Thinking of buying a Cinq, any ice tips?

Hi,

I currently own a mk2 ford fiesta and am looking to buy a cinq sporting. However I am worried that my current ice will not fit.

I currently have:
JVC Single CD Headunit,
5in Infinity reference components in the front,
4in Pioneer emotion 2-way coax in the rear,
Longmill 2x80wrms amp running the sub,
Kenwood 10in sub in 1.4cuft ported enclosure.

Questions!
1.) The standard front speaker size is 4in yes? Is it possible to fit 5in speakers there, or can i fit them in the door, etc...?
2.) Can i fit my 4in speakers in the rear quarters?
3.) Any mounting depth issues?
4.) Do these cars rattle a lot when theres quite a big system in there, so how much sound deadening would I have to do?

Thanks in advance.

Cheers,
Lee.

1) yes there 4in and no u can't fit 5in speakers in there. U may be abble 2 fit them in the door but it cud b kinda tight.
2)I believe u cud if u made some MDF cut outs 4 them.
3)not really but u'll have 2 check
4)Mind doesn't seem 2 rattle that bad my rear wiper does bcos of the sub and the dash has started 2 rattle a little 2 recently but not noticable really.
