Bought these to replace my factory speakers in an ex-cvpi,after I managed to kill the stock speakers. Took me about 30 minutes of install time to get them in,and after testing them,it was "lacking". While the mid's and high's sound great,when you turn it up to any reasonable volume with a song that has bass in it,all you get is distortion. As in stock speakers put these to shame. In an old cop car. I hope I'm getting the point through. Only good thing is the warranty on them.
