i did my front speakers today in 30mins and i aint an expert either.
-Take off speaker grill
-unscrew speaker and unclip loom
-cut loom off the strip back the 2 wires
-crimp on two spade connectors onto the wires
-slide the spade connectors onto the two terminals on the speaker
-make sure each connection is wrapped in electrical tape so they dont touch and short circuit.
-screw new speaker on and replace grill
-just do this 4 times and your done.
Not that clear probs, sorry! tried to tell you wat i did but i cant explain it very well. hopefully you can use something to help you. It will probs take you 3hrs if you havent done it before, cause there will be some trial and error and maybe a mistake that can set you back.
The spade connectors, etc can be got in DIY stores or on ebay.
As for the speakers, you can probs get 4 17cm (around that size, like 16, etc) for like £50. I picked up my front door speakers, thats 2 speakers, for £30. They were basically new - Alpine Custom Fit Type E. Sound really good!
Hope i have helped a bit,
Good luck m8,
