Car Audio Installation Central Belt

[GK]

Hi all,

I'm looking for somewhere or someone in Scotland I can go to for advice and installation of decent car audio. Previously had an Audi with Bang and Olufsen speakers that were much better than the ones in the Golf I have now. I'm looking for somewhere to advise and fit decent speakers without wrecking the interior of the car in the process. Where's the best place to go? Any suggestions.

Cheers,
Alan
