Save Polk Audio DB651 6.5-Inch Coaxial Speakers (Pair, Silver)

I purchased a set of four DB651's to replace the factory speakers in my 2004 Nissan Sentra. My intention was to replace the entire factory sound system piece by piece, but once I installed these speakers I realized I didn't need to change out my head unit or add an amp. These speakers sound perfect with the factory HU. I can turn the HU up to maximum volume and the Polk can handle it with no distortion. When I first installed them, I had a raspy popping sound, but I realized the factory subwoofer was still connected. Since disconnecting the Sub the sound has been perfect! These speakers pick up the bass perfectly, so I decided not to add a sub at all. The sound isn't competition quality, but more than what I'll ever need. Perfect full-range speakers for the average listener. Purchasing these speakers saved me a lot of money on replacing the rest of my system. Thanks Polk!!
