I got an MK1 (f reg)
When I got it there were no speakers in the rear, there were, however, on each parcel shelf support (left and right of parcel shelf) 2 grilles mounted in, each one for a 4" driver.
Up front right at the very front of the door pockets were 4" drivers screwed onto small plastic half-boxes with no backs, these were, and are s**t, 2 watts rms 5 watts max power, 160hz-10,000hz, i upgraded to
5" blaupunt AL-120
Longmill tweeters on-dash (glued them on there)
2x sony 6x9s in rear shelf
3x 10" subwoofers
you shut the doors and you could hear the bonnet and boot lid rattling, well thats what a FIAT is all about...
