General Front Speakers

[SilverSurfer]

I'm new to the forum and own a Y reg ('99) MK1 Punto 60SX and so am currently lacking the speakers in the doors, and really need to upgrade them as the tiny s**ty sound is driving me mental. Just wondered if anyone had changed the door cards for the ones off a GT and if they did how much did it cost, where from etc. and how difficult it was. Some advice would be sweet

Thanks
