They're better than stock, but turn down the bass.
I bought these puppies close to a year ago. I've had 'em in my 1999 Explorer connected to an Aiwa 52x4 head unit. <BR><BR>They have ok sound, but not nearly as crisp and clear as several other higher-end products. They have next to no bass, and if you turn the bass up, they clip and distort badly. They're not bad when you have subwoofers, though. If you play them well within their RMS, they sound pretty good. I've played them loud, and they'll hit high volume (with the bass off), but not extremely clearly.<BR><BR>Bottom Line: For the money, they're not too bad. They don't have enough bass response, and they don't handle high volume well. I'd just recommend spending the extra 20 bucks to get a better quality speaker. If you do get them, subs are a must to accompany them.
