Local shop is pushing me towards this brand. I have a factory ML Nav package in my 03 GS300. I just purchased a Pioneer NEX 4100 and the shops around me say its a nightmare to wire up with the factory ML package so, I'm thinking of upgrading everything; components, sub, etc...

I love the sound of my factory speakers but like everything in the world, I want better. I heard Hertz is good along with Focal also. The set I was looking into was the Clarus Stage IV. Does any one have any information on these speakers? My goal is to get something noticeably better than what I have but, in turn not destroy the band. I want to stay around 600 for the components not including the amp.
