Building your own power amps will not save you money!
By the time you have bought all the components you would have spent far more than buying something for sale on ebay. Most people are prepared to post amplifiers and the postal rates are cheaper than a long car journey. A quick search on ebay showed a seller selling 3 c-audio amps in Farnborough not far from you, local pickup only- 200 start. The 3 amps probably cost 3K+ when new......
For the money they will fetch you would be hard pushed to buy the output transistors and capacitors they contain.

Hi mate

To keep it simple, you want to x-over your tweeter passiv to the midrange.
So you need only two amps for the rig.
Then spend a little bit more for the 15". The suggested one is not really worth building a good cab for, but this is what you'll have to do to make the system sound anyway. The passive x-over can be done through testing n trying, but if you know someone who can messure frequencie response,
would be better. Must be a couple of designs in the www for your combination.

Jack
