*Soldering Iron (optional)

Here's everything I have.



fit the speakers into the adapters
As you can see we have a speaker adapter and a piece of foam



We need to put that bit of foam around the inside of the speaker adapter like so, (it's got a sticky back)







Now put the speaker inside
Then fix it in place with the four screws







Repeat for the other 3, sit at the table in the warm with a cuppa for that part.
Now to the car.
Remove the rear card and you will see the speaker is held in by one 7mm bolt.



Undo it and pull the adapter towards you, you might need a small slot head screwdriver on the side just to start it, (there is a little metal clip at top)



Once done unplug the connector, then cut it off,



take the wire that came with your replacement speakers (I tinned them)



then join them up to the door wiring using crimps The reason I used crimp connectors is I found the factory wire seemed liked it had been burnt and I couldn't get a solder joint, (I've done 2 J's now and both were the same).
insulate with tape and then hook to speaker and fit





If you want to add sound deading then I removed the plastic waterproof sheet and used this as a template.





Re-stuck the plastic sheet



peeled the backing off the sound deading
and stuck to the door (I used my hot air gun to run round the edges Tucpal says a hair-dryer works too)





Replace door card and that's one rear door done.
Repeat for the other side.

Front Door

Next move onto the front door really is much the same as the rear.



Remove speaker and repeat the steps for the rear
cut the connector off crimp new connects on tape up hook up to speaker and refit.

The sound dreading is so not straightforward, leave the waterproof plastic there and just cut patches to fit it.

Before you go and put the door cards on the front doors you might to check the centre speaker,
I didn't have the speaker but I had the wiring for it.

Please see how to remove head unit

once you have removed the head unit and screen you should if luckily find the wire for the centre speaker tucked away.





Just cut the connector off and add crimp some spades on or (wire with spades on).



To fit speaker remove the plastic trim centre of the dash
Run the wires up hook up to speaker and then fit speaker.





refit trim



any extra wire pull down and hid back into the hole you found the cable



Tweeters

Remove the plastic cover trim







undo the bolt to remove tweeter and adapter.





Un-clip and remove car.
There are 3 little clips like this just pull them back gentle one by one and remove the tweeter.



I had to adapt my adapters to fit my new tweeters (this can take some time).
**DO NOT CUT YOUR TWEETER ADAPTER** check before rushing in.







Once done you can refit the tweeters.





And then replace the trim



Enjoy your new speakers.
