I wanted a bit more clarity and a lot more oomph from my stereo - my old ears are struggling to hear the finer points of dialogue in The Archers when I have the roof down and a good B road to charge down.
The Hertz speakers I am using were recommended in the speaker thread, I've not yet listened to them but hope that they are good.
With that said, I suspect this method will work with any comparable speaker.
The stock speakers are Nokia/Haes 4ohm, and are fairly "built to a price", to my eye at least.
The speaker is attached with three screws, two pictured here:
And a single one at the opposite side here:
Potentially a thousand plagues lurks in this speaker mesh:
The accused:
Note the three attachment points:
There's an interesting cut-out here, by the single attachment point, which gave me an idea (more on which shortly):
This is the new unit:
I cut away the speaker from the retaining ring:
I then cut three further cut-outs in the retaining ring, spacing them equidistant from one another, meaning that there were then four cut-outs, which meant that the new speaker could drop in and be held firmly:
It's not going to fit into the grill with those tabs, so they need to be edited:
Then simply refit the retaining ring with its new passenger:
This screw barely bites into the metal tab which retains it, I'll use a longer screw if I can find one:
Old and new:
My next task is to teach myself basic CAD and create a digital version of this ring that can be run off using a 3D printer, as I have more of these to do and I don't want to have to cut up a speaker each time.
