Ok folks, because Ive been asked by one person a while back and I just found a thread about them too, heres a tutorial. (note, i understand most of you can do this yourselves and have done so. this is for all those who cannot).

Tools Required: needle nose Pliers, side cutters, both kind of screw drivers, heat shrink, solder, curved file, drill and bits, pair of interior 5mm x 10mm broad head screws
Shopping: 4inch speakers
Time: 20min <

Removal:
1. MAKE SURE THE BATTERY IS DISCONNECTED (covering my own arse here)
2. being careful not to mark them in any way, remove the plastic trimming on the front window uprights.
Save the springs/screws because this is going back later.
3. being careful not to take chunks out of the dash, get a flat screwdriver and insert it into the gap facing toward the middle of the dash and pry off the plastic mounting and mesh (it should be just clipped in with plastic tabs.
4. while its hanging there, so you dont pull all the wire out of the dash, simply cut the speaker wires off the speaker at the soldered tabs.
5. flip the speaker and speaker guard over, notice how the metal mesh is attached to the plastic, by twisting the small tabs made by factory cuts in the mesh you should be able to separate the mesh from the plastic cover.
6. gently remove speaker from plastic cover.

Installing:

(I found that when I installed a pair of 4 inch 2way speakers(kenwood). the magnet was too big and the speaker sat too high for the plastic cover, so....)

1. if your new speakers are the same size reverse the installation procedure with the new speakers remembering to solder the wires onto the new speaker before clipping the housing back into place.

2. If (like me) you went out and bought some spanking new 4in kenwood 2ways then things are about to take a bit longer.
3. use the needle nose pliers and carefully break away the plastic that goes across the hole in a kind of (#) shape.
4. file the edges of the circular hole down neatly and smoothly making a complete circle with no bumps.
5. align the speaker by dropping it into the mount, when satisfied with the position, drill pilot holes so you can screw the speaker into the plastic cover.
6. chances are the metal mesh will no longer go back over the new speaker, so throw it away if you want, kudos if you can make it fit.
7. solder the speaker wires onto the new speaker, heat shrink the bare connections and click the speaker and mount back into its hole in the dash.
8. install the trimming and enjoy the new noise

This is brilliant, spent most of today trying to find shallow speakers to suit the magna with no success = (

Didn’t really take long to complete however if you don’t like soldering you can also use blue points or terminal strip.
New speakers should come with cables that already have lugs on them so its a matter of connecting new to old and dont mix polarity. ( if you want pics as a better example let me know)
Underneath the plastic there is actually a little pocket where you can poke your choice of termination down. This way in future if you need to replace the old speakers all you do is unplug them.

The screws / tek heads in my TS were 8mm, you can easily use a 1/4 ratchet with 8mm socket on the passenger side but on the driver’s side i needed an 8mm ring spanner, or regular if you dont have one.

another option is to get a set of 6" speakers, a pair of pods from a rada, and fit the pods to your existing door cards ( hole for speaker in the actual metal of the door is already there why not use it) this off course requires to annoying task of feeding speaker wire into the door via the existing grommits but worth while with much better results!

or buy the blue sony 4" speakers they have the smaller magnet that doesnt require the work :D

just picked up my 4th set of 4 inch speakers and a new set of 6s for my doors in my wagon as sumthin put a hole in my last set and 1 just stoped working

I was getting sick of the sound my 4" speakers were providing in my dash, so I got some new door cards from the wreckers that had the speaker pods on them. Took the covers off and attached them to my door. Cut a hole in the door card and made a MDF ring to hold the speaker on the door card. They sound really nice but because they were just mids I brought some Response tweets from Jaycar for $10. They lifted the entire stage up to windscreen level. Ther are the larger format ones, they fit with the covers reinstalled. I think they sound amazing, and for $10 I figured why not try them.

(Will get some shots of my doors tomorrow when the sun comes back up)

Great to see someone doing something different!
Are you using any type of crossover?

yeah bought an external 3way crossover off Woob, and also have a 10,000µf cap inline with them too, just incase.

With the KS door pods remove plastic mesh, then bring the speakers closer to the door hinge end. Shoot suggested this to my TR and it improve the sound of the speakers :) Will put photos up.
