I'm lookin to upgrade my audio this summer,
However, I'm a bit puzzled as to what I need.
Most threads are about self installation, however i'd most likely take it to the specialists therefore I would appreciate if you could give me advice as to what i need to buy and what they expect me to have before i take it to them to fit.
budget around £250-300 so just a basic upgrade
car: 2005 Astra sxi 1.6 5door.
i saw this and was wondering if it would suffice http://www.caraudiocentre.co.uk/prod...00_p-23125.htm
so i'd be lookin for speakers, sub, and amp? or something else?
