Verfy that not many companies make 8 inch subs or that it was a pioneer? Well most companies only make 10inch and up now, and I live in a small town far from an bigger centers leaving me with two options, order one from the internet, or buy the only one I can get in through my local stereo shop, a Memphis. thats the verifaction. and the Pioneer is 11 years old that is in my car and probably really dry and weak by now.
