I don't really know much about car audio, so any feedback will help me tremendously. Thanks

Nice choice on the amp, I dont know about the subs though. I would look into a pair of Adire Audio Shivas (www.adireaudio.com) they are a 12" sub, but way worth the extra $$$ (I have the JBL 600.1 runnin 2 of the Shivas myself, and I couldnt be happier). Or if you want 10" subs, I would look into the JL 10w3 or even the Alpine Type R, IMO

those tornadoes aren't bad for wetting your feet with, but you'll see that there are much better subs out there
