I found local garage briancarsounds to install the audio + speakers.
I think the price is reasonable, quality of installation is good. No complaints.
The guys suggested Audison Prima speakers at the front.

and the radio I bought myself Kenwood DPX-7000DAB Car Stereo
Sound is amazing plus hands free functionality.
2 pairs of speakers (£150) installation work head unit (£50) speakers (£100) => Total £300
