Sanderpewz

Is a 2006 X3 prewired for the premium sound system so I could just get the speakers from BMW?

Thanks so much for the posts. Very much appreciate the sharing of your expertise.
I've read through this Sound System Improvement thread, and unless I'm missing something, seems the advice would be different for my 2005 X3 2.5i with the premium sound system because it has navigation.

I have had a CD stuck in the player for about a year. It will play, but although I can hear it trying, it won't eject the CD when I press the eject button. I've tried everything I could find on line to dislodge it. Even if I did get it out, I wouldn't trust the unit not to snag another CD in the future.

I left the car at Best Buy last week to replace the radio/single CD player. They said they would have to bypass the digital amplifier and knock out the navigation to replace the deck ("head unit," I guess it's called here). I called the local BMW dealer and they said there were no real radio upgrades available for this car, but you can replace the factory radio with the same one (PN 6512915059) for $872, and add some kind of auxiliary input cable. I'm hoping one of you fine people can help me with the following:

-Is the factory radio really the only replacement option? I was hoping for a USB input, satellite radio option, etc.
-I have not kept the NAV CD up to date. If there is an upgrade available for the radio, would it make sense to also upgrade the NAV? Seems items on crutchfield.com pair those up.
-Are there any options other than the dealer for purchasing the replacement radio from? If so, anyone have suggestions?

Many thanks for any advice.

All,

Just swapped the speakers with the infamous SPS-410s. I got them from Amazon and paid 82.00 for the two pairs shipped. :-)

The improvement in quality is very noticeable. I can't quantify or objectively certify the improvement but it was well worth my 82.00 USD investment IMHO. I am not an audiophile but like to hear clear and crisp music. The swap with some Sound Dampening material installation achieved this.

My main goal initially was to do an overhaul (speakers, mid-bass speakers and amp) and right now I am re-evaluating. I believe that the sound, although not perfect and a lot more can be extracted with an amp.... It is VERY good.

Not sure if it is worth the investment of 600.00+ for the Earthquake woofers and the amp from my point of view and goals.

By the way..... My X3 came with an OEM Amp and 8 speakers made in Hungary. So, I am assuming is the HiFi setup.

Swapping the speakers for the Alpine SPS-410s is definitely recommended! You can't beat the price on these speakers against the improvement in sound.

CanadianSolo,

I would suggest getting an aftermarket system like Dynavin to compliment the OEM equipment. See Youtube link below.



If you want to improve music quality.... Need to upgrade speakers (This thread talks about some potential upgrades or bavsound.com), mid-bass speakers with some Earthquake sws-8 and a 6 channel amp like JL XD600/6.

If you are really lost on the discussions in here.... I would suggest to find a friend that is an audio savvy or rely on a canadian reputable shop.

Hope this helps!

Just be aware that you will NOT see the screen of the Dynavin in bright sunlight. Reflections of the car interior in the screen can be minimised by appropriate screen overlays but the screen will still wash out in bright sun. There are reviews on this forum so I will not repeat more here.

Talking Amp Install

All,

Today I installed the JL xd600/6 and the result is awesome. A lot better than the OEM amp.

I used the Tecnic harness for a plug-n-play and clean install. Really straightforward!

The amp was installed on the same spot of the OEM amp with only one screw, some heavyduty doublesided tape and a couple of tieWraps to lock the amp in its location. I know it is not the cleanest install but it was the best I could do without having to do a custom fabrication.

So... The amp with a set of Alpines and it is really kicking a$$. For the DIYers.... I got the speakers for about 85.00 for the 4 speakers, 75.00 for the harness, 270.00 for the amp used and about 40.00 on wires, fuse block and terminals. 470.00 total.

Look at the connector housing. The one marked as '1' is negative; '2' is positive.

I just had mine SP-410 installed over the weekend. It fit and worked. But I couldn't justify the work and sound quality improvement. Mine speaker was broken, so I had to replace anyways.

By the way, my headlamp appears to be "broken" after I put everything back together. The "lamp defective" indicator came on after I start the engine and put car in gear. But after a trip to Costco, the indicator went away the next day.

Don't know what happened there, but looks like it fixed itself.

I want to upgrade amp/speakers in my '06 X3, how can I tell if it even has an OEM amp? not sure where to look. I see the pic, just hard to tell where you are in the car.

only thing i do know is the stock system sounds lousy. doesn't even have tweeters as far as I can tell.

also add CD Changer is a harness is waiting.

most likely I will just concentrate on the front speakers and the woofers under the seat, so maybe a 4 channel amp.

thanks for any help!

They all have amps. Two different kinds were available (base and Premium DSP). If your amp has diagonal cooling fins it's base. If they're straight then you have Premium DSP. The amp is located behind the panel above the left wheel arch.

If you have the base system there are tweeters in the front doors but not in the back. Premium has tweeters in all 4 doors. All speakers in the Premium are upgraded from the base system.

HIFI is base, TOP-HIFI the the Premium:

Lack of an item/part number means it's not included even though it shows it in the diagram.

More good info on good BMW, clean, stereo upgrades can be found here: http://musicarnw.com

Here are the specs on the Premium DSP system if you have it. It was optional so unless it was ordered that way you don't.

Thank you for this info!

I definitely have the base system, does have tweeters, not in the sails, in fact it doesn't look like they made trim with tweeter sails for my car. ('06 E83)

Before i do anything I would love to get an Technic harness. I am hoping to get a reply on that soon.

I do not see that many direct drop-in replacement 4" component sets.

