mk3 speaker size and recommendations

[Kazama76]

Hey Guys

  New(ish) to the golf scene, and looking to uprate the speakers all round. Im both unsure of the sizes and unsure of the best make and model.
  Im not running a amp so direct HU and not planning on any subs. So after pretty good bass and all round good quality. (golly i dont ask 4 much :p)

Oh, i have around £150 - £200 to spend on audio

Any help is appreciated
