So, back in July Cumbrianmale (VOC forum username) & I fitted an amplifier and loom (with Cm doing the 'working out of wiring) for the radio cassette. Leaving me to 'just' wire in the rear speakers.
I started of trying to source rear door cards with speakers fitted over here on Frenchy Volvo Forums.... but nowt turned up.
That left me with cutting my current door cards, something which I wasnt overly confident to do, lol.
The cards were marked 'where to cut' for 4" speakers, but I had 5.5" which will not go in that location.....
On Monday I popped up to visit another VOC forum member & friend on his hols here & between us we managed to cut out the cards. The speakers had to go quite well back, so are a little tucked away by the rear seat bolsters.... but still has a 5-6cm gap. Sound is not at all muffled

. Sound quality is much better & even with my old personal CD player hooked up to the cassette slot (remember those) I could wack the sound up & no distorting. I have an old mp3 somewhere, will have to charge that and try it...
Anyway a few pics to add to my blog:
Door Card Cut:

Speakers Fitted, nuts and bolts & a touch of loctite to stop the nuts coming loose:

Speaker and Grill in place:

Whilst the door cards were off, some waxoyl type stuff added:thumbs_up:

Pulling the wires through:

Wiring into the block from the amp' - we hung the amp way down and out of the way with zip ties:

And the final 'look':
