Thanks for the info. After a bit more reading I saw that we seem to have some good focal and DD locally. I'm looking at some focal 6" comps for the front door and maybe a 10" DD for the trunk if it's not too big. I want to keep as much trunk space as possible. I need a woofer that can still keep up so I don't want to go as big as 12". I'm thinking 10 would be a good compromise. One thing I kind of concerned about is counterfeits. I see some guys selling speakers for $400 a pair when they retail for about US$200. But there is a guy in chaguanas that I know has original focals and DD subs. What you think about a separate amp for the components and sub. I could fit the component amp under my seat and attach the sub amp to the sub box. The Rockford amp has bad reviews concerning it's temperature. I'm looking at some Alpine class D amps that are supposed to run really cool. I'm also thinking to go the 4 speaker, 2 tweeter, sub setup that you were talking about. I like to use the rear speakers to pull the sound back a bit so it sounds like it's coming from all around me but the best thing about rear speakers is that you can pull the music to the back if you want to have a convo with someone in the front seat. Not a big deal but it's convenient.
