I have the Focal 100v setup in my dash , 5WS subwoofers in my doors. All were mounted with just slight modifications , using the stock speaker grills . 60 x 4 Audison amp powers them, with a Nak CD400 head unit. Not the cheapest, but not the most expensive either. Talk to Rod @
www.caraudioinnovations.com blinkwatt, he carries all these, except the 5WS which I believe they don't make anymore. Hes in Roseville, which shouldn't be too far away from you ( I believe). I really like the sound quality, crystal clear, and plenty loud for my needs
