Hello everybody from Spain, I'm thinking about the audio project for my E90...

I have the BMW professional HU.

I have two amps:

-JL Audio XD600/6: 6x75wrms
-Alpine PDX f6: 4x150wrms

I'm looking for a speakers:

-2 separate ways front door speakers (amp with XD600)
http://www.type-rsound.com/p/4508/audio-system-x100bmw
or
http://type-rsound.com/p/5103/dls-up4

-Coaxial Rear door Speakers (amp with XD600)
http://www.type-rsound.com/p/4244/audio-system-co100bmw

-2 separate ways Rear Speakers (amp with XD600)
http://www.type-rsound.com/p/4251/audio-system-r100

-Underseats speaker (amp with PDX F6)
MID: http://www.type-rsound.com/p/4279/audio-system-ax-08bmw
or
SUB: http://www.type-rsound.com/p/4509/au...m-ax08bmw-plus

-Trunk Sub (amp with PDX F6)
http://www.type-rsound.com/pm/2028/jlaudio-10w3v3-4
I want to make something like this:

What do you think about? Any recomendation?
-Is better to replace the rear door speaker or install a central speaker amp with the XD600??
-Do you think is enough with under seats MIDs or much better a SUB??

Thanks.

As far as the links go "No habla espanol" at least not good.
Looks like the first speakers fit and the second one ups need adapters.

Its important to establish which system you are starting out with.
If you have the stereo system as oposed to Hi Fi or L7 what you do will
be different. If you are starting out with the stereo system you need to get a frequency flattening device of recode the output of the Head Unit to Hi Fi.
Getting this done and a harness should be first on the list.
Most say don't spend a lot on the rear seat speakers.

Thanks for all the information.

I have the stereo system. I was on a caraudio shop, I want they install everything...then they told me that they have to install a high to low signal converter to get the RCA from the HU. Something like this:

I want to use both amplifier then I think the following:

XD600 will amplifier:
Front doors: 2 separate ways Audio System X100 (Installation with 3 bolts )
Rear doors: Coaxial Audio System CO100 (Installation with 3 bolts)
Rear: Stock Speaker

PDX F6 will amplifier:
Underseats speaker:
Audio System AX 08BMW (Its a woofer 80rms)
or
Audio System AX08BMW-PLUS 150wrms (It's a SUB like SWS-8)

Optional, Install a JLAudio SUB on the trunk.

Then the question is:

Install a 8" Wofers + trunk SUB ?
Install a 8" SUBs ? (Then I will have 2 PDX chanels unused)
Install a 8" SUBs + trunk SUB ?

Thanks,

Is it efficient the trunk SUB in this car?

If the 8 inch speaker fits in the under seats.
You might just want to do that first and see how it sounds.
If its still not enough bass for you then add a 10 inch or bigger trunk
sub and a nice enclosure of some kind.
If you are a total bass head you will probably want the trunk sub.
