yeah a little cutting was required but not as much as you may think......it needed two holes cutting, but the pods come with a cardboard guide that aligns with the molding on the inside of the door card. It's then a case of using a marker to trace the hole and then using a jigsaw to cut them.
The cardboard guide has two shapes - one if you have door speakers already, and another if you have no door speakers at all.
They were fairly pricey - GBP650, but that included 4 drivers, the pods and grilles, two crossovers, new dash pods which each house a 4" and a 1" tweeters.
They sound superb, and well worth the money IMO.
