Speakers for £400 including amp and subwoofer

[Samanderton64]

hello i am looking to buy a speaker set including at least a sub woofer , an amp and 2 speakers. I know very little about speakers as i have never invested very much money into them. I was looking at the Q Acoustic 2020i and a few sub woofers but didn't get particularly far in my search before i started to realize i needed help. I am happy to spend a little more if needs be but i don't currently have the money for anything more. Any help given is appreciated thank you.

My suggestion for speakers is to get the Boston Acoustics A25. They are incredible for music. I don't use a subwoofer so I don't have a suggestion there. I also hear good things about the Wharfdale Diamond 220.
