I fitted the Infinity fronts a couple of weekends back and they do make a big difference in sound clarity. Take the woofers as an example. The OE one looks like it's made from a sheet of cellophane and has a magnet the size of a 35mm spool case. A proper speaker has a decent sized magnet for a start and is made of something a bit more substantial.
Ordered a set of Reference 6522si shallow mount Co-ax's for the rear doors too. I should hopefully get them fitted this weekend.
