Sounds AWESOME, in the RIGHT vehicle!
OK, I have noticed several bad reviews on this, and other 6"x8" speakers... and MOST of them own Ford Rangers. Everyone ELSE seems to love them! SO - DON'T put them in a RANGER!! I installed a pair in the doors of my '02 Ford Mustang without Mach system. Frankly, I have never heard a non-component, coaxial speaker with such tight mids, solid mid-bass, and crisp highs. They're powered by a PPI 75W RMS per channel amp. They take the power beautifully! I would probably have gotten the next level up JL Audio coaxials, for the extra power handling, but these have served me well, and compliment my JL Audio 10" Sub perfectly! Like some others, I also installed 150hz bass blockers on the door speakers - 5x7/6x8s were NEVER meant to be subwoofers, don't even try! If used as designed, these are fantastic speakers, and as a former car stereo installer, I HIGHLY recommend them!
Pros: Clean, crisp sound - in their DESIGNED frequency range. Great, hard hitting high bass.... Even BETTER with a moderate amp.
Cons: NONE, if used as described! ;)
