hi all just bought a 54 plate octy vrs want to keep origional head unit but want to upgrade the speakers and maybe fit a amp, what speakers and amp can you recommend been on the pionner web site but thers lots to choose from which should i go for

Personally I'd go for Dyn Audio component speakers although they are a bit pricey, so if these are out of your range I'd go for a set of Focal components, together with a Genesis amp. I had Focal 6" components and a Genesis 4 channel amp hooked up to my Alpine CVA-100 monitor in my old Polo 16v and it sounded amazing.
