My facelift Octavia came with the default sound system, and I am keen to tinker with it and upgrade it a bit. The first thing I'm doing is installing some sound deadening mats/acoustic foam around the place, and I thought that whilst I've got all the door trims off, I could put in some improved speakers.

 

What sort of speakers would usually get recommended for this application? I didn't want to make it too complex - I wasn't planning on adding a new amp, or necessarily a dedicated subwoofer (would adding a dedicated subwoofer imply the need for an upgraded amp and generally quite a lot more set up?)

Keen to hear results of this, that being said I am pre fl but I'm sure will be useful
