i had a polk component set in a older eclipse, & i personally liked how it sounded, i dont know if i would say the clarity is better than the boston spz's i have in my new car, but where im from alot of people talk down on polk & boston because they never heard it, it seems like alot of ppl here are into rockford & kicker, but personally i only do boston or polk, after hearing the spg & the g5 in a shop down here i honestly think 1 spg is about equal to 2 12" g5's, i think its amazing how loud they pound with the small amount of airspace required, if i have time i'll get a picture of my setup.
