Twingo 133 speaker query

[CButler-93]

Hi all. Just wanted to know if you can fit 17cm (6.25inch) into the front doors. I know the standard size is 17cm (5.25inch) but has anyone successfully fitied 17cm in without modifications?

I'm pretty sure the unit sizes of all the speakers on the RS are 13CM.
My guess is fitting 17's without any mod's is going to be next to impossible.
Though there are some direct fit alternatives, check out the Pioneer TS-1302i.
