Audiophile/Speaker Upgrade

So one of my next upgrades is replacing all factory speakers in my 07 335i. The trouble im having is 1) what are the sizes of the speakers "width and depth" 2) who makes speakers that i can purchase.

I have checked numerous sites and it seem like Morel and maybe CDT make speakers for this car but they are super expensive, dont really wanna spend $700 for aftermarket speakers. I wanted to go MB Quart or something like that but im having a real hard time trying to find anything that fits this car.

My other option is maybe going with a add on sound processor "like Alpines" and then add some 10" subs that i have and keep the stock inside speakers but im wondering if the add on processor with improve the sound quality of the speakers inside the car, kinda like when you upgrade a stock deck to an aftermarket and the sound quality improves immediately on any car pretty much.

Anyone do this yet or have any experience? im a real big bass head but definitely need the highs n mids but dont wanna spend a million dollars to replace the inside speakers if I don't really need to.

FYI for stereo upgrades go here

read this for starters

Can't give you bass advice its not my thing.
I can tell you there are no real cheap outs for this car because the
standard stuff doesn't fit the stock locations.
Spend more money on the front speakers than the rear's is a general
rule of thumb.
You are saying things that are kind of opposed you want and audiophile system
but you don't want to spend to much and you also want heavy bass.
People on the above board that have both a processor and upgraded amp and speakers
generally say the upgraded amp and speakers made a bigger difference than the processor.
Also people that start out with a processor like the ms-8 almost always add and amp and
speakers later as it doesn't have enough power to drive speakers with much authority.
You need to identify which of the three BMW systems you have before you do anything.
Also with the coupe the choices for door speakers are even more restrictive because the
doors are extra thin. About the only high end speakers that fit are Jehnerts and Focals.

The easiest solution is a MusicarNW kit but its not cheap.
Why its a known to work configuration and is well tested.
It comes with all the stuff necessary to put it together(speaker adapters wire harnesses etc, power kit) , requires no soldering or crimping , comes pretuned as much as possible.

im into high end speakers but im not trying to do a competition setup just yet.. just want something other than the stock and I have a coupe series with the L7 setup. Morel also makes speakers but the components is around $7-800. So you're saying to upgrade the stock amp with an aftermarket? If so, how many channels would it have to be? I will look at those other threads. I was interested in the Alpine PXH-800

If you have L7 you have a big problem with mods.

If you have L7 you have a big problem with mods.
The l7 system is the hardest system to modify.
Why because of the optical connection between the Head Unit and
Amp and the fact its a 9 channel surround system.
In order to change the system you pretty much have to get rid of the L7
amp and the only thing that will replace it is a mobridge da2 preamp.
Then you need 9 channels of aftermarket amps to power all the speakers.
The other solution is reprogram the Head Unit or Idrive for low level analog
output get and ms-8 , amps and speakers for the front of the car quite
a few people were doing that and still do pre mobridge da2.
There are just not that many company's that make reasonably priced
speakers for shallow spaces, and the few good ones are expensive.
There are some that are better but not so expensive but they tend to
go in an out of production cause the demand for 4 inch speakers is small.
I was conflicted about this myself for long time as I was used to buying
Alpine and Pioneer stuff at fairly moderate prices comparatively .
Also most of the stuff isn't close to competition stuff at the other site.

You could get BSW speakers and add sub amp and sub.
For a moderate improvement.
Other than that you really need to do your homework at the links I provided.
There is years of e9x specific experience there.

thanks for the info. I asked a buddy of mine who owns a car audio shop here in san jose about the Alpine PH800 processor and he said that I can add that to my stereo and it should improve the sound quality a little inside the car. Im assuming I dont really have to change anything else if I just add that and then add a mono amp for the subs im gonna put in. Changing the inside speakers seems like its gonna cost way to much and the amount of work needed to do this is just to great for me right now!

Unless it will work with BMW proprietary optical code its useless

(meaning the pxh-800)

http://www.e90post.com/forums/attach...1&d=1209780605

See the fiberoptic cable between the HU and amp.
How does he propose hooking it up.
The BMW head unit in the L7 system had no analog outputs and the L7 amp will not accept anything
but the optical output of a BMW head unit.
You better have him read this and look at the links here.

Has this guy ever done and L7 system its really different than anything else.

to be honest, i didnt ask if he's done the L7 or HIFI system upgrades but looking on Alpines website, they say it has 2 optical outputs and a digital to analog built in converter..heres a simple spec sheet on it

6 Channel Inputs Up to 10 volts, both RCA and speaker are provided.
Dual Optical Inputs Ai Net and Ai Net Aux.
8 Channel Outputs Fully active, 4 volts.
Equalization 31 bands per channel.
Parametric Equalizer 10 bands on front, rear and centre channel.
Subwoofer Parametric Equalizer 5 bands.
X-Over Slopes Up to 36dB/octave.
Signal to Noise Ratio 110dB Digital / 105dB Analog.
Digital to Analog Conversion 24 Bit, high performance.
DSP Dual 32-bit floating point operation.

Two optical inputs but no optical outputs

Two optical inputs but no optical outputs.( the optical output of the Hu is suppose
to be a proprietary BMW code not standard toslink which is not AI net which is
a Alpine Format.
So even on the odd chance it would understand the output of the head unit
the L7 amp still has no analog inputs to accept the analog output
of the processor.
So this is a processor if you tap the speaker out from the L7 then you still have to add amps behind the
new processor to get amplification.
I can't see anyway this would work without adding additional amplifiers after the processor for any channels
you want amped using the speaker out high level outputs from the L7 . An this seems like kind of a klugy way of doing things.

hmmm, maybe i need to call Alpine customer service and see if they have a fix for this or some kind of extra piece i need to be able to do this hook up. So it seems like it's going to be really hard to even just add subs in the trunk without having to do like 20 different modifications!

To add subs all you need is Technic sub harness

To add subs all you need is Technic sub harness
But you will need a sub amp , sub speakers and a enclosure.
To get a Technic sub harness you need to PM Technic on this board or the stereo
board mentioned.

Most stereo manufacturers that don't directly make something for a bmw , and there
are less than handful of those, won't know what you are talking about when you ask
them about a BMW L7 system.

Just get new speakers first - ensure they have decent sensitivity.

Today all amps are virtually perfect. Expensive amps can simply drive more power and remain virtually perfect.

Interestingly there really is such a thing a speaker break-in so give the new speakers a while. Infinity 6809CS (only $110 for the pair when on sale) sounded pretty bad in my Miata for months but now sound great (plenty good enough for a car system). At home I recently bought some Infinity Primus P363 floorstanders that sounded only ok for the first month or so.. now they sound great.

Component speakers kick out decent bass, but obviously not booming like a sub.

The Alpine PXE-H800 is a full system DSP, not a line output converter to add just a sub.

The H800 digital input is not compatible with the OEM MOST digital stream.

If what you want is to only add a sub to your Logic7 then: http://www.bimmerfest.com/forums/sho...4&postcount=51

Is there a reason why you want this particular setup?

The audio signal for most systems using the MOST fiber optic bus are heavily processed.

You're better off recoding the head unit to hifi which will allow you to have an unmolested signal usable by your aftermarket amp or processor.

I believe all you need to do is to remove the fakra terminal on the fiber optic cable and fit a toslink terminal.

In order to get a Toslink signal

In order to get a Toslink signal
you would have to use the mobridge preamp to translate
the BMW Most signal to toslink.
Go to the mobridge site for details.
Yeah its to bad there wasn't a standard for optical signals in cars
the way there is in Home Entertainment systems.
