(S) 3 Door Backseat Cards Speakers???

hi all, am new to the Forum as bought a Fiat Punto 1.2 Elx 8v last month. Very impressed so far. To the point - i was wondering if anyone has already done this and installed speakers, pref 6x9's in the 'door cards' of the back of a 3dr Mk2?

I saw a pic somewhere on the net of this on a MK1, looks the nuts, plus beats spoiling/making a new parcel shelf which blows all the sound up.

Anybody got any ideas on the best way of donig this? plus im thinking about wiring them (ampless for now) in the panels, rather than have cable all over the shop.

I think this is what JohnnyBoy (sp?) did with his mk1, the final outcome looks very good, but its a lot of work as you have to remove various other panels to take off the rear ones, not sure about a mk2 - I've never been in one
