OEMAudio+ just confirmed via email they are not utilizing the oem subs . System is planned to release shortly. Guess I'm going Audison.

I was just told by them the other day they plan on releasing in May...kinda funny since they told us originally it was to be released last Sept...Anyway I'm really disappointed with their approach and don't plan on purchasing anyway...

Made some decisions on my audio system and commenced some work
So far to keep weight down and simplify the installation somewhat I decided to go with the following.
I am somewhat hoping a single sub and two door speakers will be enough. If not I will buy another 10 inch subwoofer and also add the additional two speakers behind the seats.

So the centre channel and the rear speakers will be disconnected for now.


Components are:


DA-G2.PRO MOST25 - Take out the OEM amplifier and simply plug this unit in, in its place and you can run any amplifier you like, set time alignment, dsp 10 channel analogue out fibre out.

amplifier yet to be determined I have a 4 channel Alpine I want to try first.

Single 10 inch Audioson Subwoofer - APS10D
https://www.audison.eu/products/aps-10-d/

Door Speakers - MUSWAY CSB4.2C BMW
https://www.sound-tech.com.au/csb4-2c/

So I have removed the entire rear OEM subwoofer section built a shallow (to spec) box for the 10 inch subwoofer.

Used rubber backed boot carpet for behind the seats trying to keep the weight down(not use timber). Cut to size it magnetically attaches to the subwoofer box to hold it perfectly in place and can be removed in seconds.

Made carpeted covered foam inserts to fill in the sides.

Made a panel in the trunk that magnetically attaches to the sub box and original metal brackets

It can all be pulled apart in seconds if need be.

I have not installed the electronics yet.

I think the weight would be similar to OEM.

Next week I will start the wiring and connection.

I am driving around only playing through the front, rear and centre channel as the OEM subwoofers have been removed.

I did not want to take up any more room the height is marginally taller than OEM. 1 inch

Its solid no rattles and creaks infact it eliminated some noise I would hear from time to time in the rear when going over certain bumps.

I was thinking of putting a couple Audison 8" reflex subs on the deck with ports.

I have done my research and found the below components to be what I'll need for my audio system replacement.

Audison bit DMI (replaces factory amp)
Audison APF8.9 bit (will install between the subs, or within the driver side cavity of the trunk.)
Audison APBMW K4E (2-way passive fronts): running ch1 & ch2 @85w rms 4-ohms
Audison APBMW K4M (2-way passive rears): running ch3 & ch4 @85w rms 4-ohms
Audison APS 8 R (left sub): running ch5+ch6 bridged @260w rms 4-ohms
Audison APS 8 R (right sub): running ch7+ch8 bridged @260w rms 4-ohms

This system will be a drop in, plug and play setup with a custom ported sub box replacing the oem sub shelf. Will need to schedule a time with the shop for an estimate.

The shop should be able to source all Audison harnesses to match up with our BMW harnesses to make it easy to return to stock if needed.

This setup I believe is appropriate for this type of car considering it's nature of needing to be light and not take up precious cargo space.

The bit DMI will work in the car with a quick software update coming out this week.

Or you can just go the full integrated MOST amp solution which will save you time and space https://mobridge.us/product/mobridge-most25-amp/

Thanks @mObridge.

Are these specs real (rms)?

• 6x 175W Channels @ 4ohms
• 2x 300W Channels @ 4ohms
• 1x 500W Subwoofer Channel @ 4ohms (or 1000W @ 2 Ohms)
• 1x 4V RMS pre-out

Will you provide the necessary harness to keep it plug and play?

What would this cost?

GO Mobridge. I can vouch for them from my expereince. Latest firmware works perfectly and its plug and play.

I installed the pro preamp. https://mobridge.us/product/da-g2-pro-most25/

10 channels preamp outputs. You have full control of the output.

Channel mixing for centre and subwoofer, output level control for level matching each speaker.

main output level control. Time alignment, crossover points, slope, you can adjust the frequency curve to boost or lower output in certain freqencies. Just about everything you need to fix the signal. Also the phone, NAV, warning chimes levels can be adjusted and you set which speaker you want to play them out of or all speakers.

You simply remove the existing OEM amplifier and ASD module and plug the fibre optic cable into this small light mobridge unit, plug in your PC and set it up very easy and quick.

The mobridge unit slides under the bracket where the ASD unit fitted.

I did not cut a single wire and can return this to stock.

Currently I am running a single 10 inch Audison Sub and two cheap Kicker coaxials in the doors all driven off a cheap Alpine 4 channel amplifier. This simple cheap system was a trial run before I spent more on components however it sounds far superior to the OEM in all areas and is far louder. TBH I could leave it as is, its that good. Essentially thee speakers.

I am also keen to move to Mobridge Amplifier add another 10 inch sub if it fits and run wires to the doors for a full active system controlled by the mobridge software.

Here is the Alpine amplifier and Mobridge hidden behind the left panel in the trunk.

Just a few more points added to my previous post.

I am inexperienced at this. If I can do this everyone can. To tap into the speaker outputs is so easy. Its one connector that carries all the speaker leads. I simply used a crimp tool with a single end connector (not sure what to call it) that plugs into each socket of the OEM speaker multi connector, as I was only tapping into the front speakers. I used a new speaker cable run for the subwoofers.

i did not have to splice the wire or cut anything.

The mobridge unit carries the 12V signal that needs to be used to power on amplifier and it works perfectly. The software tells the mobridge when to do this.

GND is present in that area and positive lead (see my picture) runs from the battery and does not interfere with the base board or panels due to its thickness.

I purchased these

https://www.ebay.com.au/itm/154190517160

Found the perfect size that fits the OEM factory Speaker connectors simply plug them directly into each single socket in the multiconnector.

I used a 9V battery to determine the polarity and which wire goes to which speaker.

They fit nice and snug and take a second to fit with the crimp tool.

I wonder if a Technic PNP harness could solve this too?

I thought that too but their website doesn't have enough information or pictures to qualify anything.

Yes the specs are real. The amps are left over surplus from an OEM project. Its a lot of power and was crazy over specced for the OEM.

We have a full plug and play harness for this and the BMW


These have been fitted to a number of BMW's already. Here is a review https://www.diymobileaudio.com/thre...-installation-and-review.432510/#post-5914285

Its your easiest, fastest, most powerful and cheapest way to get the upgrade done.

@mObridge I did see the review and the reviewer mentioned different specs. I also called sales for this and he didn't mention that price and also mentioned these are most likely peak power numbers being advertised. The link to Technic never really works, you'll need to add details on how to get to the product you are trying to link.

Do you know if any channels can be bridged?

 

[H2O_Doc]

For those wondering about Technic PNP, here is what they told me (and their sub harness worked):

“Please enter 3-Series (F3x/F8x) -> Top HiFi(688) at the main page of www.TechnicPnP.com for the complete selection of products to integrate aftermarket amps and speakers to your particular OEM sound system. No other OEM system integration product on any other page works in your car.”
