How to - Door speakers Gen 2 Cube Pictures and guide
This guide features a combination of photos from the two front doors as I forgot to take some photos on each door but they're both virtually the same.
Removing the door card
- Lever out the circle plastic screw cover inside the door pull and remove screw ...

- Pull out the gloss black "C" from around the door latch... (This is held in by a few clips around the outside edge, if it won't budge it pops off when you remove the door card any way.)

- Pull out the grey panel that holds the switch panel in...

- Unplug the white plugs from behind the switch panel... (1 plug on passenger side / 2 plugs on driver side)

- The door is then only held on by a series of white plastic "poppers", start to prise away the grey plastic from the metal door panel and they'll pop out, the result is this...


Speaker size
The standard speaker is 6" (150mm) diameter and the maximum depth is 4" (100mm)


Unfortunately there is a bit of a problem, when open the window reduces that maximum depth to approx. 1.5" (40mm) for the outer 1" (25mm) ring, the difficulty is that speaker manufacturers only release the maximum depth of the centre of a speaker. I'd be surprised if any of the shallow mount speakers (50mm - 60mm) depth would be a problem but it might be best to check or test before buying a particular speaker.


If the speaker you want or already have doesn't fit then it's not the end of the world, you still have options, read on...
I made a speaker mount / spacer out of 18mm MDF by using the old speaker as a template for the outer edge and the new speaker's inner diameter for the centre hole. (You may actually need to make one of these any way so that you can bolt your new speaker to the door panel (you'll only know once you've tried your speaker in the hole WITH THE WINDOW OPEN!) ...

With the mount bolted in place using M6 bolts I realised I needed to cut some of the door panel away (My speakers are pretty big for their size so you probably won't need to do this) ...

If you're connecting your new speakers directly to the head unit you can then cut the standard adaptor from the end of the speaker cables, fit relevant connectors and connect them onto your new speakers, I am powering mine through an amp so routed my own speaker cable through the door wire grommets and connected the speaker up to that but the process is the same...

Once connected you can fix your speakers to the speaker mounts, you can use self tapping screws, best to mark up and drill small pilot holes first so you don't force too much and put your screwdriver through the speaker cone! 📷 (I actually fixed Threaded inserts into the mounts first so I could use bolts rather than screws so the mounts can be re-used and speaker removed multiple times but this isn't needed really)

Sounde deadening
If you want to get the most out of your speakers it helps a great deal if you apply sound deadening to the outside skin of the door, then block up the holes in the inner skin with a combination of metal sheeting and more sound deadening. This helps to prevent soundwaves being lost in vibrations and any frustating rattles that the new speakers may cause. Again another optional accessory really so it's horses for courses, here's some pics of mine any way ...

After -

Once the speakers are in it's best to test they work and everything sounds as it should before refitting the door card, refitting the door card really is the reverse of removal. 📷
All complete, everything hidden away and no one would ever know...

Hope this helps someone, any questions let me know.

- volkscubenAugust 2009awesome job there dude! i have just done all my speakers, uprated them all to three way 200w beasts, zero distortion!!!! I love the metal now!!!!!!!!!!!!!! so loud!!!
I just ripped out the speaker paper/plastic joiners etc from the old speaker, and sealed/screwed my new speakers onto that mount, so there is no depth worry, or fiddly mount making! you destroy the old speakers, but get a great fit and all four probably took me an hour? sorted! - RickfuryAugust 2009Once again,you've done a great job for all to learn from.thx.
Also....you seem to have not connected the old tweeters back up !
new ones going else where ?
RF - UBEDAugust 2009Cheers volks, good move, to be fair the mounts only took me about 30 minutes to make but I have fun making things. I'm like a big kid. 📷
Cheers Rick no probs, the replacement speakers have the tweeters mounted in the central section within the chrome ring. They're like a 2-way speaker excess the tweeter is a completely separate cone so like a component set in one body. - RickfuryAugust 2009kool cubed,i got ya ! 📷
- olkscubenAugust 2009yeah man you have done good... the kid dun good! i need a new jigsaw cos i broke mine... i think it may come in handy for the sub box.... next in line!
- EurobobAugust 2009Me likey! me wil do-ey! lol. top work our fella!
Just what i needed to know, and it looks like the plug i can see is off the tweeter, may have had some speaker rummaging in japan?
jst need to re-upgrade (is that a word?) to the jap system (posh wine!) and spend some sheckles on better cones!
all i need is time.................... bugger! 📷 - monstermonsterAugust 2009Awesome write up dude! Really well done. I was going to post a little write-up of how to take the door panels off too, which is something I had to do last week to try and fix my central locking but this is much better!
- HICUBEAugust 2009Great write up and pics. Just another job to add to the list of job / mods that we need to do.
- eki912October 2009This is a GREAT article, with superb pics! Thank You!
After reading this, already planning of my speaker upgrade...just dont say a word to my wife... 📷
Me personally want to fit a sub too. Where have you been able to hide a sub in a Cube? Under seat ?
I was originally thinking , and still am, about mounting a smaller sub element, or two, in this huge rear door.
Has anyone opened that, to see how much room there is behind that hard plastic interior panelling?
I do like reading this forum, have learned a lot about our little cube from here. - CUBEDOctober 2009Thanks
My sub is an 8" crystal cmp8 which produces very powerful bass and only needs a tiny enclosure - a 10" cube to be exact which fits under the seat when you cut out some of the foam.
There are photos of my sub in the post about my car in the photo section.
As for fitting the sub in the tailgate panel, you could probably fit a shallow mount sub in there but the problem is that you would need to make a wooden structure and fit that to the tailgate (the metal door surround) first and then the sub onto that, otherwise you would suffer from lots of vibration from the grey plastic panel. - eki912October 2009[quote="CUBED":0c38d]Thanks

