Query: Polk Audio DB351 3.5-Inch Coaxial Speakers (Pair, Black)

not a bad sounding pair of speakers, a little bright on a stock infinity system in a07 dodge quad cab. they are clean and would sound nice on a aftermarket system where they would recive more power and some tuning. I would spend more money next time and get some thing better like herz
