Polk Audio subwoofer?

Im looking at this subwoofer and I'm not sure how good it is, its made by polk audio. Heres a link http://www.newegg.com/Product/Product.aspx?Item=N82E16882290085. I currently have and 8" JBL subwoofer in the back of my truck I like and was thinking of getting another one of those but this sounds like a good deal. The specs of the subwoofer look great and just wanted to know what others thought. Heres a link to my current sub I have http://www.crutchfield.com/p_109GTO804/JBL-Grand-Touring-Series-GTO804.html?tp=111.

Thanks,

Kmok

 

i work at a car audio shop polk audio is a good name.....its been around for a while, i put a set of subs in kind of like thatin a tahoe last week and they hammered id go for it.... what kind of amp you got?

 

I have a sony amp I believe its 600w maybe more cant remember the model #.

 

yeah that should sound good man good luck

 

Thanks for the help!

 

Hard to beat at that price with free shipping. It is the lowest level of Polk but I think you'd be happy.
