2010 GMC Sierra
These speakers sound great! You cannot go wrong with these polks. I just replaced some 6.5 in alpines with these cause one of the alpines popped after the second year and just made my Sierra complete cause I have the component Polks up at the front with a 50x4 Kenwood amp running them. There is a difference between the alpines and these the polks are much clearer and seem like they're louder because of the clear highs. Definitely recommend.
Pros: Love the sound. Great quality materials.
