I am thinking of upgrading my mk6 fiesta zetec but before getting work done I was wondering what the stock sound system actually was? In terms of size of speakers, wattage of head unit etc.

mattmk6

pretty much like any other ford system to be honest, you turn it up loud and it distorts!!!

the speakers are 5x7 if thats any help

Pieoter

So are all the speakers 5x7?

mattmk6

yes mate, one in each door and 1 behind each card in the back

Pieoter

Would there be enough space around the mounts to fit in 6.5inch splits without too cutting?

mattmk6

i dont know what you mean mate, sorry

Pieoter

How hard would it be to mount 6.5inch splits? Will they require lots of cutting to fit(cutting of the car not speaker)?

mattmk6

i dont know what 6.5 inch splits are mate

Pieoter

basically will 6.5inch speakers fit?

krokemon

yes they will fit but:
you have to use proper adaptors (plastic plate with a hole to fit the speaker)and nothing thicker that 3-4mm .othewise you will have to cut the mounting plate...
you have to place a spacer of about 6-7 mm between the speaker and the cover. otherwise if you place a good woofer its cone will repeatedly hit the cover.
The door itself is very well built, the bass will be deep (nearly 40Hz if good speaker are selected and a serious amp is installed), especially if you have the 3door version which has larger doors.
