I am right in thinking I have got a maximum speaker mounting depth of 62mm in a Corsa B? Where can I find out the mounting depth of speakers so I know which ones will fit without door builds? Looking putting in some Focal Access 165A components that I'll be running off an Alpine T420 amp that I just managed to get off ebay for a very good price 
Ive been told Ill have to turn the gains down in order not to blow the speakers up running them off this amp. How do I turn the gains down on the amp?  Its all french to me but if someone can tell me how to do it then I'll be able to sort it out

yup 62mm WITH adaptors  Look up focal website and look on tech specs for info on depths etc. However, majority of focals will need door pods 
Gains are a simple control on the amp itself - it will all be in the manual etc

This is all Ive been able to find as the Focal website doesnt seem to be working
Focal Access 165A
2-way separate, Woofer: 165mm, Voice Coil: 25mm, Magnet: 72mm, Tweeter: Tioxyd TN 47, Crossover: 2-way 12dB/octave (with adjustable tweeter level), Max. power handling: 120W, Nom. power handling .: 60W, Sensitivity: (2,83 V/1m) : 92dB, Frequency response: 60Hz-20KHz
When it says magnet 72mm its talking about the diameter of the magnet rather than the depth of the magnet isnt it? Anyone know the depth of them? They look a lot shallower than other Focal speakers Ive seen

well i have found it.....
the mounting depth is 66.2 mm on the 165A's
However the 130A's are 57.2mm so they might be a better choice.

Ye I reckon they should fit but I'll phone Focal or send them an email to ask about the depth. What do I need to ask for so I get the right dimension of them? The speaker mounting depth?
Noticed Iaz has some audioscape door builds for sale that would fit these in nicely if they wont go in using the standard autoleads adaptor

^^^^ posted before I saw your 2nd post Adi.
Do you think there will be enough room behind the plastic door panel to space them out a bit off the adaptor 5mm so they clear the window or is space very tight?

if u pull the speaker out any then the rubber flange will rub on the plastic door card piece (might do even without) so no you deffo cant space them any without butchering the plastic cover.

Ok so Im gonna have to do some surgery on the door card which I can do as I have a spare set that I could work on.
Say if I went for the 130A's am I going to noticeably lose any sound quality or volume with them being smaller?

even at 50 odd like my infinity's with adaptors, the rubber presses against the grill - hence why ive had to sand down the verticle struts on the back of the grill to stop damage etc (although this just causes the whole lot to vibrate ).
tbh, if you a bit handy with fibreglass, then mark out the diameter of the speaker on the grill, cut it out and then mould in the speakers grill (that came with them) into the original corsa pocket - should stop it the rubber rubbing
Although as for speaker size, small mid range just means less bass response - although if you have a sub you wont notice anything anyways Just make sure you setup the filter correctly etc
