for sound quality, alot of guys use Image Dynamics and have positive things to say about them. I friend of mine has a trio of JL W7( may be out of your price range) for his SQ build and listens to ALL music. His setup is one of the cleanest/clearest I've ever heard, but he spent way more than you're willing to. the install makes alot of difference. proper enclosure, deadening, sound processors, gain settings, and tuning will give you good sound quality.
