x2 on the magnum d2's and the cdt eurosports 3-way if you can...
just keep in mind that all equipment you're gonna be running remember the alternator upgrade, dominick irragi could probably build a quality alt for ya... don't know his email off the top of my head, but it's like the heart of the sound system, the hu being the brain...
one other thing, if you're gonna spend 400+ on a hu get an eclipse 8443, they run about 450, but you need to get them installed by a dealer for the security features, it's worth it. you just can't beat them. if you have an eclipse dealer nearby, talk to them about all the warranties, extras, etc. it has a decent eq, but you probably want to look into an Audiocontrol DQX (400 or so) 30 band graphic equilizer, has 8 memory presets, line driver, bla bla bla
good luck and enjoy!!!
