I got 2 Kenwood 6x9 speakers & 2 5 1/4 Pioneer speakers a while back in my truck. Just a few days ago I installed those speakers to a 4 ch sony amp. All I can say is wow! Alot More crisp, clear and louder than they were hooked to the headunit. NO more distortion. I got the Sony GT500 HU & if I turn the lower frequencies lower on the custom equalizer(more bass), i swear it sounds like I got an 8" sub or 2 installed. I recommend highly that u amp your speakers. The RMS of the HU is only 17W, the amp is giving the 6x9s about 55-60W each & the rears prolly about 30-35.