Fosgate makes one that will fit without any mods.

not sure about the amp yet, i know dsp is important, may not want to go that far in this older car. possible 4 channel class D amp only.

If I find a CD Changer on ebay, will figure out where it mounts!

Thanks again!

Kind of an out there question (and this thread doesn't seem to get a lot of action these days), but I was toying with the idea of putting a sub in the trunk by just using the section of floor just fore of the battery cover. Lots of people seem to be hiding their amps there and it seems pretty roomy. Other than the very obvious of having to permanently alter that section of floor and having a speaker in the way of loading cargo, what are the other problems with this?

Thought I would add my experiences to the list.

After reading very carefully through the thread a couple of times (I've never done any sort of car audio), I decided to do the head unit first, then speakers, and then decide where to go from there. I installed a Pioneer DEH-6700BT HU and it's been pretty awesome. You can change the color and even adjust the preset colors to get a dead on match. I also added the Metra Axxess ASWC-1 and it worked perfectly on the auto detect settings. This gave me more options with the sound, and a bit of a cleaner signal at low to mid volumes (read ahead for more on that). I then installed the recommended Alpine SPS-410 speakers in the doors. Much, much cleaner sound than stock, but there's still something missing...

After toying with the 5 band equalizer on the Pioneer HU, I got a sound I really liked. Mainly, with both the stock speakers and the Alpines, I was getting really harsh highs. I mostly toned those down and boosted the bass a touch. However, the Pioneer HU does have a small amplifier, which sends boosted power to the stock amp, which gives me some distortion at about 2/3 volume (40/62).

So with all that, I definitely need to go ahead and do a full on aftermarket setup. I'm planning on a 5 channel amp as well as replacing the 8 inch speakers under the seats with the Earthquake SWS-8XI "subs." I know they're not "real" subs, but I just need a little more beef on the low end, I'm not building a show car.

Of course now I'm also supposed to be saving for a down payment on a house, so it may be something like 6 months before I can spend money again. Oh well. Maybe for my birthday.

I'll tell you, I've had good luck using the stock under-seat woofers in subwoofer duty with a new amplifier. I have a similar Pioneer head unit in mine, and am using its internal crossover network to split the signals. When set for 100hz on down, the OEM subs have held up well. I had originally been convinced that I wanted to use those same Earthquake units, but after having done the install, I've never found myself THAT wanting. You might find that powering the rear speakers from the head unit, and using a 4-channel amp to power the new fronts and OEM subs works out for a pretty darn good daily driver system. I built my share of show car systems in the past, and I've been impressed with what a "halfway" upgrade has done for me in the X3. Completely bypassing the stock amplifier and its circuitry has been the key to everything - that and good 4" coaxials (I used Polk).

Thanks for the input. I was sort of considering that route.

What exactly do you mean by using the internal crossover network? I know there are two RCA outputs and one is for either a subwoofer or rear channel depending on how you have it set up. My thought was to run a 4 channel with the 4 door speakers on one channel and then run the other channel with the RCA input set for the sub. Obviously it won't run a high powered sub this way, but it could be decent for what I want.

What is the RMS you're running to the subs under the seat? I have zero idea what they're supposed to handle. Also, what amplifier did you end up using?

I just meant using the "rear" RCA outputs from your head in their subwoofer mode. I currently am feeding the subs 100W each. I have a four channel MBA Quart amp. I power the front speakers from the first two channels, and the subs from the other two. Because the OEM sub drivers are 2 ohms, most amps are only stable running them from a single channel.

I use the head unit to power the rear door speakers so that I can still use the fader control to balance things front to rear; something not possible if you connect them all to one pair of left/right channels in your amp.

Very interesting. You have me thinking more and more about this idea. If anything, should I want more, I could just add a mono amp to the 4 channel setup. Could be a logical next step to see what I can get out of my current setup.

What sort of frequency range do the stock subs have? I can tell they really aren't doing much with the stock amp. I'm mostly used to a Pontiac Vibe of all things that had a factory system with maybe a 10 inch in the rear. The BMW sounds better so far overall, it's just missing a lot on the low end in comparison.

I'd say the range is "usable," but now you are the one who has me thinking... I have noise generators and RTA apps on my ipad and phone, might as well get a measurement, right? Will do that this week.

Ha! We're both going to get ourselves in trouble, now. Let me know how it goes. The Earthquake subs only went down to about 20 Hz anyway. I'm not even sure I need more than that, really.

The more I think about it, I'm thinking a 5 channel amp should simplify things as far as install and I could just see how the stock speakers do. But again, I need to watch my budget. Maybe if I can get a couple of things sold...

Hi all. Just got a 2010 E83 Euro spec with Business CD and want to upgrade the speakers. There is no amp on the left side to the trunk.
I'm going by the advise of getting the Alpine 410s.
Don't think I will need to replace the subs or add amp later as I usually don't need high volume just better audio quality.
For those who don't have amps would you recommend replacing only the front speakers or the four speakers?

Here is a photo of the place where the amp should be:


I also do not want to cut any stock wires what is the part number for the speaker plugs for the doors?

Thanks in advance.

The amp will be further forward than there, just over the wheel arch behind that panel that is not so readily removable.

Peek in there and look for something with fins on it.

I know the base Euro spec doesn't have one, but if you have subs doesn't that mean you have the upgraded sound system?

Although with the 2010 model all sorts of final-year changes were being made - presumably to meet price targets as opposed to making use of what was available in the winding-down parts supply chain.

On the avoidance of cutting wires, somewhere buried in this long thread is mention of getting standard connectors that fit the 410s and using the blue wire splices that just bite through the insulation enough without damaging it.
