Another halfords employee here, a small word - try and make a differnt choice so you dont have a ripspeed unit. Bet you will bring it back within 2 months wanting something else!

Lol but they look all cool and shiny...

Need some speakers too an all... so didn't want to spend a bomb. I'm quite liking this Wharfedale brand being in the £30 mark to be honest. Because I was looking at 50-60 quid for both the unit and speakers.
I'm probably being over optimistic. (?)
Nearest car audio centre to me like the one Darkscamp suggested is Manchester. That's a trek and a half.