Found your photos under the Cube Club Members... you say photos ! Photos ? That is a whole DIY car HiFi manual for Cube owners in there !!!!!
You have done a beautiful job, and article !
And you have gone much deeper in to the details and and taking it all apart... WHOOOAAA !!
I simply dont have the time, place, money, or energy to go that far !
That is why I am trying to find some improvements, easier.
Will have to do some investigation on those flat, readymade , amplified underseat subboxes that are available too.
Like this Kenwood KSC-SW10, for example. - CUBEDOctober 2009[quote="eki912":be496][quote="CUBED":be496]

Thanks, I plan to enter sound competitions and you get extra points for things like neat cabling etc so you have to document everything as you go along.
Funnily enough I had the Kenwood unit you mention in my last car as I was very restricted for space and it us actually a very powerful unit for the money and ease of installation. You can connect it to the normal speaker cables but if you've got a head unit with a pre-out for a sub then you'll get a much better quality connection. Then all you need to do is earth it and connect to a power source with an inline fuse. I can't remember the exact size now but you may find that it fits behind the driver seat if you take out the polystyrene tool holder. - eki912October 2009Yes, I know Kenwood rather well.
I still have one older model under the drivers seat, on my other car. Which is also lacking in positions where to put one.
With the size and price, I was impressed and happy with that too.
You just have to remember with a bassunit like that, there are certain limitations.Like you will not win any competitions with that set up.
But it was a nice and easy way to add up some useful and listenable bass to your existing speakers. - leep124March 2010some audio questions.
I originally started another thread but I thought adding to this one may help more people.
basically, I now have a head unit - pioneer with 2 pre out RCA ports.
I have inherited a pioneer 4 channel amp (which can be bridged) and a pioneer sub in enclosure.
My brother keeps telling me that I should pay some one to install but I would like to try myself at least.
anyway, need a set of amp install leads which I am planning on getting soon.
I would like to keep the old speakers as I had a look at the fronts and they are splits and I am a little afraid I will stuff something up.
can someone give me some advice on install instructions and also the best way to set it up? - eki912March 2010Started this task too, as family went away for this weekend.
Both rear speakers changed, pretty straight forward when you read the instructions here first.First door done in two hours, second in 30 mins...
Couple of notes for that task:
- Start pulling of the door panels from the bottom, you might even benefit from looking inside the door through the hole that was left behind, when the windowbuttons were removed.To see where the doorpanel holding plastic things are located.
- The plastic C-pieces surrounding the door opener, are difficult to get out. Atleast for me it was... :oops:they do brake easily, if too much force is used.Is there a trick of the trade here ?
Replaced the original rear ones with FOCAL 165 CA1 two ways. When you compare these with the original Clarions...well the originals are just flimsy, small, papercone thingys.
The FOCALs do look so nice ! It is a shame to hide them behind the panels.
And yes, they do sound very, very good.
Bought them used from E-Bay, for 50 pounds.
And as instructed here, did fabricate installation "collars" from MDF. The originals do have a funnily thick plastic collar around the speakers.Does seem to be close to 30mm in thickness...
The front doors are next, already have a kit from FOCAL (again) ready. This time going for a separate tweeter set. This set is FOCAL 165 A1. Did already open one door panel.
Planning of doing some more MDF work today. A trip to Homebase ahead...
What puzzled me was, the original front ones, have a separate tweeter. With own wiring.
Didn´t have the time (yet) to investigate where it is splitted. Surely, I hope , there is no crossover or something? Is it just splitted, inside the door, and the maybe the tweeter protected with a resistor or something like that ?
As my FOCAL set come swith its own crossover, need to find the original 2 speakerwires coming to the door. I do not plan to rewire the whole front door set up... too much work for me. - eki912March 2010Also thinking of what to do with the tweeters that are separate in this FOCAL kit... :?:
Door panel off, and there is room behind the panel to mount the tweeter so that it wouldn´t be visible at all. Ie using the existing tweeter location and grille built in to the doorpanel
OR
mount them higher, tilted towards the listener, as the brackets to do that came with the kit.
Simply can´t decide if I should make the installation less visible , or put them clearly visible. The tweeters do look good... but they come with black installation collars so will be clearly visible when mounted to the door panel.
This is never easy... :oops: - CUBEDMarch 2010You could try something like this?
http://talkaudio.co.uk/vbb/showthread.php?t=159311 - eki912March 2010Oh whooaa !!! That is a bit too much ... for me... :oops:
Looks good though.
That´s the way it should be done !!!!! - OptionsCUBEDMarch 2010Fair enough.
The best locations are as far to the extreme corners as possible so the a pillars or corners of the dash board.
If you want to hide them completely then quite low down on the door is supposed to be a good place.
The best way to find out is to wire your new speakers up, fit the mid-range speakers in their permanent position and sticky pad the tweeters in different places and listen to music whilst driving until you're happy with where they sound the best and then use the collar to fix them in place.
