07 vw tdi speaker sizes?

Does anyone know what the speaker sizes are in the new 07 TDI Diesels? My brother is buying one, he say's it's a 10 speaker system. The local shop owes him a large amount of money so we are going to pre-order the system, I just want to know what speakers to get him. The front of my 06 Jetta is a 3 way system, but I also have no clue what the speaker sizes are. Any help and advise on this car would be great!2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.
