Afla 156 1999 speakers

[ihatesissycars]

Hey all, any ideas what size speakers the 156 has?

I have a 1999 model with the seperate front door tweeters but they distort easily and sound tinny so I want to replace them but, what with?

I've changed the head unit for one I already had which came form my last car and sounds great so a speaker change should give results.

Thankyou in advance!
