Review on Polk Audio DB652 Ultramarine Speakers by Travis Rio

HOLY SHIT is all I can say. I replaced the factory speakers in my 2009 GMC Sierra 1500 with a factory head unit. I put them in the back doors. I think the main unit EQ concentrates the bass on the rear, so I chose those for that and the Fosgates for the front. For unamplified speakers, this is AMAZING. People who complain that they don't have bass are looking for quality subwoofer bass. This is unrealistic to expect from an unamplified 6.5" speaker. BUY NOW
