The front factory speakers in 124 were never brilliant anyway. Given the age of even the youngest still on the road, they are beyond their useful life.

You can go and buy custom fit Rainbows for lots of ££.

I bought some new old stock 4" Infinity Kappas off ebay for £28 delivered and set about fitting them.

The speakers are accessed by prying carefully up at the front (lower) on the trim piece between the grill and the dash, and removing the trim piece. This part and its clips are fragile. This reveals two screws, which when removed allow the grill assembly to be wiggled out.

The speaker is held in with two metal clips - carefully pry the whole assembly out, and remove the wires attached to the spade terminals.

This is what you are left with:

You have to make it look like this by cutting through the basket and pulling the speaker apart.

This is messy - the glue used to hold the cone to the top is black and gloopy, I had to scrape it clean - it needs to be clean to take the glue you are going to use next.

You end up with this:

I filed four flats in the raised part - you can make them out in the photo.

I then epoxied my new speaker in:

Before you set out to do this you must ensure that the speaker you buy will not foul the grill, you need a very small top clearance.

When the epoxy is dry I will fill the gaps around the sides and the job is done.

Were I to do it again I would buy 3" speakers, and glue a thin piece of round ply into the rebate of the old speaker, and then mount the new speaker in the ply.

nice 201 2.5D 1993 & very nice 129 SL500 1994
Nice pics, I did much the same with 100mm Sony units, XS-F1025 @£20 the pair.My adaptors were made from a cut down 100mm grill plastics backing (half the thing thats supplied with them) glued into the std recess. There is just enough clearance above and below the speaker chassis the sony unit is 44mm deep.

I am impressed with them,their performance is quite adequate and much better than the aged Blaupunkt units they replaced.
