I always thought Polk Audio had the best sounding 2 way 6 1/2" speakers until I bought a set of these JL Audio 6 1/2" speakers. JL Audio has proven me wrong! JL delivers the MOST accurate bass reproduction and clarity of ANY car stereo speakers I have owned. I have used everything from Alpine to Rockford and these are definitely the best, I LOVE THEM & everyone that's heard them agree. To me these are even better than componet speakers! These speakers just have the BEST of everything going for them, no fuzzy highs and no muddy bass. The best wattage for these speakers I have tried is 50-75 watts, Simply Great speakers!!!
