don't want to do any normal box for one, was thinking an infinate baffle or 4th/6th order ... try something new for a decent SQ woofer and do a SQ install in my friends car. can ajust amp depending on power handeling issues as no woofer amp is bought yet, 300/4 for mids, maybe another 300/4 to set a good stage later on with some 3-way's and components in A pillars
