Here’s a link to my post

https://z4-forum.com/forum/viewtopic.php?t=148411

where I have fitted the factory subs which may help, I’d suggest fitting a vibe 400.1m amp

https://audiovisualworld.co.uk/vibe-powerbox-400-1m-v7-class-d-mono-800-watts-rms-micro-amplifier.html

https://www.ebay.co.uk/itm/262348882339?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=hmkaGOdZT1i&sssrc=4429486&ssuid=JZNgRjNbROm&var=&widget_ver=artemis&media=COPY

and fit it behind the rear bulk head where the factory amp would be, you could probably use the wiring from speakers 5 and 6 (4” speakers), it also comes with a volume dial, I’ve fitted mine inside the arm rest so that I can adjust the amount of base volume.
You could power it directly from the battery in the boot and it with turn on and off from the audio input from the speakers.

Cheers again for the info. I think I may just go for the 4-way vibe amp and replace the 6.5" in the footwell as well as the 4" behind the shoulder.

As I said, I'm a bit of a noob, but presumably, only 4 channels will get amplified from the Vibe amp, how do I specify which speakers get amplified and will the door speakers just get powered from the head unit?
 
Also, will any 4-inch & 6.5" speakers fit (line up with the screw holes)? Regarding depth, I appreciate I need to be a little careful here.

No you’ll need BMW specific speakers or some suppliers provide adapter rings to go with their generalised speakers

Do the vibe 6.5" fit in okay and do they fit the wiring or is modding required?

After doing some research and wanting to stick with Focal, I think I'll go for a set of these https://www.focal.com/products/ic-bmw-100l driven by the Vibe 4-way amp. Next, I just need to find a suitable set of 6.5" speakers for the footwell, which is proving difficult in the focal BMW range.

I don’t think anyone makes a custom bmw woofer for the E89 most of use adapter rings ..home made in my case

That would explain why I can't find any. I will take a look at making some adaptor rings.
 
Oh, and what's the deal with the existing speaker wire? Will it have a BMW plug that will need cutting off?

Apologies for all the questions. Hopefully, these will help the next person :D

You need to order the Vibe amp with the wiring harness for the E88, then simply connect between the cars loom and the head unit on the quad lock connector, the 4 channels are
Channel 1 - front right footwell and door speakers
Channel 2 - front left footwell and door speakers
Channel 3 - rear right shoulder speaker
Channel 4 - rear left shoulder speaker

Brilliant, thanks. Just checking that was a typo and should read E89 wiring harness?

Since all the woofers I know don’t use a bmw connector it’s going to have to be chopped off and an appropriate new connector , usually a spade , screw terminal spliced to the original harness ..


Look here..

The space is there to fit them but you will need to modify whats there to mount them.
 
Excellent, I will look to avoid the BMW Focal's then, as it looks like I'm paying a premium for those and could get something better for similar price in their not BMW range. I'm sure I can deal with making/buying some custom adaptor rings.

Now the next dilemma is, will the amp be good enough, probably not but I'm not going to think about that.....
 
Please note..DO NOT use 6.5” woofers…they are too tight for the mount / holes…you can fit them but it’s a lot of messing around…6” straightforward..

Damn it, it took me ages to find the ones I wanted :) not sure they do a 6" version.

So, is it the depth that's the issue or the actual mounting point?

The outer edge of the speaker mount clash with the 4 screw holes for the BMW mount..it will require a bit of messing around..I found out the hard way on the 35is..I use Fosgate Punch 6" woofer on my 20i..to good effect

あなたの作業は完璧で素晴らしいです。
私はスタンダードアンプのしょぼい音ではオープンで海岸線をドライブするので爆音にしたくHi-Fiアンプに交換しました。
問題は配線加工が大変でしたが両方アンプを分解しました。
質問ですがリアスピーカーのツイッター追加はどうですか?良ければ追加しようかと思います



If, like myself, you have an external amplifier powering the rear midrange, then adding a tweeter each side will improve the sound quality coming from the back of the car. I hear the crispness of the rear sounds over my shoulder while driving, so I'm glad I added them.


Here are a few photos I took while adding the tweeters.

私のように、リアミッドレンジに外部アンプを取り付けている場合は、両側にツイーターを追加すると、車の後部から聞こえる音質が向上します。運転中に肩越しにリアの音が鮮明に聞こえるので、ツイーターを追加してよかったと思います。

ツイーターを追加しているときに撮った写真をいくつか紹介します。
返信ありがとうございます。
大変参考になりました。
検討致します
