Speaker instalation, PLZ dont ingnore, HELP THA RUSSIAN Options

[Niskyspy]

Uh, well this question was asked million of times and I know that you people are gonna get pissed at tme but pleas just answer. I dont have time to search cuz I got to do a lot of stuff today and I am buying 4 Alpine Type-S 6.5 today and I would really like to install them same day.
Here are my Q's:
1) For the front speakers, All I need to do is remove the whole door trim and then install the speakers right? There is no easier way to do this right?
2) For ther rear spakers (hatchback), Can I just pop off the grill and install them or do I need to take the whole rear trim to do it?

Thank you very much for your help.

I made my front adapter of MDF. The biggest ring that bolted on the outside was 4 mm thick. Indeed alone it would not be sufficient to hold the speaker for a long time. That why i made an extra ring on the innerside of the plastic mounting bracket which was 12 mm thick. So in al my MDF bracket is 16 mm thick and gives quite a punch. Only have to use some Dynamat now!
