The speakers were mounted on the rear shelf, with dynamat then fitted under the speakers preventing the loss of sound down through the shelf into the boot, and forcing it all to go up and into the cabin.

Similar answer to which I posted for 'front speakers', but I found a sony replacement speaker by taking out my old one and taking it to a car audio shop and asking them to match it. Got a pair of sony x - plods for the back but backed them up with a sub and amp from motorworld (cost 80 quid) 800 amp n 10",' rollin!!!; the only problem I had was with the speaker grilles...had to put them back on with double sided tape, apart from that no probs.
