So i got a Astra H 2 door 2005

looking to replace the speakers

am i right in saying the front speakers are 6.5"?

what size are the tweeters? 25mm? and how do i know if others will fit? they are clips but there spaced further apart than 25mm

was looking at these http://www.pioneer.eu/eur/products/2...70Ci/page.html but there 28mm so not sure if they will fit, any ideas?

i know there are these, http://www.pioneer.eu/eur/products/2...172C/page.html

has anyone tested them out before? not sure if there worth the money
