I had Polk ex 5X7's in my '99 x-cab with a MTX 400 watt amp pushing them they sounded good but not great. I went and bought the reference series infinity's and installed them with the same Mtx amp, and DAMN!!! They sound excellent. A Kenwood head unit and a 8" bazooka make for a great set-up but need just A little more bass so next week a 8000 MTX 12" and a MTX THUNDER amp will be added. So anybody looking for a bazooka tube to buy e-mail me ...spiderwebb4043@cs.com..The piont of this post was to say GO WITH INFINITY

I also replaced my factory speakers with reference series Infinity Speakers. I am very pleased and impressed with the speakers. If you are considering replacing your factory speakers you need to consider the Infinity 5x7 reference series speakers.
