I put in alpine fronts, I had focals in my last car, they were nice, but not worth the price. I wanted something reasonable but not great as the factory head unit isnt amazing so super high end speakers wouldnt really mean much with the mediocre amp and tiny speaker wire.

I am looking at either a kenwood or clarion compact subwoofer. The kenwood has a passive device that is promising, the clarion is all aluminum. They aren't going to be great, but they will fill in the low end a bit.
